To achieve the above object, the utility model provides following technical scheme：A kind of high pressure rubber cable, including cable sheet Body and filler, the cable body are by conductor, insulating barrier, heat-insulated rod, heat insulation glass cotton layer, filler successively from inside to outside With external rubber sleeve composition, the conductor is provided with 3 groups, and conductor is distributed in cable core belting layer in equilateral triangle, described to lead Insulating barrier is provided with outside body, and insulating barrier is cladded with and is stamped internal shield, the internal shield external stability has heat insulation glass cotton Heat insulating coatings layer is scribbled on layer, and heat insulation glass cotton layer table wall, the heat insulation glass cotton layer external stability has heat-insulated rod, and External shielding layer is provided with the outside of heat-insulated rod, the filler is covered in outside external shielding layer, and cable core is provided with outside filler Belting layer, the cable core belting layer external stability has is provided with external rubber sleeve on the outside of interior rubber sheath, and interior rubber sheath.

It is preferred that, the conductor is made up of steel-cored aluminium strand component.

It is preferred that, the insulating barrier is mica tape.

It is preferred that, the hot thermal insulation coatings layer is composite aluminium-magnesium-silicate insulating moulding coating.

It is preferred that, the filler center is provided with tensile reinforcement member, and filler is by glass fiber material members system Into.

It is preferred that, the external shielding layer and internal shield are that polymer semiconductor shielding material component is made.

Compared with prior art, the beneficial effects of the utility model are：The insulation of equipment mineral wool layer and heat-insulation and heat-preservation are applied Material can play multi-level, efficient heat-blocking action to conductor so that conductor possesses fabulous heat-proof quality in itself, heat-insulated rod Setting can prevent from coming in contact between conductor and conductor, can not carry out heat transfer by heat-insulated rod between conductor and conductor, make Temperature can not be passed to other conductors by obtaining the higher conductor of temperature, so as to effectively control the bulk temperature and electricity of cable core The temperature of cable outer layer, it is ensured that the working temperature environment of cable outer layer, not only increases the security that cable is used, and extension The service life of cable.
