Abstract
The utility model discloses a polyvinyl chloride sheath high tension cable, including cable core, armor, shielding layer and the polyvinyl chloride restrictive coating that sets gradually from inside to outside, be provided with a plurality of conductors in the cable core, the surperficial cladding of conductor has the insulating layer, the conductor is centering on the even range in the centre of a circle of cable core in the cable core, be connected with the insulating rod between two adjacent conductors, be provided with the triangle -shaped insulation support frame in the cable core. The utility model discloses not only conductor position inside the cable core is very stable, has prevented conductor contact to cable core inner wall, moreover wrapped insulating layer on the conductor for the conductor is because skin effect can take place for high frequency current, and the higher temperature on conductor surface is fallen by the most isolation of insulating layer, thereby it can not influence the oversheath of cable to make the conductor take place skin effect, thereby has prolonged the life of oversheath, has guaranteed the safe handling that high tension cable can be steady in a long -term.
Description
Technical field
This utility model is related to field of cables, and in particular to a kind of pvc sheath high tension cable.
Background technology
Existing high tension cable is mostly stranded as conductor, during power transmission, high frequency using naked copper or tin-coated copper
Electric current can occur Kelvin effect, cause the temperature of peripherally located conductor and can drastically raise, it is possible to can damage the outer layer of cable,
Even fire is caused, and position of the conductor of existing high tension cable inside cable core is not very stable, in the effect of external force
Under be squeezed and easily lead to conductor position and change, some meetings are moved to is close to cable core inwall so that conductor periphery
Higher temperature be very easy to be delivered to oversheath, the safety of the service life and high tension cable that have had a strong impact on oversheath makes
With.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, there is provided a kind of conductor is stable in cable core internal structure
And the good pvc sheath high tension cable of insulated heat performance of conductor.
Technical scheme：For achieving the above object, this utility model provides a kind of pvc sheath high tension cable, including by
Cable core, armor, screen layer and the pvc sheath layer for setting gradually from inside to outside, is provided with some conductors in the cable core,
The Surface coating of the conductor has insulating barrier, and the conductor is uniformly arranged in cable core around the center of circle of cable core, the phase
Insulating bar is connected between two adjacent conductors, triangle insulating carriage, the triangle insulation are provided with the cable core
Three angles end of bracing frame is both connected on conductor, and the insulation fill stratum in filling cable core space is additionally provided with the cable core.
Design principle of the present utility model is：By the coated insulation layer on conductor so that conductor is because high frequency electric meeting
Generation Kelvin effect, the higher temperature of conductive surface is isolated out by insulating barrier major part, in addition the setting of insulation fill stratum and energy
Enough further transmission for hindering temperature, between two adjacent in addition conductors insulating bar is connected with, so as to prevent conductor with
Come in contact between conductor, it is therefore prevented that heat transfer, one entirety of arrangement form of conductor, triangle occur between conductor and conductor
Insulating carriage can improve the stability of conductor, prevent conductor from significantly displacement occurring in cable core, it is to avoid conductor contact
Accelerate heat transfer to cable core inwall.
Further, the conductor rounded matrix arrangement in cable core.
Further, the center of circle of the center of circle of the circular matrix that the conductor is formed and cable core overlaps.
Further, the armor is aluminium strip lock armo layer.
Further, the insulating barrier is insulating oil enamelled coating.
Beneficial effect：Compared with prior art, not only conductor is highly stable in cable core interior location, prevents for this utility model
Conductor touches cable core inwall, and coated insulation layer on conductor so that conductor because high frequency electric can occur Kelvin effect,
The higher temperature of conductive surface is isolated out by insulating barrier major part, so that conductor occurs Kelvin effect does not interfere with cable
Oversheath, so as to extend the service life of oversheath, it is ensured that the safe handling that high tension cable can be steady in a long-term.
