Core Cable (Na2xy 3×150 Sm) has rigorous settings in terms of specification parameters. Each parameter is carefully considered to ensure its stable performance in power transmission.
The core specification of this cable is 3×150mm², which means it contains 3 cores with a cross - sectional area of 150mm² and can carry a large current. Under standard working conditions, its continuous current - carrying capacity can reach about 300A, which can fully meet the needs of medium and high - power power transmission and is suitable for various scenarios requiring high power supply.
Its rated voltage is 0.6/1kV, which conforms to the general standard of low - voltage power distribution systems. Among them, 0.6kV is the phase voltage and 1kV is the line voltage. It can be perfectly compatible with common low - voltage power distribution equipment, ensuring that there will be no faults due to voltage mismatch during power transmission and laying a foundation for the stability of power transmission.
The insulated ground conductor is an important part of the cable, and its insulation performance meets relevant standards. The insulation resistance is not less than 1000MΩ·km at room temperature, which can effectively prevent current leakage and ensure the safety and reliability of the grounding function. At the same time, the cross - sectional area of the ground conductor is compatible with the main core, ensuring that when there is a leakage, the current can be quickly introduced into the ground to avoid safety accidents.
In addition, the bending radius of the cable is 12 times the outer diameter of the cable, which can adapt to a certain degree of bending and laying needs, and can be installed normally in some laying environments with limited space or needing to turn. It has a wide operating temperature range and can maintain stable performance between - 40℃ and 70℃, and can adapt to different climate and environmental conditions.
(II) Characteristic Uses
Power Cable Yaxv Multi - core Cable (Na2xy 3×150 Sm) has a wide range of targeted applications in many fields relying on its own performance advantages, and can meet the power transmission needs in different scenarios.
It is an ideal choice in the field of industrial power distribution. In the production workshops of factories, there are many large - scale production equipment, such as large - scale CNC machine tools and punch presses. These equipment need stable high - power power supply. The 3×150mm² specification of the cable can provide sufficient current - carrying capacity to ensure the normal operation of the equipment. At the same time, the insulated ground conductor can effectively prevent equipment leakage and provide guarantee for the production safety of the workshop. In the main line from the factory's substation to the workshop's main distribution box, the cable can also play an important role in ensuring that power is stably transmitted from the substation to each workshop.
The cable is also competent in the power distribution system of large - scale buildings. For large - scale buildings such as shopping malls and office buildings, the total power consumption of internal air conditioning systems, elevators, lighting and other equipment is large. Cables with 3×150mm² specification can be used as the main power distribution lines of the building, connecting from the main distribution box of the building to the distribution boxes of each floor, and providing support for the power supply of the entire building. In these places with dense personnel, the existence of insulated ground conductors can greatly reduce the risk of leakage and ensure personnel safety.
In the field of public facilities, the cable also has application space. For example, large - scale public venues such as gymnasiums and exhibition halls need a large number of temporary electrical equipment, such as stage lighting and sound, when holding activities. The cable can be used as the main line of temporary power supply lines to meet the power demand of high - power equipment. At the same time, its good insulation performance and grounding function can adapt to the complexity of the temporary laying environment.
In addition, the cable can also play a role in new energy - related supporting facilities. For example, in the low - voltage line from the inverter to the booster station of a photovoltaic
Power Station, it can be used for power transmission, and its stable current - carrying capacity and safety performance can meet the requirements of photovoltaic power transmission.
(III) Material and Style
The material selection and style design of Power Cable Yaxv Multi - core Cable (Na2xy 3×150 Sm) are closely related to its performance and use, providing a strong guarantee for its stable operation and convenient installation.
The core is made of high - purity copper with a purity of more than 99.95%. High - purity copper has excellent conductivity and extremely low resistivity, which can minimize energy loss during power transmission and improve power transmission efficiency. The core adopts a multi - strand stranded structure, which is made of multiple fine
Copper Wires stranded together. This structure enhances the
Flexibility of the core, enabling it to better adapt to bending paths during laying and reducing the possibility of fracture. At the same time, the stranded structure can also improve the mechanical strength of the core, making it not easy to be damaged when pulled by external forces.
The insulation layer is made of high - quality polyvinyl chloride (PVC) material, which has good insulation performance and chemical corrosion resistance. It can effectively isolate the current conduction between cores and between cores and the external environment, ensuring the safety of power transmission. The
PVC Insulation layer has good temperature resistance. It can maintain stable performance below 70℃ without softening, deformation and other situations, and is suitable for general use environments.
The insulation layer of the insulated ground conductor is also made of PVC material, and after special treatment, its insulation performance is more reliable. The surface of the ground conductor has a clear logo, which is convenient for installation and maintenance personnel to identify and avoid wiring errors.
In terms of style, the cable has a multi - core cabling structure and is round as a whole. The multi - core structure can meet the needs of three - phase power supply. The round structure enables the cable to bear uniform force during laying, and is convenient to match with laying facilities such as pipes and cable trays. The outer sheath of the cable is made of black PVC material with a smooth surface, and is printed with clear marks, including model, specification, rated voltage, manufacturer and other information, which is convenient for identification and traceability.
(IV) Production Process
The production process of Power Cable Yaxv Multi - core Cable (Na2xy 3×150 Sm) is rigorous and standardized. Each link from raw material processing to finished product inspection has strict quality control to ensure that the product meets relevant standards and design requirements.
Core stranding is the first step of production. High - purity copper rods are drawn into fine copper wires with uniform diameter through a wire drawing process. During the wire drawing process, the wire drawing speed and die precision are strictly controlled to ensure that the surface of the copper wires is smooth and free of burrs. Then, according to the specification requirements of 150mm², a certain number of fine copper wires are stranded by a stranding machine. During stranding, stable tension and appropriate pitch are maintained to make the
Stranded Core have a compact and round structure, and at the same time ensure the flexibility of the core. After stranding, annealing treatment is carried out to eliminate the internal stress generated during the stranding process and further improve the conductivity and flexibility of the core.
The insulation extrusion link is crucial. First, the PVC
Insulation Material is dried to remove moisture from the material to avoid bubbles in the insulation layer. The dried PVC material is sent to the extruder, melted at a set temperature (usually 160 - 180℃), and evenly coated on the outside of the core through a special extrusion die to form an insulation layer. During the extrusion process, the extrusion speed, temperature and pressure are accurately controlled to ensure that the thickness of the insulation layer is uniform (the deviation does not exceed ±0.1mm), the concentricity with the core is high (the eccentricity does not exceed 10%), and the surface is smooth and free of defects.
The cabling process is to strand 3
Insulated Cores and insulated ground conductors together according to a certain stranding pitch. Filling materials are placed during stranding to make the cabled cable round. At the same time, stable tension is maintained during the stranding process to prevent the cores from loosening. The filling material is a non - hygroscopic material, which can prevent water from entering the cable and ensure the insulation performance of the cable.
Outer sheath extrusion is the last key process. The
PVC Sheath material is sent to the extruder, melted at a suitable temperature, and evenly coated on the outside of the cabled core through an extrusion die to form an outer sheath. During the extrusion process, the process parameters are controlled to ensure that the sheath has a uniform thickness, a smooth surface and is closely combined with the internal core. The sheath can protect the internal core from external mechanical damage, moisture, corrosion and other influences.
In the finished product inspection link, a comprehensive test is carried out on the conductivity, insulation performance and mechanical performance of the cable. The conductivity of the core is checked through a DC resistance test, the insulation effect of the insulation layer is verified through insulation resistance and voltage withstand tests, and the mechanical strength of the sheath is inspected through a tensile test. Only cables with all indicators qualified can leave the factory.
II. General Product Information
(I) Packaging
The packaging design of Power Cable Yaxv Multi - core Cable (Na2xy 3×150 Sm) focuses on protecting the integrity of the cable during storage, transportation and handling, and at the same time takes into account the convenience of packaging and the clarity of identification.
For coiled cables, wooden cable reels are used for packaging. The diameter of the cable reel is 1.5 - 2 meters, which can stably bear the weight of the cable. The cable is neatly wound on the cable reel, and appropriate tension is maintained during winding to make the cable arranged closely without looseness or distortion, avoiding surface damage caused by mutual friction. Both sides of the cable reel are equipped with baffles, and the height of the baffles is higher than the winding height of the cable to prevent the cable from slipping during transportation and storage.
The outside of the cable reel is wrapped with a layer of plastic film to play a role in moisture - proof and dust - proof. For cables that need long - distance transportation or storage in a humid environment, a layer of waterproof canvas is covered outside the plastic film to further enhance the moisture - proof and sun - proof performance.
A detailed label is pasted on the baffle of the cable reel. The label is marked with product name, model, specification (3×150mm²), length, production batch number, production date, rated voltage, implementation standard, manufacturer name and contact information. The label is made of wear - resistant and waterproof material to ensure that the information is clearly identifiable during transportation and storage. At the same time, warning signs such as "Handle with Care", "Moisture - proof", "Sun - proof" and "Do Not Press Heavily" are also marked on the label.
For small batches or short sections of cable samples, solid cartons are used for packaging. Foam liners are placed inside the cartons to fix the cables in the foam liners to prevent shaking and collision during transportation. Relevant product information and warning signs are also marked on the outside of the cartons.
(II) Transportation
The transportation of Power Cable Yaxv Multi - core Cable (Na2xy 3×150 Sm) must follow strict specifications to ensure that the cable is not damaged during transportation and its performance is not affected.
The transportation method is selected according to the transportation distance and quantity. For long - distance transportation with a large quantity, railway transportation or road freight is preferred. Railway transportation has good stability and can reduce jolting during transportation. The cable reels are fixed in the freight carriage, and steel wire ropes or special fastening belts are used to firmly connect the cable reels to the carriage to prevent sliding. For road freight, trucks in good condition with sufficient carrying capacity are selected. The carriage must be flat, clean and free of sharp debris. An appropriate gap is left between the cable reels, and they are separated by buffer materials to prevent mutual collision.
Short - distance transportation can use small trucks or logistics vehicles. Special hoisting equipment is required when loading and unloading cables. The hoisting point should be selected at the central axis of the cable reel. Hoisting from the side of the cable reel or the cable itself is strictly prohibited to prevent deformation of the cable reel or damage to the cable. Handle with care during loading and unloading to avoid violent collision.
The following matters should be noted during transportation: Cables should avoid open - air transportation. If it is unavoidable, they must be covered with waterproof canvas to prevent exposure to the sun and rain; keep away from fire sources, heat sources and corrosive substances. Transport vehicles are not allowed to approach open fire areas and are not mixed with corrosive goods such as acids and alkalis; during transportation, drivers should drive steadily, avoid violent operations such as sudden braking and sharp turns, and reduce the shaking of the cable reels; regularly check the fixing of the cable reels and reinforce them in time if they are loose.
After arriving at the destination, the receiver shall check the packaging and appearance of the cable together with the transporter, and sign for it only after confirming that there is no damage.
