In terms of the number of cores, the cable includes 3 phase conductors and 1 neutral conductor, and some specifications can add a grounding conductor according to requirements. The cross-section of the neutral conductor is usually 50%-100% of that of the phase conductors. For example, 16mm² phase conductors can be matched with 10mm² or 16mm² neutral conductors, which can effectively balance the 3-phase current and avoid neutral point shift.

In terms of electrical performance, the insulation resistance of the XLPE insulation layer is ≥1000MΩ·km, the dielectric loss is ≤0.002, and it can withstand a 10kV power frequency withstand voltage test for 1 minute without breakdown. The shielding layer is wrapped with copper tape or aluminum-plastic composite tape with an overlap rate of ≥25%, and the grounding resistance is ≤1Ω, which can control electromagnetic radiation within 5μT.

In terms of mechanical performance, the tensile strength of the cable is ≥12MPa, the elongation at break is ≥150%, and the bending radius is not less than 10 times the outer diameter of the cable, which can meet the installation needs of narrow spaces. The flame retardant grade reaches V-0. In the vertical burning test, the flame spread length is ≤300mm, and no toxic halides are released.

In terms of temperature resistance, the normal operating temperature of the cable is 90℃. In case of a short circuit, the maximum operating temperature can reach 250℃ for no more than 5 seconds. At the same time, the cable can operate normally in an ambient temperature range of -40℃ to 90℃.

The AS/NZS standard 3-phase aluminum power cable (with neutral conductor and shielding layer) has distinctive applications in many fields due to its unique performance advantages.

Industrial plants are one of the important application scenarios of this cable. In various production workshops, the power supply of small and medium-sized motors is inseparable from it. For example, lathes, milling machines and other equipment in mechanical processing workshops require stable 3-phase power supply. Cables with a cross-section of 50mm² or more can meet their power needs and ensure the normal operation of the equipment. In food processing plants, because cleaning agents and other corrosive substances are often used in the production process, the corrosion-resistant sheath of the cable can effectively resist erosion and ensure the continuity of power supply. In chemical workshops, the temperature resistance and Chemical Resistance of the cable can also adapt to its special working environment, providing reliable power for reactors, mixers and other equipment.

In the power distribution system of commercial buildings, this cable also plays an important role. As a power distribution trunk, it transmits power from the transformer room to the distribution boxes on each floor, and then distributes it to various electrical terminals. In large shopping malls, air conditioning systems, elevator equipment, lighting systems, etc. all require a large amount of electricity, and cables with different cross-sections can be reasonably configured according to the load situation. Office equipment such as computers, printers, copiers in office buildings, as well as audio and projection equipment in conference rooms, also rely on this cable to provide stable power support. In addition, fire protection systems in commercial buildings, such as fire pumps and smoke exhaust fans, can also use this cable. Its flame retardant performance can gain time for personnel evacuation and fire fighting work in case of fire.

This cable is also widely used in the transmission network of municipal infrastructure. The street lamp system of urban roads uses this cable for power supply, and its weather-resistant design can adapt to outdoor wind, sun, rain and day-night temperature differences. Landscape lighting, fountain equipment, etc. in parks, squares and other public places can also use this cable. In sewage treatment plants, the corrosion resistance of the cable can cope with the erosion of the sewage environment and provide power for sewage treatment equipment. Various mechanical facilities in garbage treatment plants also need this cable to ensure power supply.

In places with strict requirements for electromagnetic compatibility, such as hospital MRI rooms and precision laboratories, the shielding layer of the cable can control electromagnetic radiation within 5μT, avoiding interference with precision equipment and ensuring the normal operation of the equipment. In the backup power system of data centers, the shielding layer can prevent electromagnetic interference generated by the cable from affecting the normal operation of servers and other equipment, ensuring the safe storage and transmission of data.

In the confluence lines of outdoor photovoltaic Power Stations, the weather-resistant design of this cable performs well. It can adapt to the outdoor environment of photovoltaic power stations, resist ultraviolet radiation and extreme temperature changes, and collect the power generated by photovoltaic panels and transmit it to the inverter. The power supply for related equipment in wind farms can also use this cable, and its lightweight characteristic reduces installation difficulty and cost.

In addition, the cable supports various laying methods such as open laying, pipe laying and direct burial, making it flexible to apply in different installation environments. In narrow cable wells, bridges and other spaces, its small bending radius requirement can also meet the installation needs.

The AS/NZS standard 3-phase aluminum power cable (with neutral conductor and shielding layer) focuses on the combination of performance and practicality in material selection, and its style design can also meet the installation needs of different scenarios.

The conductor is made of high-purity aluminum (purity ≥99.7%). After annealing treatment, its conductivity is significantly improved, reaching 61% IACS. Compared with Copper Conductors, Aluminum Conductors weigh only 1/3 of copper-Core Cables under the same current-carrying capacity, which greatly reduces the mechanical load during laying and reduces installation costs and difficulty. At the same time, aluminum has good ductility and processability, which is convenient for making conductors of various specifications.

The insulation layer is made of XLPE (cross-linked polyethylene) material with a temperature resistance of 90℃. XLPE material forms a three-dimensional network structure through cross-linking reaction, making it have excellent insulation performance, temperature resistance and mechanical performance. Its insulation resistance is ≥1000MΩ·km, which can effectively block current leakage and ensure electrical safety. The dielectric loss is ≤0.002, which can reduce energy loss and improve power transmission efficiency. In addition, XLPE material also has good aging resistance, which can extend the service life of the cable.

The shielding layer is made of copper tape or aluminum-plastic composite tape with an overlap rate of ≥25%. Copper tape has good conductivity and shielding effect, which can effectively suppress electromagnetic interference; aluminum-plastic composite tape combines the shielding performance of aluminum and the insulation performance of plastic, and at the same time reduces the weight of the shielding layer. The grounding resistance of the shielding layer is ≤1Ω, ensuring that electromagnetic radiation is effectively introduced into the ground to avoid interference with surrounding equipment.

The outer sheath is made of weather-resistant PVC (polyvinyl chloride) or PE (polyethylene) material. PVC Sheath has good mechanical properties, chemical corrosion resistance and flame retardant performance, and the price is relatively low; PE sheath has better low-temperature resistance, aging resistance and Flexibility, and is suitable for scenarios with higher requirements for sheath performance. Both sheath materials have a tensile strength of ≥12MPa and an elongation at break of ≥150%, which can withstand mechanical stress during laying and use. The outer sheath passes the AS/NZS 1199.3 ultraviolet resistance test, and has a service life of more than 20 years in outdoor exposed environments.

In terms of style, according to different shielding methods, the cable can be divided into two types: overall shielding and split-phase shielding. Overall shielding is to wrap a layer of shielding layer outside the cable core, which is suitable for most general environments; split-phase shielding is to wrap each phase conductor with a shielding layer separately, and then perform overall shielding, which has a better shielding effect and is suitable for places with extremely high requirements for electromagnetic interference.

In addition, according to different laying methods, the cable also has two styles: armored and non-armored. Non-Armored Cables are light in weight and flexible, suitable for indoor open laying, pipe laying and other environments; armored cables have an additional metal armor layer outside the sheath, usually Steel Tape armor or steel wire armor, which can improve the cable's resistance to mechanical damage and pressure, and are suitable for scenarios prone to external impact such as underground laying and bridge laying.

The color identification of the cable is clear. Phase conductors are usually distinguished by different colors, such as red, yellow, blue, etc., and neutral conductors are mostly black or gray, which is convenient for identification during installation and maintenance.

The production process of the AS/NZS standard 3-phase aluminum power cable (with neutral conductor and shielding layer) is complex and precise. Every link from raw material processing to finished product inspection is strictly controlled to ensure that the product quality meets the standard requirements.

The production of the conductor starts with the smelting of high-purity aluminum ingots to remove impurities, so that the purity of aluminum reaches more than 99.7%. The smelted aluminum liquid is made into aluminum rods through continuous casting, and the diameter of the aluminum rods depends on the final conductor specifications. Subsequently, the aluminum rods are drawn through a wire drawing machine in multiple passes to gradually form Aluminum Wires of the required diameter. During the wire drawing process, the drawing speed, die precision and cooling system must be accurately controlled to ensure that the Aluminum Wires have uniform diameter, smooth surface and good mechanical properties. After wire drawing, multiple aluminum wires are stranded together according to a certain stranding method to form a conductor. The stranding pitch is strictly controlled according to the cable specifications to ensure the roundness and flexibility of the conductor. The Stranded Conductor needs to be annealed, heated to 300-500℃ and then slowly cooled to eliminate internal stress and improve the conductivity and flexibility of the conductor.

The extrusion of the insulation layer is one of the key processes. Using XLPE material, first, XLPE particles are added to the extruder and melted and plasticized at high temperature (about 120-150℃). The melted XLPE is uniformly coated on the surface of the conductor through a die to form an insulation layer. During the extrusion process, the extrusion temperature, speed and pressure must be accurately controlled to ensure that the thickness of the insulation layer is uniform, the surface is smooth, and there are no defects such as bubbles and depressions. The thickness of the insulation layer must be strictly in accordance with the design requirements to ensure its insulation performance. After extrusion, the Insulated Wire core needs to undergo cross-linking treatment, usually by means of warm water cross-linking or steam cross-linking, heating the insulation layer to 100-120℃ and maintaining it for a certain time to make the XLPE molecules undergo cross-linking reaction, forming a three-dimensional network structure, thereby improving the temperature resistance, mechanical properties and insulation performance of the insulation layer.

The production process of the shielding layer is rigorous. For cables with copper Tape Shielding, the copper tape is wrapped around the insulated wire core or cable core according to the specified overlap rate (≥25%). During the wrapping process, the copper tape must be kept flat and tight to avoid wrinkles, breaks, etc. For aluminum-plastic composite tape shielding, its wrapping process is similar to that of copper tape, but attention must be paid to the bonding strength of the composite tape to ensure that no delamination occurs during subsequent processing and use. After the shielding layer is wrapped, grounding treatment is required to ensure that the grounding resistance is ≤1Ω.

The cabling process is used to strand 3 phase conductors and 1 neutral conductor together to form a cable core. During the stranding process, appropriate filling materials (such as polypropylene rope, etc.) are added according to the cable specifications to make the cable core structure round. The filling material must have certain flexibility and insulation performance, and meet environmental protection requirements. After cabling, a layer of tape (such as non-woven tape or plastic tape) may be wrapped to fix the cable core and prevent loosening.

The extrusion process of the outer sheath is similar to that of the insulation layer, but the material used is weather-resistant PVC or PE. The cabled core is put into the sheath extruder, and the molten sheath material is coated on the core through a die at high temperature (about 160-190℃) to form the outer sheath. During the extrusion process, various parameters must be accurately controlled to ensure uniform sheath thickness, close combination with the internal structure, and no gaps to prevent moisture and impurities from entering. For armored cables, before the sheath is extruded, an armor layer needs to be wrapped around the cable core. The armor layer should be wrapped tightly and evenly to ensure its protective effect.

Quality inspection throughout the production process is carried out. The diameter, resistance, tensile strength

and other parameters of the conductor are sampled and tested; the thickness, appearance, insulation resistance, voltage resistance performance of the insulation layer are comprehensively inspected; the overlap rate, grounding resistance, shielding effect of the shielding layer are strictly tested; the overall mechanical performance tests (such as tensile strength, elongation at break), aging resistance tests, flame retardant tests, low-temperature impact tests, etc. of the cabled cable are also conducted. Only cables that meet all AS/NZS standards and design requirements can leave the factory.

In addition, for the special properties of the cable, such as weather resistance and corrosion resistance, special tests are also conducted. For example, ultraviolet aging tests are carried out to expose the cable to ultraviolet rays of a certain intensity for a certain period of time to detect changes in its performance; chemical corrosion resistance tests are performed to immerse the cable in specific chemical solutions to observe the changes in its sheath and insulation layer.

The packaging of AS/NZS standard 3-phase aluminum Power Cables (with neutral conductor and shielding layer) is designed to ensure the protection of the products during transportation and storage, preventing damage from external factors.

For cables with smaller cross-sections (10mm²-50mm²), plastic cable reels are commonly used. These reels are lightweight, making them easy to handle and store. The diameter of plastic reels typically ranges from 600mm to 1000mm, depending on the length of the cable. The cable is neatly wound around the reel with appropriate tension to avoid loosening or tangling. Both sides of the reel are equipped with plastic flanges, which are higher than the wound cable to prevent the cable from slipping off during handling. The surface of the wound cable is covered with a layer of plastic film to provide dust and moisture protection. Each plastic reel is labeled with essential information, including product name, specification model, cross-sectional area, number of cores, length, weight, production batch number, applicable standards (AS/NZS), and flame retardant rating, facilitating easy identification and management.

For larger cross-section cables (70mm²-400mm²), wooden cable reels are preferred due to their higher strength to bear the heavier weight. The diameter of wooden reels usually ranges from 1200mm to 1800mm. Similar to plastic reels, the cable is tightly wound, and the outer layer is covered with plastic film. For export to regions like Australia and New Zealand, wooden reels must undergo fumigation treatment to comply with international phytosanitary regulations, and a fumigation certificate is provided along with the shipment. A forklift hole is pre-drilled at the center of the wooden reel to enable easy loading and unloading using forklifts.

When multiple cable reels need to be transported together, they are consolidated on pallets. The reels are securely stacked on the pallet and wrapped with stretch film to prevent movement or collision during transit. For long-distance transportation or sea freight, additional waterproof measures are taken, such as covering the pallets with waterproof tarpaulins to protect against rain and moisture.

During storage, the cables should be kept in a dry, well-ventilated, and cool warehouse, away from direct sunlight, rain, and snow. The cable reels should be placed horizontally on a flat surface, and wooden blocks can be placed underneath to prevent contact with moisture from the ground. Cables of different specifications and models should be stored separately with clear labels for easy access and management. Regular inspections of the packaging integrity are necessary during storage to ensure the cables remain in good condition.

The transportation of AS/NZS standard 3-phase Aluminum Power Cables (with neutral conductor and shielding layer) requires careful planning to ensure timely and safe delivery to the destination.

For short-distance transportation (within 500km), road transport is usually the preferred option. Suitable vehicles, such as trucks with flatbeds or enclosed vans, are chosen. The truck bed must be clean, free of sharp objects, and dry to avoid damaging the cable reels. During loading, the reels are lifted onto the truck using forklifts or cranes and secured firmly with steel straps or chains to prevent shifting or rolling during transit. For multiple layers of reels, cushioning materials like rubber pads are placed between layers to reduce friction and impact.

For long-distance transportation, rail transport is often more economical, especially for large quantities of cables. The cable reels are loaded into rail freight cars and properly fixed to ensure stability during train movement. Sea transport is suitable for international shipments to Australia, New Zealand, and other countries. During sea transport, the reels are loaded into containers, and additional bracing is used to prevent movement due to ship vibrations. Waterproof covers are applied to protect against saltwater and humidity.

Air transport is reserved for urgent orders or small quantities of cables due to its higher cost. The packaging for air transport must comply with airline regulations regarding weight and dimensions, and the reels are securely packed to withstand the rigors of air travel.

During transportation, it is essential to avoid excessive vibration, impact, or extrusion of the cable reels. Direct sunlight for prolonged periods should be prevented to avoid premature aging of the cable sheath. In cold weather, although the cable has good low-temperature resistance, prolonged exposure to extremely low temperatures should be avoided to prevent the sheath from becoming brittle. In hot weather, ventilation measures should be taken to prevent overheating inside the transport vehicle.

Upon arrival at the destination, the recipient should inspect the goods together with the transporter. The inspection includes checking the integrity of the packaging, verifying the number of reels against the delivery note, confirming the specifications and models of the cables, and ensuring there is no visible damage to the cables. Any discrepancies or damages should be documented immediately, and the relevant parties should be notified for prompt resolution.
