Fireproof wire

The utility model discloses a fireproof wire, including the sinle silk that is used for conducting the signal of telecommunication, and the cladding is in being used for outside the sinle silk prevents the rubber insulation layer of electric wire burning and conduction kindling material, the rubber insulation layer is the pottery silastic -layer, the sinle silk outside lies in the sinle silk with be provided with outward around the covering between the rubber insulation layer, outer is a flame retardant coating that is formed around the package by inorganic material fire -resistant area around the covering, the outside cladding on rubber insulation layer has and is used for preventing the potteryization back the cracked screen panel layer that drops in rubber insulation layer. This scheme effectively improves the fire resistance of electric wire through setting up the pottery silastic -layer and forming double -deck fire resisting construction around a covering outward around what the package formed by inorganic material fire -resistant area. Through setting up pottery silastic -layer and screen panel layer, prevent effectively that the burning things which may cause a fire disaster from stretching along the electric wire, avoid the rubber insulation pull -up after the potteryization to fall simultaneously, guarantee that the pottery silastic -layer forms the sinle silk and last the protection.
