Description
Technical field
This utility model relates to technical field of cable production, particularly belongs to a kind of compound insulated cable.
Background technology
Rubber insulation mining conveying mechanical cable is to use for the power supply that mine scraper or similar devices are supporting
Cable, need to frequently move during use, therefore to bending, wear-resisting, punching press and torsion, especially has higher requirement to tensile property.
For mine cable product, along with mining machinery producing capacity and the raising day by day of place capacity, cable is used directly to power
Scraper obtain substantial amounts of selection, therefore, the consumption of the rubber insulation mine cable of the type is the most increasing.Due to ore deposit
The working environment of mountain mechanical cable is extremely severe, and when unwrapping wire that mining conveyor tool is in operation or take-up, cable will be by ore deposit
The friction of stone even hinders, so that cable is at work frequently by severe friction, punching press and big intensity pulling force and torsion,
Comdemning period is the shortest, need to be replaced as frequently as, and long period of soaking is in water sometimes, and cable must have good block-water performance, with
Time darkness wet spaces often occur that Mus worm and Coptotermes formosanus Shtrari. gnaw cable, cause cable fault.
Utility model content
For the problems referred to above, the purpose of this utility model there is provided a kind of compound insulated cable, reasonable in design, electricity
Cable entirety tensile property is superior, has preferable waterproof heat-resisting performance, it is possible to ensures good communication, meets actually used need
Ask.
The technical solution adopted in the utility model is as follows:
A kind of compound insulated cable, including cable core and oversheath, described cable core is sequentially provided with cable core band from inside to outside
