Tension, is difficult the polyethylene insulation water repellent electric cable being broken off.
To achieve these goals, the technical solution used in the present invention is such：The polyethylene insulation of the present invention blocks water
Cable, including polyethylene layer, polyethylene layer Surface coating has high-abrasive material structure sheaf, and high-abrasive material structure sheaf seals
It is connected on polyethylene layer, in polyethylene layer, is provided with plastic layer, plastic layer is fixed on polyethylene layer, its bag
Cover a water blocking layer setting, water blocking layer is connected with plastic layer by a fire prevention cotton thread, is provided with compression-resistant material structure sheaf, resists in water blocking layer
Pressure material structure layer more than one, it is interspersed between multiple conductors, and conductor is fixed on water blocking layer.
Further, as a kind of specific version, water blocking layer of the present invention manufactures cloth and height by polyester fiber
Absorbent material is composited.
Further, as a kind of specific version, between plastic layer of the present invention and water blocking layer, it is filled with resistance
Water yarn, water blocking yarn is fixed on plastic layer and water blocking layer.
Further, as a kind of specific version, compression-resistant material structure sheaf of the present invention adopts asbestos bodies to tie
Structure.
Further, as a kind of specific version, high-abrasive material structure layer surface of the present invention is provided with several
Projection, projection is integrally attached on high-abrasive material structure sheaf.
Further, as a kind of specific version, in high-abrasive material structure sheaf of the present invention includes being arranged on
The soft steel wire in portion and the abrasive rubber structure being coated on outside soft steel wire.
Compared with prior art, it is an advantage of the current invention that：The polyethylene insulation water repellent electric cable of the present invention, not easy to wear,
There is multilamellar protection, tension, be difficult to be broken off, the life-span increases significantly, electric leakage can be effectively prevented, safety coefficient carries significantly
Height, meanwhile, low cost, intensity height, good water-proof effect and long service life.
