Furthermore, in the flame-proof cable, the insulating layer is replaced with a thermoplastic elastomer (TPE) for the perfluoroethylene propylene copolymer (FEP).

Furthermore, in the flame-proof cable, the conductor is a tinned copper wire.

The advantage of the new type is that through the heat resistance of the insulating layer, the oxidation resistance of the shielding layer and the flame-retardant coated conductor of the flame-retardant braided layer, the new type can not only operate normally in a high temperature environment, but the wire is also resistant. High temperature and flame retardant effect; and the insulating layer can replace perfluoroethylene propylene copolymer (FEP) with thermoplastic elastomer (TPE), and can also achieve high temperature resistance and flame retardant effect.
