Abstract
The utility model discloses a silicon rubber insulated tensile low-temperature-resistant mobile control cable. The silicon rubber insulated tensile low-temperature-resistant mobile control cable is characterized in that a silicon rubber insulating layer (2) wraps a conductor (1) in an extruding manner to form an insulating wire core; a plurality of wire cores are twisted with a glass fiber rope of a filling layer (3) to form a cable core; and a silicon rubber inner sheath (4), a nylon-woven mesh reinforced layer (5) and a nitrile polyvinyl chloride compound outer sheath (6) sequentially wrap outside the cable core. The cable has excellent heat resistance, cold resistance, dielectric property, ozone resistance, resistance to atmospheric aging and the like, can be used for a long period of time at -60 DEG C (or lower temperature); and a reinforced protective layer, namely the butyronitrile outer sheath is arranged outside the silicon rubber inner sheath, so that the tensile strength of the cable is greatly improved; and the mechanical properties of poor tensile strength, tearing strength and the like of the silicon rubber are effectively compensated.
Description
Technical field
The utility model relates to the low temperature resistant moving control cable of a kind of silicon rubber insulation tension, particularly at occasion silicon rubber insulated movable control cables such as low temperature, frequent movements; Belong to technical field of electric wires and cables.
Background technology
Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety satisfies rate and domestic market occupation rate all over 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes in the world first electric wire producing country.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.
China's economic growth continuously and healthily, for cable products provides the huge market space, the temptation that Chinese market is strong makes the world all focus on Chinese market to sight, reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry allows the world regard with special esteem.Along with the continuous expansion of the industry sizes such as China Power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire industry also has huge development potentiality.
In numerous synthetic rubber, silicon rubber is outstanding person therein.It has tasteless nontoxic, is not afraid of high temperature and resists the characteristics of severe cold, and " keeping cool ", " remaining calm " when 300 degrees centigrade and subzero 90 degrees centigrade are not still lost original intensity and elasticity.Silicon rubber also has good electrical insulating property, oxytolerant ageing resistance, fast light ageing resistance and mildew resistance, chemical stability etc.Owing to having had these excellent performances, make silicon rubber can be applicable in cables manufacturing.The ordinary silicon rubber cable has the excellent performances such as thermal endurance, cold resistance, dielectricity, anti-ozone and anti-atmospheric aging, and the outstanding performance of silicon rubber is that serviceability temperature is broad, can be-60 ℃ (or lower temperature) lower long-term the use.But the mechanical performances such as its tensile strength of common silicone rubber for cable and tearing toughness are relatively poor, and its physical and mechanical properties is also not as good as most of synthetic rubber cables at normal temperatures.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of silicon rubber insulation tension low temperature resistant moving control cable.
The purpose of this utility model is achieved through the following technical solutions:
The low temperature resistant moving control cable of silicon rubber insulation tension, its design feature is, extrude silicone rubber insulation layer outward by conductor and consist of insulated wire cores, stranded formation cable core together with the glass cord of many cores and packed layer, described cable core is coated with the silicon rubber inner sheath outward successively, the meshed strengthening layer of knit nylon and butyronitrile polyvinyl chloride composite oversheath.
The utility model design feature also is:
Described conductor adopts the soft copper lay configuration.
The count of described meshed strengthening layer is greater than 90%.
Advantage of the present utility model is mainly reflected in:
1, the utility model insulating barrier and sheath adopt silicon rubber, cable has the excellent performances such as thermal endurance, cold resistance, dielectricity, anti-ozone and anti-atmospheric aging, can be-60 ℃ (or lower temperature) to+250 ℃ (or higher temperature) lower long-term the use.
2, the utility model is provided with heavy seal coat butyronitrile oversheath in silicon rubber rubber inner sheath outside, improved greatly cable tensile strength, has effectively made up the mechanical performances such as the relatively poor tensile strength of silicon rubber and tearing toughness.
3, be provided with the knit nylon reinforced layer between the utility model inner sheath and oversheath, so just greatly increased the whole tensile property of cable, adopt simultaneously the knit nylon reinforced layer can not reduce the bending property of cable.
4, the utility model does not need to change cable material, just changes the construction of cable and production technology, guarantees that cable has the characteristics such as low temperature resistant, tension.The cable long service life, and cost is low, has good Social benefit and economic benefit.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure: 1 conductor, 2 silicone rubber insulation layers, 3 packed layers, 4 silicon rubber inner sheaths, 5 knit nylon reinforced layers, 6 butyronitrile polyvinyl chloride composite oversheaths.
Below by embodiment, technical solutions of the utility model are described further.
Embodiment
As shown in Figure 1, cable is comprised of conductor 1, silicone rubber insulation layer 2, packed layer 3, silicon rubber inner sheath 4, knit nylon reinforced layer 5 and butyronitrile vinyl chloride compound oversheath 6.
In concrete enforcement, conductor 1 adopts the soft copper bundle structure that tangles, and its outer silicone rubber insulation layer 2 that extrudes consists of insulated wire cores, extrudes the employing continuous vulcanization; The glass cord that many eradication edge cores and packed layer 3 adopt is stranded formation cable core together, the cable core outside extrudes high-strength tear-resistant and splits silicon rubber inner sheath 4, adopt the netted reinforced layer 5 of knit nylon, the count of meshed strengthening layer is greater than 90%, and the outer employing butyronitrile of reinforced layer 5 polyvinyl chloride composite oversheath 6 extrudes moulding.
