Abstract
The utility model discloses a kind of cable line insulating layers, it is characterised in that: the insulating layer includes the first base, insulating layer and the second base, and the first base, insulating layer and the second base are successively compound；The insulating layer is basalt fibre fabrics and the layers of two-sided for being coated on basalt fibre fabrics tow sides.Cable line insulating layer provided by the utility model is using basalt fibre and the chopped yarn of basalt fibre, basalt fibre be it is a kind of electrical isolation, corrosion-resistant, high performance fibre material resistant to high temperature, basalt fibre can increase the electrical insulating property and high temperature resistance of cable line insulating layer, and cable line insulating layer is enable to play better protective action.
Description
Technical field
The utility model relates to insulation applications, and in particular to a kind of cable line insulating layer.
Background technique
Cable line insulating layer is will to be electrically isolated from each other between core and the earth and out of phase core, guarantees electric energy
Conveying, is indispensable component part in power cable structure.But the cable line insulating layer insulation now occurred in the industry
Performance is inadequate, in face of some overload flows generate high temperature when, can not high temperature resistant, cause cable line insulating layer to lose insulation
Function causes electrical fire.
Utility model content
For it is above-mentioned in the prior art the technical issues of, the purpose of the utility model is to provide a kind of cable line insulating layers.
The purpose of this utility model is achieved through the following technical solutions.
A kind of cable line insulating layer, the insulating layer include the first base, composite layer and the second base, and the first base is answered
It closes layer and the second base is successively compound；
Composite layer is basalt fibre fabrics and the layers of two-sided for being coated on basalt fibre fabrics tow sides.
The layers of two-sided is the chopped yarn of basalt fibre and resin glue mixing material.
First base and the second base are the mixing material of rubber and the chopped yarn of basalt fibre.
The length of the chopped yarn of the basalt fibre is not more than 1mm.
The utility model has the following beneficial effects: cable line insulating layer provided by the utility model using basalt fibre and
Basalt fibre is chopped yarn, and basalt fibre is a kind of electrical isolation, corrosion-resistant, high performance fibre material resistant to high temperature, basalt
Fiber can increase the electrical insulating property and high temperature resistance of cable line insulating layer, so that cable line insulating layer is played preferably anti-
Shield effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1 is the first base, and 2 be composite layer, and 3 be the second base, and 4 be basalt fibre fabrics, and 5 be layers of two-sided.
Specific embodiment
As shown in Figure 1, a kind of cable line insulating layer, is used for protection of electrical cable, insulating layer includes the first base 1, answers
Layer 2 and the second base 3 are closed, composite layer 2 is basalt fibre fabrics 4 and is coated on 4 tow sides of basalt fibre fabrics
Layers of two-sided 5, the first base 1, layers of two-sided 5, basalt fibre fabrics 4, layers of two-sided 5 and the second base are compound according to 3 times.
Layers of two-sided 5 uses the chopped yarn of basalt fibre and resin glue mixing material, the basalt fibre in mixing material
Chopped yarn and resin glue will not generate chemical reaction, only physical bond, i.e., contain the chopped yarn of basalt fibre in resin glue.
First base 1 and the second base 3 are all made of the mixing material of rubber and the chopped yarn of basalt fibre.
The length of the chopped yarn of basalt fibre is not more than 1mm.
Other technologies are referring to the prior art.
The above is only preferred embodiments of the present invention, is not the limit to technical solutions of the utility model
It is fixed, it is noted that those skilled in the art can also make further under the premise of technical solutions of the utility model
Improvement and change, these improvement and change should all be covered within the protection scope of the present utility model.
