Applies to power-generated stations, subway tunnels, high-storey buildings, large-size factory and mines, oil field and so on.

Main features of flame-retardant power cables is hard to get fire of that continuous burning of cables is very limited when it is on fire

Applies to power-generated stations, subway tunnels, high-storey buildings, large-size factory and mines, oil field and coal mines with many cables laid tightly together

Long-term working temperature of cable should be not higher than 70 degrees Celsius

When core is in short-circuit, temperature should not exceed 160 degrees Celsius

While installation ambient temperature should not be lower than o degrees Celsius and bending radius should not be less than 10 times of outer diameter

Flame-retardant cable is plus ZA, ZB or ZC before type of common power cable

Type of fire resistance cable is plus ZAN, ZBN or ZCN before type of common power cable
