Most of the wire and cable people usually buy are ordinary cables, some places use high-voltage cables or fire-resistant cables, today, wire and cable to share with you is flame retardant cable: flame retardant cable will not be burned?



When there is a fire in the wire and cable, the flame retardant cable can limit the burning to a local scope, prevent the spread, retain other various equipment, and avoid greater losses.

Flame-retardant cable is a new type of cable with flame-retardant performance developed in recent years according to the actual needs of production, which is suitable for the occasions of fixed flame-retardant requirements of power transmission and distribution system. Such as: cable tunnel, cable sandwich, main control room, command center and other important occasions.

The structure of the flame-retardant cable is the same as that of the ordinary cable, without difference. In terms of materials used, in addition to changing the wrapping tape used in the cable to flame retardant tape and changing the PVC sheath material used in the outer sheath to PVC flame retardant sheath material, all the rest are changed to ordinary cables of the corresponding model.

According to the test specifications and requirements of the flame retardant performance of the cable, flame retardant cable in the combustion process, the flame temperature is greater than 815℃, the fire time 40min, its requirements are: stop the fire, the combustion should be extinguished naturally, and then wipe the sample, ignore any non-metallic material softening and deformation, the sample carbonization (combustion) length shall not exceed 2500mm.

It shows that the flame-retardant cable has the characteristics of small burning range in case of fire and self-extinguishing from fire. It's not that fireproof cables won't burn.

When the conductor flows through the conductor, it generates heat due to the presence of conductor resistance, which is called the thermal effect of current.

Due to the thermal effect of the current, various heating appliances can be made, such as: electric furnace, welding machine, oven, electric soldering iron, iron, etc., which are conducive to the thermal effect of the current. But in many cases, the thermal effect of the current is harmful.

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.
