Description

Glass fiber mica fire-resistant wire

Technical Field

The utility model relates to the field of refractory wires, in particular to a glass fiber mica fire-resistant wire.

Background

The fire-resistant wire is a cable which can be safely allowed for a certain time in the case of flame combustion. The fire-resistant wire is widely applied to places related to fire protection safety and fire protection lifesaving, such as high-rise buildings, underground railways, underground streets, large power stations, important industrial and mining enterprises and the like.

The common lead uses PVC material as insulating material, but the fire resistance is poor, when a fire disaster occurs, the PVC material is easy to burn, and when the fire disaster occurs, a large amount of smoke can be released, and the smoke contains a large amount of toxic gas, so that the human body is greatly injured. Glass fiber is a good insulating material, and can be considered as an insulating material of a wire.

The mica tape has good high temperature resistance and combustion resistance, and basically no volatilization of harmful smog exists when the mica tape burns on open fire.

In order to study a high-performance heat-resistant wire, a wire mainly using a glass fiber material and a mica material was developed.
