Insulated steel tape armored cable

Cross-linked polyethylene insulated power cables feature high mechanical strength, good resistance to environmental stress, excellent electrical performance and chemical corrosion resistance. They are lightweight, have a simple structure and are easy to use. This product is applicable to transmission and distribution lines with an AC rated voltage of U0/U of 0.6/1kV and below.

The main feature of flame-retardant cables is that they are not prone to catching fire or, if they do, the ignition is limited to a certain range. They are suitable for places with a high density of cable laying, such as power stations, subways, tunnels, high-rise buildings, large industrial and mining enterprises, oil fields, and coal mines.

The main feature of fire-resistant cables is that they can not only transmit electricity under normal working conditions but also maintain normal operation for a certain period of time when on fire. They are suitable for places related to fire safety and fire rescue, such as nuclear power plants, subways, tunnels, and high-rise buildings.

Halogen-free low smoke flame retardant cables are characterized by not only flame retardant performance but also low smoke emission and harmlessness (with relatively low toxicity and corrosiveness). They are suitable for places with special requirements for cable flame retardancy, smoke density, toxicity index, etc., such as subways, hospitals, schools, tunnels, nuclear power plants, etc.
