Into, it can not only play a part of shielding core, and the softness required by cable is met, that improves cable uses the longevity
Life.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model is by setting water blocking layer to be made using ethylene-propylene copolymer elastomer and water-proofing powder by processing
Into water blocking expanding powder, by process meanses make its surface band toughness, allow its firmly adsorb core protect
Each layer surface of layer, the expanding powder that blocks water formed have preferable water-swellable performance, when the infiltration of core protective layer be block water it is swollen
Swollen powder can expand rapidly, block water and penetrated into core protective layer, and the structure blocks water, and expanding powder spraying is uniform, and block-water performance is good,
Vi have high safety.
2nd, the utility model is by setting resistance to breakdown layer to be made up of polyacrylonitrile fibre material, to prevent cable
Electrostatic Treatment, improves the performance of cable itself antistatic, sufficiently avoids the generation of cable internal electrostatic phenomenon, can prevent
Cable is broken down by high-voltage, and improves the pressure-resistant performance of cable, and so as to extend the service life of cable, and the polyacrylonitrile is fine
The durability of dimension material is higher, good pressure-resistant performance, and soft texture, is greatly improved the pliability of cable.
3rd, by setting restrictive coating, using polyurethane TPU elastomers as material, such a material can repeat back to the utility model
Receive and utilize, greatly save resource, can adapt to some high salinities and the special adverse circumstances such as difference variation is bigger, this practicality
The new water blocking layer by setting, the moisture for preventing device from penetrating into enter, and realize the drying of internal environment, ensure that work can be suitable
Profit is carried out.
