Preferably, the Anti earth quake ball is distributed in the inside of shakeproof layer in a manner of annular array.
Preferably, the heat-insulating flame-retardant layer includes glass layer, asbestos layer, polyethylene layer, flame retardant rubber layer and the flame retardant plastic bed of material, and glass layer, asbestos layer, polyethylene layer, flame retardant rubber layer and the flame retardant plastic bed of material are set gradually from outside to inside.
Preferably, the oversheath is made up of Ceramic silicon rubber.
Preferably, the thickness ratio of the insulating barrier, screen layer, heat-insulating flame-retardant layer and flame retardant coating is 1:1:1:1.
Compared with prior art, the beneficial effects of the invention are as follows：The fire-retardant electric power protecting pipes of the PE, pass through the design of insulating barrier, serve the effect of insulation, avoid electric wire electric leakage and the generation of electric shock accidents occurs, pass through the design of heat-insulating flame-retardant layer, in the event of a fire, fire-retardant effect can be played, avoid the intensity of a fire and the more burn the more prosperous, prevent the sprawling of the intensity of a fire, also protecting the electric wire of inside simultaneously will not be damaged, pass through the setting of shakeproof layer, avoid protecting pipe and situation about deforming occur because weight pounds, pass through the setting of flame retardant coating, can allow protecting pipe can for a long time high temperature resistance and occur without damage, pass through the setting of damp-proof layer, there is situation about corroding in the inside for avoiding protecting pipe.
