Background technology
With the continuous maturation of China's Power-line technology, national is continued to develop, and the demand to electric wire is also continuously increased, so that
Requirement more and more higher of the people to electric wire, the electric wire of prior art is mainly using polyvinyl chloride insulation layer, and its environmental-protecting performance is poor, material
Material is not soft enough, and the electric wire of existing technology its performance does not reach the requirement of people, limited mechanical strength, thus limits
Stability and the feature of environmental protection that electric wire is used, practicality are restricted, therefore, it is proposed that a kind of copper core polyvinyl chloride insulation is twisted
Type connection cord.
Utility model content
The purpose of this utility model is to provide a kind of copper core polyvinyl chloride insulation strand type connection cord, with solution
State the problem of material proposed in background technology is not soft enough.
To achieve the above object, the utility model provides following technical scheme：A kind of copper core polyvinyl chloride insulation strand type connects
Connect and use cord, including core, the outer wall of the core is provided with insulating barrier, and the outer wall of the insulating barrier is provided with elastic caoutchouc
Layer, the cavity formed between the insulating barrier and elastic rubber layer is provided with phenol formaldehyde foam packed layer, the elastic rubber layer
Outer wall is socketed with soft layer, and the soft layer includes braiding layer, and the outer wall of the braiding layer is socketed with eleatrical insulating board, the electricity
The outer wall of insulating board is socketed with fibrous layer, and the outer wall of the soft layer is socketed with polyvinyl chloride insulation layer, the polyvinyl chloride
The outer wall of insulating barrier is socketed with wearing layer.
It is preferred that, the outer wall of the insulating barrier is provided with polyester film.
It is preferred that, the braiding layer, eleatrical insulating board and fibrous layer are integrated connection.
It is preferred that, the wearing layer is highly-chlorinated polyethylene sleeve.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple and compact for structure, substantially reduces
Production cost, good insulation preformance, with higher heat-resistant aging and corrosion resistance, it may have excellent anti-flaming performance, can
Increase service life, can also greatly improve the flexibility and folding resistance of electric wire.
