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
