Have an insulating layer, abutting on the outside of the insulating layer has wrapping layer, be filled with flexible filler in the wrapping layer, flexible filler with
Insulating layer abuts against, and is bonded with insulating layer on the outside of the wrapping layer, the insulating layer is fixedly connected with flame-retardant layer, the flame-retardant layer
Outside include tear resistant layer, the tear resistant layer outer surface is provided with flame retardant coating, the thickness of the flame retardant coating and tear resistant layer
For than 2:1.
Preferably, it is enclosed with weathering layer on the outside of the flame-retardant layer, the weathering layer includes polybutene layer, the polybutene layer
Inside be fixedly connected with waterproof layer, the thickness of the polybutene layer is greater than the thickness of waterproof layer.
Preferably, the number for leading core is five, and leads core and arrange in crosswise, and lead and mutually abut between core.
Preferably, the core of leading is copper core.
Preferably, the flexible filler is glass fabric.
The utility model proposes a kind of flame-retardant high-voltage cable, beneficial effect is: the design of flame-retardant layer, insulating layer, right
Cable plays the effect of fire-retardant thermal insulation, prevents cable in a fire, leads to the interruption of electric power, and the design of tear resistant layer enhances
The case where toughness of cable prevents cable from being worn out by hard object, causes electric leakage, the design of weathering layer enhances the weatherability of cable,
The case where preventing cable to be oxidized the breakage for leading to cable, cable is caused to leak electricity, is conducive to extend the service life of cable.
