Abstract
The utility model discloses a cable with a high temperature resistant and silastic insulating layer and a silastic protective jacket. The cable comprises a soft copper conductor, a silastic insulating layer and a silastic protective jacket, wherein, the soft copper conductor is made by the stranding of the conductor; the soft copper conductor is coated with the silastic insulating layer to form an insulating core and the insulating core is coated by the silastic protective jacket. The cable can be made into the cable with single or more cores and applicable for the transmission of 10kv or less power; the working temperature thereof ranges from -60 DEG C to 260 DEG C and the cable has better heat resistance performance, coldness resistance performance and flexibility and can work normally and stably at the rated high temperature without influence on the signal or power transmission performance and being capable of keeping longer service life, thereby being applicable to high and low temperature resistance situations in aeronautics and astronautics, metallurgy, petroleum, chemical industry and other industries.
Description
Technical field
The utility model relates to the cable that is used for electric power, communication and associated transport purposes, exactly is insulation of heat-resisting, high-temperature-resisting silicon rubber and jacketed cable.
Background technology
Existing ordinary silicon rubber-covered and jacketed cable, its operating temperature range is-60 ℃～180 ℃, greater than 180 ℃ of hot environment work the time, easily produce ageing of insulation, incipient scorch phenomenon, make cable lose performance, be damaged and can not use, cause cable useful life short, change problems such as frequent, operation and maintenance cost height.
The utility model content
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of high-temperature-resisting silicon rubber insulation and jacketed cable.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of high-temperature-resisting silicon rubber insulation and jacketed cable comprise soft copper conductor, silicone rubber insulation layer and silicone rubber jacket, and described soft copper conductor is formed by the conductor bundle strand, and the soft copper conductor extrudes silicone rubber insulation layer outward and forms insulated wire cores, and skin extrudes silicone rubber jacket.
Described cable is a single-core cable, and its insulated wire cores directly extrudes silicone rubber jacket outward.
Described cable is a multicore cable, thoroughly does away with the edge core and high temperature resistant filler twists together more, and after rolling with high temperature resistant band bag, is formed into cable core, becomes cable core to extrude silicone rubber jacket outward.
Described soft copper conductor is formed by the 5th kind or the 6th kind of conductor bundle strand.
The utility model can be made into single core and above, 10kV and following electric wire, operating temperature range is at-60 ℃～260 ℃, have better heat-resisting, low temperature resistant and bending property, under high temperature rated, can normally stably work, signal or electric energy transmitting performance are unaffected, can also guarantee that cable has long useful life, is applicable to the high-low temperature resistant occasion of industries such as Aeronautics and Astronautics, metallurgy, oil, chemical industry.
Description of drawings
Fig. 1 is the cross-section of cable schematic diagram of the utility model first embodiment;
Fig. 2 is the cross-section of cable schematic diagram of the utility model second embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of reference numerals is as follows:
1. soft copper conductor
2. silicone rubber insulation layer
3. high temperature resistant filler
4. high temperature resistant band
5. silicone rubber jacket
As shown in Figure 1, this cable is a single-core cable, is made up of soft copper conductor 1, silicone rubber insulation layer 2 and silicone rubber jacket 5, and soft copper conductor 1 is formed by the 5th kind or the 6th kind of conductor bundle strand, the soft copper conductor extrudes silicone rubber insulation layer 2 outward and forms insulated wire cores, and insulated wire cores directly extrudes silicone rubber jacket 5 outward.Regulation among the GB/T3956-1997 " conductor of cable ", conductor is divided into four kinds: the 1st kind, the 2nd kind, the 5th kind and the 6th kind.The 1st kind and the 2nd kind is intended for the fixedly conductor of cabling, and the 1st kind is solid conductor, and the 2nd kind is stranded conductor, the 5th kind and the 6th kind of conductor that is intended for flexible cable and flexible cord, and the 6th kind of the 5th kind of ratio is more soft.
As shown in Figure 2, this cable is a multicore cable, form by soft copper conductor 1, silicone rubber insulation layer 2 and silicone rubber jacket 5, soft copper conductor 1 is formed by the 5th kind or the 6th kind of conductor bundle strand, the soft copper conductor extrudes silicone rubber insulation layer 2 outward and forms insulated wire cores, and three thoroughly do away with the edge cores and high temperature resistant filler 3 twists together, and with high temperature resistant band 4 wrap roll after, be formed into cable core, become cable core to extrude silicone rubber jacket 5 outward.
This cable has excellent high and low temperature resistance, it is base material that its insulation and sheath adopt methyl vinyl silicone rubber, process by modification and cooperation, thereby make its temperature resistant grade improve 80 ℃, because of methyl vinyl silicone rubber is the silicon rubber versatile material, low price, thus make this cable when heat resistance, mechanical performance improve greatly, have minimum manufacturing cost.In addition, by the application of flame-retarded technology, this cable also can expand to flame retardant products, by the cooperation of special reinforcing agent, can make the mechanical and physical performance of this cable insulation and sheath improve about 20%.Have working temperature height (260 ℃), resistance to low temperature good (60 ℃), long service life, current capacity is strong, electrical property is excellent, anti-ozone aging, oxygen aging, light aging, atmospheric aging, cost are low, environmental protection, safety, soft pliable song, the characteristics such as convenient of laying are installed.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.Though but on its shape or structure, do any variation, every identical with the utility model or akin technical scheme is all within its protection range.
