PENDAHULUAN PRODUK

Detailed Description of 0.6/1kV ARVFV Series Industrial Armoured Cables (4X35 to 4X150)

I. Core Information of the Product Itself

(I) Analysis of Specification Parameters

The specification parameters of the 0.6/1kV ARVFV series Industrial Armoured Cables are the core foundation for their adaptation to industrial scenarios. Each parameter is precisely designed to meet the stringent requirements of industrial power consumption.

Voltage Level: The rated voltage of this series of cables is 0.6/1kV, where "0.6kV" refers to the rated voltage between the core and the ground or the shielding layer, and "1kV" refers to the rated voltage between cores. This voltage level makes it suitable for medium and low-voltage power distribution systems, covering the power supply needs of most equipment in the industrial field, from small and medium-sized motors to the distribution networks of large production lines.

Core Structure and Cross-Section Specifications: All cables in the series adopt a "4X" structure, which includes 4 independent Insulated Cores, corresponding to three-phase live wires and one neutral wire respectively, perfectly adapting to the three-phase four-wire power distribution mode commonly used in industry. There are 5 cross-section specifications available, with specific parameters as follows:

4X35mm²: The cross-sectional area of a Single Core is 35mm², the conductor diameter is approximately 7.4mm, and the rated current-carrying capacity (in air) is about 130A, suitable for small and medium-sized machine tools, conveyor belts and other equipment;

4X70mm²: The cross-sectional area of a single core is 70mm², the conductor diameter is approximately 10.5mm, and the rated current-carrying capacity is about 200A, which can meet medium-power equipment such as injection molding machines and small compressors;

4X95mm²: The cross-sectional area of a single core is 95mm², the conductor diameter is approximately 12.0mm, and the rated current-carrying capacity is about 240A, suitable for large fans, pumps and other equipment;

4X120mm²: The cross-sectional area of a single core is 120mm², the conductor diameter is approximately 13.5mm, and the rated current-carrying capacity is about 280A, suitable for high-power heating equipment and production line main distribution boxes;

4X150mm²: The cross-sectional area of a single core is 150mm², the conductor diameter is approximately 15.0mm, and the rated current-carrying capacity is about 320A, which can meet the power supply needs of large industrial kilns and heavy machinery.

Conductor Material: The core conductor is made of high-purity electrolytic copper (purity ≥ 99.95%), with a conductivity of ≥ 100% IACS (International Annealed Copper Standard), ensuring extremely low resistance loss during current transmission. The Copper Conductor has undergone toughening treatment, with good Flexibility, and is not easy to break even when repeatedly bent or dragged, facilitating laying operations in complex industrial environments. For some models, Aluminum Conductor options can be provided according to customer needs. The aluminum conductor uses high-purity aluminum rods (purity ≥ 99.7%), and its conductivity is improved through optimized annealing process. The cost is lower than that of Copper Conductors, which is suitable for scenarios sensitive to cost and with slightly lower current-carrying capacity requirements.

Insulation and Sheath Materials: The insulation layer is made of cross-linked polyethylene (XLPE) material with a temperature resistance level of 90℃. This material forms a three-dimensional network structure through a peroxide cross-linking process, and has excellent aging resistance, chemical corrosion resistance and electrical insulation performance. In the ambient temperature range of -40℃ to 90℃, the insulation layer will not harden, crack or soften, ensuring long-term stable insulation effect. The sheath layer is made of weather-resistant polyvinyl chloride (PVC) or chlorinated polyethylene (CPE). Among them, the PVC Sheath has good mechanical strength and flame retardancy, while the CPE sheath is better in oil resistance and ozone resistance, and can be selected according to the chemical characteristics of the use environment.

Armour Structure: As the core protective layer of industrial Armoured Cables, the armour structure is divided into two types: Steel Tape armour (ST2) and steel wire armour (WS2). The steel tape armour adopts 0.3-0.5mm thick hot-dip galvanized steel tape, which is wrapped around the outer layer of the sheath through a spiral winding process, with excellent resistance to extrusion and impact, suitable for buried laying or scenarios that may be crushed by heavy objects; the steel wire armour uses high-strength galvanized steel wires with a diameter of 1.2-2.0mm, arranged in a concentric stranding manner, with extremely strong tensile strength, suitable for vertical laying (such as mines, high-rise building shafts) or occasions that need to bear large tensile forces. Both armour structures have undergone anti-corrosion treatment and can be used for a long time in humid, dusty or slightly corrosive environments.

Other Key Parameters:

Bending radius: Not less than 12 times the outer diameter of the cable for static laying, and not less than 20 times for dynamic laying, to ensure that the core or insulation layer will not be damaged due to excessive bending during installation;

Short-circuit current tolerance: In an environment of 25℃, it can withstand a short-circuit current impact of 25kA within 3 seconds, avoiding conductor fusing or insulation breakdown caused by instantaneous large current;

Flame retardant grade: Passed the bundle combustion test of GB/T 18380.3-2008 standard, reaching the class B flame retardant requirement, which can effectively delay the spread of flame and reduce smoke release in case of fire.

(II) Characteristics and Core Advantages

The core competitiveness of the 0.6/1kV ARVFV series industrial armoured cables stems from their in-depth optimization for industrial scenarios, which is specifically reflected in the following aspects:

1. Full-Scenario Protection Capability

Industrial environments are often accompanied by multiple challenges such as mechanical impact, chemical corrosion, and extreme temperatures. This series of cables achieves full-scenario adaptation through a triple protection structure of "insulation layer + sheath layer + armour layer". For example, in mining scenarios, steel wire armour can resist the impact and dragging friction of falling ore; in chemical workshops, the chemical corrosion-resistant CPE sheath can resist acid and alkali vapor erosion; in metallurgical plants, the XLPE insulation layer can withstand high-temperature radiation, ensuring that the cable operates normally in an environment above 80℃.

2. Efficient Power Transmission Performance

High-purity copper conductors and optimized core structure (compact stranding process) make the DC resistance of the cable 5%-8% lower than the national standard. For example, the 20℃ DC resistance of 4X150mm² cable (copper conductor) is ≤ 0.124Ω/km, which is much lower than the national standard upper limit of 0.153Ω/km. The low resistance characteristic reduces Joule loss during power transmission. Taking 4X150mm² cable transmitting 300A current as an example, it can save about 500 kWh of electricity per kilometer per year (calculated by operating 8000 hours per year).

3. Flexible Adaptation and Expandability

The 5 cross-section specifications cover the power range from 10kW to 200kW, and users can flexibly select models according to the rated power of the equipment and the transmission distance (considering voltage drop). For example, for a 110kW motor (rated current about 220A) 50 meters away from the distribution box, selecting 4X95mm² cable can meet the requirement of voltage drop ≤ 5%; if the distance is extended to 100 meters, it is necessary to upgrade to 4X120mm² cable. In addition, the cable is compatible with various industrial connectors and terminals, facilitating system expansion or transformation.

4. Long-Term Reliability Design

The service life of the cable is designed to be 30 years, which is much higher than the 15-year standard of ordinary civil cables. This is due to the following designs:

The insulation layer uses water tree resistant XLPE material, which can inhibit insulation aging caused by water penetration;

An isolation layer (non-woven fabric or mica tape) is set between the armour layer and the sheath layer to avoid wear caused by direct friction between the metal armour and the sheath;

A semi-conductive water-blocking tape is used between the conductor and the insulation layer to prevent water from penetrating into the insulation layer along the conductor gap.

(III) Characteristic Uses and Application Scenarios

With its industrial-grade performance, this series of cables is widely used in the following scenarios:

1. Heavy Industrial Manufacturing

In scenarios such as automobile production lines, steel mills, and heavy machinery factories, the equipment generates strong vibration and mechanical impact during operation, and the armour layer can protect the cable from damage. For example, the power supply line of the robotic arm in the automobile welding workshop needs to be bent frequently, and the flexibility and armour protection of the 4X70mm² Cable can ensure trouble-free continuous operation; the rolling mill equipment in the steel mill has a power of up to 150kW, and the 4X150mm² cable can stably transmit large current and withstand high-temperature environments.

2. Energy and Mining Fields

In underground working environments such as coal mines and non-ferrous metal mines, cables need to withstand the tests of humidity, dust and mechanical dragging. The 4X95mm² cable with steel wire armour can be used for power supply of underground roadheaders, and its tensile design can adapt to frequent movement in roadways; the box transformer to collector line in wind farms often uses 4X120mm² cable, and the steel tape armour can protect the cable from soil pressure and gnawing by rodents during buried laying.

3. Infrastructure and Public Utilities

In places such as sewage treatment plants and waste incineration plants, cables need to withstand corrosive gases and liquid erosion. The 4X35mm² cable with CPE sheath can be used for power supply of submersible pumps in sewage treatment pools, and its acid and alkali resistance ensures long-term stable operation; the 4X150mm² cable is selected for the section tunnel distribution lines of urban subways, and the flame-retardant armour design can ensure Emergency Power Supply in case of fire.

4. Temporary and Mobile Power Supply

In scenarios such as construction sites and temporary power distribution for large events, cables need to be frequently transported and laid. The lightweight design (weight per meter is about 2.5-4.0kg) of 4X50mm² (derivative specification outside the series) and 4X70mm² cables is convenient for manual handling, and the armour layer reduces wear during dragging, meeting the flexibility and durability requirements of temporary power supply.

(IV) Production Process and Quality Control

The excellent performance of the cable comes from strict production processes and quality control, with specific processes as follows:

1. Conductor Manufacturing

Oxygen-free copper rods (purity 99.99%) are selected, and processed into single wires by continuous extrusion machines. The diameter of single wires is controlled between 0.5-2.0mm according to the cross-section specifications;

The bunch stranding + compacting process is adopted to strand the single wires into cores, with a compaction coefficient of 0.92 (0.85 for ordinary stranding), reducing core gaps and lowering skin effect loss;

The Stranded Conductor is annealed (temperature 300-400℃) to eliminate processing stress and improve flexibility.

2. Insulation Extrusion

Three-layer co-extrusion equipment (conductor shielding layer + insulation layer + insulation shielding layer) is used to ensure uniform thickness of the insulation layer (deviation ≤ 0.1mm);

After extrusion, the XLPE material passes through a cross-linking tube (temperature 180-200℃, pressure 0.8MPa) to complete the cross-linking reaction, ensuring a cross-linking degree of ≥ 75%;

The insulated core is tested by a spark tester (voltage 10kV) to ensure no pinholes and other defects.

3. Cabling and Armouring

The 4 insulated cores adopt a twist-free cabling process, arranged in an S/Z stranding manner to reduce torque stress during laying;

After cabling, a non-woven fabric isolation layer is wrapped to prevent friction between cores;

The armouring process uses a fully automatic armouring machine, and the winding pitch of steel tapes/wires is controlled at 10-12 times the outer diameter of the cable to ensure that the armour layer is tightly attached and uniform.

4. Sheath Extrusion and Finished Product Inspection

The sheath material is dried (moisture content ≤ 0.05%) and then coated on the armour layer by an extruder, with the thickness controlled between 1.8-3.0mm according to specifications;

The finished cable undergoes multiple tests: including DC resistance test, insulation resistance test (≥ 1000MΩ·km), power frequency withstand voltage test (3kV/5min without breakdown), partial discharge test (≤ 10pC), etc.;

10% of each batch of cables is sampled for bending test and aging test (after 135℃ × 168h, the insulation tensile strength retention rate is ≥ 80%).
