Abstract

The utility model discloses a tin-coated copper wire armored sheath and a power cable comprising main wired cores, a ground wire core, an insulation shielding layer, a steel-band armored polyethylene sheath layer and a tin-coated copper wire armored sheath layer, wherein two sets of main wired cores, one ground wire core and an aluminum alloy conductor drainage wire are extruded in the insulation shielding layer, the insulation shielding layer is wrapped up by the steel-band armored polyethylene sheath layer, and the steel-band armored polyethylene sheath layer is wrapped up by the tin-coated copper wire armored sheath layer. The tin-coated copper wire armored sheath and the power cable are excellent in conductive performance and aging resistance, multiple armored sheath layers of the cable provided enhance the pull resistance of the power cable, improve the wear resistant performance of the power cable, and prolong the service lifetime. The tin-coated copper wire armored sheath and the power cable are suitable for the aviation, electric power, metallurgy and tunnel fields.

Description

A kind of tinned copper wire armouring sheath and power cable

Technical field

The utility model belongs to field of cables, relates in particular to a kind of tinned copper wire armouring sheath and power cable.

Background technology

At present, along with Chinese society expanding economy, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in the fields such as aviation, electric power, metallurgy and tunnel, to the electric conductivity of cable, anti-wear performance and resistance to ag(e)ing aspect and security reliability aspect, require all high especially.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of tinned copper wire armouring sheath and power cable with good anti-wear performance and resistance to ag(e)ing.

The utility model takes following technical scheme to realize: a kind of tinned copper wire armouring sheath and power cable, it is comprised of master core, ground connection core, insulation screen, steel-tape armouring pe sheath layer and tinned copper wire armouring restrictive coating.In described insulation screen, be extruded with two groups of master cores, a ground connection core and an aluminium alloy conductor drainage thread, described insulation screen is wrapped with one deck steel-tape armouring pe sheath layer, and described steel-tape armouring pe sheath layer is wrapped with one deck tinned copper wire armouring restrictive coating.

Described master core is from inside to outside successively by aluminium alloy conductor and be wrapped in perfluoroethylene-propylene insulating barrier outside aluminium alloy conductor and ethylene propylene rubber insulated layer forms.

Described ground connection core is from inside to outside successively by copper conductor and be wrapped in tinned copper wire screen outside copper conductor and ethylene propylene rubber insulated layer forms.

In described steel-tape armouring pe sheath layer, be provided with a heating wire.

The utlity model has in sum following beneficial effect: the utlity model has good electric conductivity and resistance to ag(e)ing;

The multilayer armouring restrictive coating of cable arranges, and can strengthen the pull resistance of cable, improves the anti-wear performance of cable, increases the service life;

Master core adopts dielectric layers, strengthens the insulation property of master core, improves the electric conductivity of cable.
