Description
Technical field
The present invention relates to the cable in a kind of power pipe.
Background technology
At present, with the development of electric utility, the scope laying of electric power network is increasingly wider, and electric wire consumption increases rapidly
Long, the quality requirement to cable is also constantly improved, such as electric conductivity to cable, wear-resisting in the cable of provided underground
Performance and resistance to ag(e)ing aspect and security reliability aspect require all especially high.
The content of the invention
The invention provides the cable in a kind of power pipe, it can not only strengthen the pull resistance of cable, improve cable
Anti-wear performance, increase the service life.
Present invention employs following technical scheme：A kind of cable in power pipe, it includes that the cable includes conductor
Core and insulating barrier, the insulating barrier include inner insulating layer and external insulation layer, and the inner insulating layer is located at the outside of external insulation layer,
Cable skeleton is provided between inner insulating layer and external insulation layer, conductor cores are provided with inner insulating layer, inner insulating layer and conductor cores it
Between formed by sintering, hot pressing and seamless treatment.
Glass layer is provided between described inner insulating layer outside and cable skeleton.Described cable skeleton is compiled for copper wire
Knit and form.Described external insulation layer is polythene material.Described inner insulating layer is silica gel sheath.Each heart yearn of described conductor cores
Between square distribution.Packed layer is provided between each heart yearn of described conductor cores, packed layer is filled for fire resistant ceramic powder
Layer.
The invention has the advantages that：After employing above technical scheme, cable of the present invention is including conductor cores and absolutely
Edge layer, the insulating barrier includes inner insulating layer and external insulation layer, and the inner insulating layer is located at the outside of external insulation layer, in interior insulation
Cable skeleton is provided between layer and external insulation layer, conductor cores are provided with inner insulating layer, passed through between inner insulating layer and conductor cores
Sintering, hot pressing and seamless treatment are formed, and so can not only increase the intensity of cable, and with the effect being fully sealed, together
When dielectric strength increase.The present invention is provided with cable skeleton, can thus strengthen the pull resistance of cable, improves the wear-resisting of cable
Performance, increases the service life, and master core uses dielectric layers, strengthens the insulating properties of master core, improves the electric conductivity of cable
Energy.Of the invention 4, it is polythene material according to external insulation layer, described inner insulating layer is silica gel sheath, and that so not only improves is anti-ageing
Change performance, strengthen service life, and prevent from damaging heart yearn.Square distribution between each heart yearn of conductor cores of the present invention, leads
Packed layer is provided between each heart yearn of body core（7）, packed layer is fire resistant ceramic powder packed layer, so can not only improve cable
Stability, and with good fire resistance.
