Amount also grows with each passing day.In the power cable of various insulating forms, power cable with cross-linked polyethylene insulation be one show up prominently,
Booming new army, power cable with cross-linked polyethylene insulation electric property and heat resistance it is superior, connection and convenient transportation,
Oil-impregnated paper insulation, the power cable of polyvinyl chloride insulation structure have been instead of progressively at present.But due to high-tension cable conductor it is usual
Using structure is pressed, cause current-carrying capacity limited, potential safety hazard easily occur in poor using radiating effect for a long time, unstable properties,
Accordingly, it would be desirable to be improved to cable conductor, the performance of cable is improved.
Therefore, it is to solve the above problems, special that a kind of new technical scheme is provided.
The content of the invention
The present invention provides a kind of insulated cable structure.
The technical solution used in the present invention is:
A kind of insulated cable structure, from the inside to the outside successively include cable core, lapping layer, insulating barrier and external sheath layer, the cable core by
Multi beam leads core composition, leads core per beam and is formed by copper clad aluminum conductor and traction-resistant fibre are stranded, and multi beam leads core outer wrap wrapped
Layer, the gap that the lapping layer leads core with multi beam are provided with obturator, and the insulating barrier outer wrap has metal screen layer, described
Have nickel coated steel wire layer on the inside of insulating barrier, between the metal screen layer and oversheath, be provided with heat dissipating layer, the heat dissipating layer with it is outer
Space is left between restrictive coating and is supported by support bar.
Further, the insulating barrier adopts cross-linking polyethylene materials.
Further, the obturator is in bundle-shaped.
Further, the braiding layer is made up of TC.
Further, lead core to be formed by a copper clad aluminum conductor and two traction-resistant fibres are stranded per beam, lead between core per beam
It is arranged in parallel, leads per beam and be arranged in parallel between core and obturator.
The invention has the beneficial effects as follows:Simple structure, leads core and forms effectively using copper clad aluminum conductor and traction-resistant fibre are stranded
