Description
Technical field
The present invention relates to field of cables, and in particular to the rubber set power cable that a kind of highly-flexible adverse circumstances use.
Background technology
At present, power cable conductor is mostly solid structure, and flexibility is poor, and insulation, sheath are crosslinked polyethylene, polychlorostyrene second
Alkene material, using easy to aging under the environmental condition such as acidity, alkalescence, oiliness, low temperature, cable service life is caused to be greatly reduced,
Environmental protection and energy saving project is carried out energetically by country now, has wide market prospects, determines the predominantly cable of cable service life
The aging of nonmetallic materials in structure, the ageing properties for changing nonmetallic materials in the construction of cable are to meet that cable long-term safety is transported
Capable development trend；
The easy aging of rubber, after rubber molecule combines a small amount of oxygen, the physical property degradation of rubber can be made.
Meanwhile heat can be greatly enhanced the reaction rate between oxygen and rubber molecule；Temperature often raises 10 DEG C, and reaction rate will carry
Double.When temperature is raised to 70 DEG C from room temperature, the reaction rate has about 50 times of amplification.Cable protection for mine
Set is made using elastomeric material, is often exposed under sunlight and high temperature, therefore easily aging, causes insulation breakdown, triggers safety
Accident.
The shortcomings of to overcome the big use bending radius of current power cable, resistance to environment performance difference, and according to electric power
Department and the demand in market, we start to develop development using flexibility more preferably, resistance to environment performance is more excellent, longtime running more
The power cable of the features such as safe, service life greatly improve, and substantially reduce power system operation cost.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, there is provided the rubber that a kind of highly-flexible adverse circumstances use
Cover power cable.
Technical scheme：The rubber set power cable that a kind of highly-flexible adverse circumstances of the present invention use, including cable core, institute
The cable core stated is twisted by more rubber sheath insulated cores；The gap filling and vulcanization rubber filling body of described cable core, in cable
The outer silicon rubber inner sheath of core, wrapped shielding layer of copper wires, extrudes polyethylene insulation outside shielding layer of copper wires outside silicon rubber inner sheath
Layer, extrudes heat-resisting ethylene-propylene rubber outside polyethylene layer, steel-tape armouring layer is woven outside heat-resisting ethylene-propylene rubber, finally, in electricity
The outermost layer of cable extrudes EPDM rubber oversheath, and silicone tube is cased with outside EPDM rubber oversheath.
Further, described rubber sheath insulated core is by flexible flexible conductor, the EPDM being extruded in outside flexible flexible conductor
Rubber insulation, the Kapton being pasted onto outside ethylene propylene diene rubber insulating barrier and it is extruded in outside Kapton
Formed into porcelain type fire retardant polyolefin sheath.
Further, the wire is zinc-plated copper wire.
Compared with prior art, the beneficial effects of the present invention are：
1st, the rubber that vulcanized is referred to using vulcanization rubber filling body, vulcanization rubber, has constant glutinous, the speciality such as be not easily broken,
Stereoeffect is formed after vulcanization in rubber, there is higher elasticity, heat resistance, tensile strength and in organic solvent not
Dissolubility etc..
2nd, using silicon rubber inner sheath so that cable has good heat resistance, cold resistance, weatherability, electric conductivity, heat conduction
Property, radiation resistance, high flame retardant, good permeability.
3rd, oversheath improves heat resistance using through silicone-modified EP rubbers, and adding antioxidant makes through polysiloxanes
The resistance to elevated temperatures of modified ethylene propylene diene rubber further improves, and 125 DEG C can be reached with the temperature of long-term work, minimum laying
Temperature be -40 DEG C, solve in the prior art for mine cable cover(ing) easily aging, cause the technology of insulation breakdown to ask
Topic.
4th, core is externally provided with into porcelain type fire retardant polyolefin sheath, can be in flame low temperature（400 DEG C or so）Crusted into porcelain, shape
Into stable entirety, oxygen is blocked to inside and outside realize.
5th, shielding layer of copper wires, shielding layer of copper wires effectively can be accessed earth system in construction and installation, is additionally provided with steel band
Armor, double layer screen is played, the effect of the earth is passed to so as to reach shielding interference signal and interference signal.
6th, it is cased with silicone tube outside oversheath so that cable is pliable, and high anti-tear, resistance to kink, high temperature resistant, insulating properties are strong,
Elasticity is good, and sealing property is excellent.
7th, ethylene propylene diene rubber insulating barrier and the polyimides being pasted onto outside ethylene propylene diene rubber insulating barrier are provided with core
Film, there are prominent high temperature resistant, radiation hardness, resistant to chemical etching and electrical insulation capability, can make for a long time in 250~280 DEG C of air
With.
