ZC-YJV 0.6/1kV 3x240+2x120mm²
PVC insulated and sheathed power cable

Product Features and Applications

• The main characteristic of flame-retardant power cables is that the cables are not easily ignited or the ignition delay is limited to a certain range. They are suitable for power stations, subways, tunnels, coal mines and other places with high cable laying levels.

• The main characteristic of fire-resistant power cables is that they can not only transmit electricity under normal working conditions, but also maintain normal operation for a certain period of time during fire and combustion. They are suitable for places related to fire safety and firefighting, such as nuclear power plants and high-rise building tunnels.

• Polyvinyl chloride insulated polyethylene sheathed power cables have good electrical performance and chemical stability, simple structure, and easy use. This product is suitable for transmission and distribution lines with AC rated voltage below 0.6/1KV.

• Places with special requirements for smoke density, toxicity index, etc., such as nuclear power plants, tunnels, etc. The characteristics of low smoke and low halogen flame-retardant cables are that the cables not only have flame-retardant properties, but also have the ability to emit smoke and are harmless (with less toxicity and corrosiveness), making them suitable for flame-retardant cables.

• This product is manufactured in accordance with GB/T12706.1-2008 or IEC 60502 standards. It can also be produced to other standards as required by customers.

• In addition to complying with the above standards, flame-retardant cables are divided into four flame-retardant grades A, B, C and D for flame retardancy as specified in GB/T19666. Grade A has the best flame retardant performance, and customers can select according to their needs.

• The fire-resistant performance of fire-resistant cables meets the requirements of GB/T19666 (750-800°C / 90-105min). Customers can select according to application scenarios and requirements.

• Low-smoke low-(zero-)halogen flame-retardant cables are produced in accordance with relevant standards. Their flame retardancy is classified into four grades A, B, C and D as stipulated in GB/T19666, with light transmittance ≥30% and hydrogen chloride emission ≤100mg/g.

• Ambient temperature: 40°C for installation in air; 25°C for direct burial installation.

• Operating temperature of cable conductor: 90°C.

• For buried cables, soil thermal resistivity ρ=1.0 °C·m/W. This does not take into account the increase of soil thermal resistivity caused by moisture migration during long-term operation of cables. When the cable is buried, the distance from cable axis to ground surface is 1000 mm.

• Flat laying of multiple cables, axial spacing between cables S=2D.

• The maximum temperature of cable conductor under normal operation is 70°C.

• In case of short circuit (maximum duration not exceeding 5s), the maximum temperature of cable conductor shall not exceed 160°C.

• The ambient temperature shall not be lower than 0°C during cable laying.

• The bending radius during cable laying shall not be less than the following requirements: Single-core cable: 20(D+d) mm; Multi-core cable: 15(D+d) mm (D and d are respectively the outer diameter of cable and nominal diameter of main conductor, unit: mm).
