Flame retardant wire refers to the cable that under specified test conditions, the sample is burned, and after removing the test fire source, the flame spreads only within a limited range, and the residual flame or residual burn can extinguish itself within a limited time. This wire has the function of blocking and delaying the spread of the flame along the wire and cable, so that the fire does not expand. Flame retardant wires are widely used in places with high fire safety requirements, such as building decoration lighting transmission and distribution, control, alarm, fire protection system product lines.

The basic characteristic of the flame retardant wire is that it may be burned out and not run in the case of fire, but it can prevent the spread of the fire. Generally speaking, in case of fire, the cable can limit the combustion to a local scope, do not produce spread, save other various equipment, to avoid causing greater losses. The basic characteristics of flame-retardant cable include: under the flame temperature of 350 ° C ~ 800 ° C, the cable can operate normally; In the case of flame barbecue, the cable will not be burned, and can maintain normal operation for a certain time; In the case of flame barbecue, the insulation layer of the cable will not drip, to avoid triggering the burning of other items.

Flame retardant wire is divided into ordinary flame retardant wire, flame retardant refractory wire, halogen-free low smoke flame retardant wire and other categories. These wires use special materials and structural design, when subjected to fire sources, can reduce the production of flame, smoke and toxic gases, effectively prevent the spread of fire, and maintain the normal work of the wires.

It should be noted that the flame retardant wire is not a wire that does not burn at all, but can prevent the spread of the fire to a certain extent when the fire occurs, and buy time for personnel evacuation and fire fighting. Therefore, when using flame retardant wires, it is still necessary to strictly abide by the relevant safety regulations to ensure the safe operation of wires and cables.

The flame-retardant wire can maintain normal operation at the flame temperature mainly due to its special material and structural design. These wires are made of a flame retardant material that has high temperature stability and fire resistance to maintain wire integrity and insulation in the event of a flame barbecue.

In addition, the flame retardant wire also uses a special structural design, such as increasing the thickness of the insulation layer, the use of high temperature filler, etc., to improve the fire resistance of the wire.

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.
