Rated voltage 0.6/1kV
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.

Manufacturing Standard

• This product is produced in accordance with GB/T12706.1-2008 or IE60502 standards, and can also be produced according to other standards requested by the user.

• In addition to the above standards, flame-retardant cables are classified into four categories based on GB/T19666 standards: A, B, C, and D. The A-level category has the best flame-retardant performance and users can choose according to their needs.

• The fire resistance performance of fire-resistant cables meets the standard requirements of GB/19666. (750-800C/90-105min) Users can choose according to their usage scenarios and requirements.

• Low smoke, low (no) halogen positive flame type cables are produced according to relevant standards, and their combustion performance is divided into four different positive flame categories A, B, C, and D according to the GB/T19666 standard, with a light transmittance of not less than 30%. The amount of hydrogen chloride released shall not exceed 100mg/g.

Product usage characteristics

• The maximum temperature of the cable conductor during normal operation is 70C.

• The maximum temperature of the cable conductor during a short circuit (with a maximum duration of no more than 5 seconds) shall not exceed 160 ° C.

• The environment during cable laying should not be lower than 0 ℃.

• The bending radius during cable laying should not be less than the following regulations: single core cable -20 (D+d) mm/multi-core cable 15D+d) mm. D and d are the nominal outer diameter of the cable and the main conductor, respectively Diameter, mm).

Technical parameters

• Environmental temperature: 40 ° C for laying in the air; 25 ° C for buried laying.

• The working temperature of the cable conductor is 90 ° C.

• When the cable is buried underground, the soil thermal resistance coefficient g=1.0Cm/w, but the phenomenon of soil thermal resistance coefficient increasing due to moisture migration during long-term operation of the cable has not been considered. When laying cables underground, the distance between the cable axis and the ground is 1000mm.

• Multiple cables are laid in a flat manner, with the axis distance of the cables being S=2D.
