What is the difference between fire-resistant cables and fireproof cables?

It is literally understood that "fire-resistant cable" is relatively resistant to combustion in the event of fire, and can usually maintain normal operation for at least 180 minutes at a flame temperature of 750 ~ 800 ° C.

Fireproof cable is to prevent fire burning, the selection of special materials made of seamless copper tube as a sheath, with magnesium oxide as insulation material production of fireproof cable, the common models are BTLY, YTTW, BBTRZ, HFTGB, BBTZ and so on. The experiment shows that: in 800 ~ 900℃ for 2 hours, the fireproof wire and cable still operates normally, and in 1000℃ for 30 minutes, it still continues to operate normally. It is similar to inorganic substances in a fire and cannot burn.

Fire-resistant cable is to add a layer of fire-resistant mica tape on the ordinary cable, and the "fireproof cable" is a mineral insulated cable, and the materials used between the two are completely inconsistent.

The fire-resistant characteristics of fire-resistant cables are mainly achieved by the fire-resistant mica tape between the conductor and the insulating layer. After the fire, a carbon shell will be formed between the mica and the insulation layer, which will conduct electricity when it encounters water, and will fall off when it is washed.

Mineral insulated cable will be ceramic at high temperature, protect the internal conductor, is the true sense of fire cable.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
