Description
Technical field
The utility model is related 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 conditions such as acidity, alkalinity, oiliness, low temperature, causes cable service life to be greatly reduced,
Environmental protection and energy saving project is carried out energetically by country now, has a vast market prospect, 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 cable long-term safety fortune
Capable development trend；
The easy aging of rubber, after rubber molecule combines a small amount of oxygen, the physical property that can make rubber is serious
Decline.Meanwhile heat can greatly improve the reaction rate between oxygen and rubber molecule；Temperature often increases 10 DEG C, reaction rate
It will double.When temperature is raised to 70 DEG C from room temperature, which has about 50 times of amplification.For mine
Cable cover(ing) is made of rubber material, is often exposed under sunlight and high temperature, therefore easily aging, is caused insulation breakdown, draw
Send out safety accident.
To overcome the shortcomings of use bending radius of current power cable is big, resistance to environment performance is poor, 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 electric system operation cost.
Utility model content
Purpose of utility model：In order to overcome the deficiencies in the prior art, a kind of highly-flexible adverse circumstances are provided and are used
Rubber set power cable.
Technical solution：The rubber set power cable that a kind of highly-flexible adverse circumstances described in the utility model use, including cable
Core, the cable core are twisted by more rubber sheath insulated cores；The gap filling and vulcanization rubber filling body of the cable core,
Silicon rubber inner sheath is externally provided in cable core, the wrapped shielding layer of copper wires outside silicon rubber inner sheath extrudes poly- outside shielding layer of copper wires
Ethylene insulating layer extrudes heat-resisting ethylene-propylene rubber outside polyethylene layer, steel-tape armouring layer is woven outside heat-resisting ethylene-propylene rubber, most
Afterwards, EPDM rubber oversheath is extruded in the outermost layer of cable, silicone tube is cased with outside EPDM rubber oversheath.
Further, the rubber sheath insulated core is by flexible flexible conductor, the EPDM being extruded in outside flexible flexible conductor
It rubber insulation, the Kapton being pasted onto outside ethylene propylene diene rubber insulating layer and is extruded in outside Kapton
It is 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 utility model are：
1st, using vulcanization rubber filling body, vulcanization rubber refers to the rubber vulcanized, is sticked with constant, is not easily broken and waits spies
Matter forms stereoeffect in raw rubber after vulcanization, have higher elasticity, heat resistance, tensile strength and in organic solvent
Indissolubility 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 high temperature resistance 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, the technology of insulation breakdown is caused 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）It crusts into porcelain, shape
Into stable entirety, oxygen is blocked to inside and outside realize.
Shielding layer of copper wires effectively can be accessed earth system in construction and installation, be additionally provided with steel band by the 5th, shielding layer of copper wires
Armor plays double layer screen, so as to achieve the effect that shielding interference signal and interference signal is passed to the earth.
6th, it is cased with silicone tube outside oversheath so that cable is pliable, and high anti-tear, resistance to kink, high temperature resistant, insulation performance is strong,
Elasticity is good, and sealing performance is excellent.
7th, ethylene propylene diene rubber insulating layer and the polyimides being pasted onto outside ethylene propylene diene rubber insulating layer are equipped in core
Film has prominent high temperature resistant, radiation hardness, resistant to chemical etching and electrical insulation capability, can for a long time make in 250~280 DEG C of air
With.
