What Flame-retardant Cable?

- Dec 18, 2018-

 The flame-retardant cable describes the cable that is buried underneath the specified test conditions. After the actual test fire source is eliminated, the flame spreads only inside the limited range, and the residual flame or residual burn could be self-extinguished within a limited period. Its fundamental characteristic is that it might be burnt out in case of a fire and cannot run, but it can prevent the actual spread of fire. In layman's conditions, if the cable is inside a fire, it can limit the combustion to some local extent, without spreading, and keep other equipment to prevent further losses.


 1. Structural features of flame retardant cable

 The structure of the flame-retardant cable is basically just like that of the ordinary cable, except how the insulating layer, the sheath, the outer sheath and also the auxiliary material is all or partially made from a flame-retardant material.


 2. Category of flame retardant cables

 Based on the different flame retardant materials associated with cables, flame retardant cables tend to be divided into two categories: halogen-containing flame-retardant cables as well as halogen-free low-smoke flame-retardant cables.
