Description
Technical field
The utility model relates to technical field of electric wires and cables, more particularly to a kind of antiacid alkali heat proof cable.
Background technique
Wires and cables industry is the second largest industry that China is only second to automobile, and product variety satisfaction rate and domestic market are occupied
Rate is more than 90%.Worldwide, Chinese gross output value of wire and cable has been more than the U.S., becomes the first big electric wire electricity in the world
Cable producing country.With the rapid development of china's wire and cable industry, creation of new enterprise quantity constantly rises, and industry overall technology is horizontal
It is largely increased.
Since the application range of cable is very extensive, cable can use in various rugged environments, such as acid, alkali
In the environment such as property, high temperature, the general anti acid alkali performance energy of existing cable and high temperature resistance are poor, make in these adverse circumstances
Used time cable is easy to aging, and service life is caused to greatly shorten.
Utility model content
It is heat-resisting to provide a kind of antiacid alkali for the shortcomings that technical problem to be solved in the utility model is, overcomes the prior art
Cable.
In order to solve the above technical problems, the technical solution of the utility model is as follows:
A kind of antiacid alkali heat proof cable is socketed on the outside of the cable core including the cable core that several wire core is twisted
Insulating layer offers a heat release hole on the insulating layer, is provided with buffer layer on the outside of the insulating layer, if the buffer layer includes
The dry cylindrical bump being uniformly arranged, the axis of the cylindrical bump are parallel to the axis of cable core, the buffer layer outside
It is socketed with anti-corrosion layer.
Further, for the heat release hole at least provided with three groups, heat release hole described in every group includes several along cable length
The evenly distributed heat release hole in direction.
A kind of preceding antiacid alkali heat proof cable, anti-corrosion layer outside are socketed with thermal insulation layer.
A kind of preceding antiacid alkali heat proof cable, thermal insulation layer outside are socketed with sheath.
A kind of preceding antiacid alkali heat proof cable, anti-corrosion layer are made of polytetrafluoroethylene (PTFE).
A kind of preceding antiacid alkali heat proof cable, thermal insulation layer are made of glass fibre.
The beneficial effects of the utility model are:
(1) multiple cylindrical bumps are arranged in the utility model on the buffer layer, make to be formed between insulating layer and buffer layer empty
Gap, and multiple groups heat release hole is offered on the insulating layer, it is connected to cable core with gap, the heat that cable core generates when working can be by dissipating
Hot hole is expelled in the gap between insulating layer and buffer layer, is then radiated by gap, and dissipating for cable is effectively increased
Hot property；Meanwhile the impact that the also absorbable cable of buffer layer is subject to, avoid percussion from impacting to cable core to cable core；
(2) the utility model is socketed with anti-corrosion layer outside buffer layer, has good anti acid alkali performance, avoids cable in acid
Corroded in property or alkaline environment, improves the application range of cable, extend the service life of cable；
(3) the utility model is socketed with thermal insulation layer outside anti-corrosion layer, and the high temperature of Exterior cable is avoided to be transmitted at cable core,
Make cable core that can keep the operating temperature for being more suitable for, improves the heat resistance of cable；
(4) the utility model is socketed with sheath outside thermal insulation layer, as the outermost layer protective layer of cable, protects to cable
Shield avoids cable from being scratched by sharp object, further extends the service life of cable.
