Abstract
The utility model discloses a high temperature resistant, silicone rubber insulating control cable having silicone rubber sheaths, comprising a core group composed of more than one cores. Each of the cores is sequentially composed of a core conductor and an insulating layer from inside to outside. The control cable is characterized in that the core group is provided with a steel band armor on the periphery, the inner side of the steel band armor is also provided with a belting inner lining layer, and the exterior of the steel band armor is provided with an outer sheath; and the insulating layer and the outer sheath are formed by extruding silicon rubber material. The steel band armor is formed by lapping inner and outer layer steel bands on the inner lining layer with butt gaps in a leftward spiral manner, wherein the middle of the outer layer steel band is substantially above the gap of the inner layer steel band, and the butt gap should be no more than 50% of the width of the steel bands. Since the insulating layer, the inner sheath and the outer sheath are made of silicone rubber material, the control cable has high insulating property, and high temperature resistance, and is suitable for occasions having a high temperature up to about 180 DEG C; and because of the structure of the steel band armor, the cable has enhanced anti-compression capability and electromagnetic shielding function.
Description
Technical field
The utility model relates to a kind of cable, specifically is a kind of high-temperature-resisting silicon rubber electrically insulating silicone rubber sheath control cable cable.
Background technology
Control, signal wires cable are as the connecting line between each electric appliances, instrument and the automatics; Be mainly used in important events such as control loop and protection circuit; Play various effects such as transmitting control, signal, be widely used in enterprises such as iron and steel, metallurgy, electric power, traffic, petrochemical industry.Because the operating ambient temperature of iron and steel, metallurgy industry and special occasions can reach about 180 ℃, medium-sized electric wire resistance to elevated temperatures is poor, its operational environment is 90 ℃.Can not adapt to abominable high temperature resistant operational environment, the useful life of cable is short, has brought very big hidden danger for the equipment safety operation of cable, influences the normal operation of electrical control equipment, electric power system and the safety of personal property.
At present, the resistance and high temperature resistance property of many cables is poor, can not adapt to bad working environment, has had a strong impact on the useful life of cable.
The utility model content
In order to overcome above-mentioned deficiency, the utility model purpose is to provide that a mass is good, the high-temperature-resisting silicon rubber electrically insulating silicone rubber sheath control cable cable of long service life.
To achieve these goals, the technical scheme below the utility model adopts:
High-temperature-resisting silicon rubber electrically insulating silicone rubber sheath control cable cable; Include the core group that more than one core constitutes; Each core is to be made up of core conductor, insulating barrier from inside to outside successively; Said core group periphery is provided with steel-tape armouring, and the inboard of said steel-tape armouring also is provided with the band inner covering, and its appearance is provided with oversheath; Said insulating barrier and oversheath all are to adopt silastic material to extrude to form.
The thickness of said oversheath should be not less than 1.8mm.
Be provided with filler between said a plurality of core, filler is the non-absorbent material of adhesion core insulating barrier.
Said steel-tape armouring is wrapped on the band inner covering by inside and outside two-layer steel band sinistral coiling shape gap, and wherein, the centre of outer steel band is roughly above internal layer steel band gap, and the band gap should be not more than 50% of width of steel band.
The beneficial effect of the utility model: because insulating barrier, inner sheath and oversheath have adopted silastic material, have, thereby prolonged useful life of cable, widened the range of application of cable than high insulating property and resistant to elevated temperatures characteristic; Owing to adopt the version of steel-tape armouring, not only improved the anti-pressure ability of cable, but also had the function of electromagnetic shielding.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to specify.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, core conductor; 2, insulating barrier; 3, filler; 4, steel-tape armouring; 5, band inner covering; 6, oversheath; 7, core.
