Abstract
The utility model discloses a high-temperature-resisting cable. According to the high-temperature-resisting cable, a conductor is made of a plurality of tinned copper wires; a poly(ester-ether) insulating layer is extruded on the conductor made of the tinned copper wires to form an insulated wire core; four insulated wire cores are twisted to form a cable core; high-temperature glass fibers are filled in the cable core to form a filled layer; and a belting layer is lapped, a shielding layer is woven and a sheath layer is extruded and coated on the filled layer sequentially from inside to outside. The high-temperature-resisting cable is high in heat resistance, physical and mechanical properties, electric insulating property and extrusion molding property; and particularly, the properties of the cable can still be kept when continuously used at a high temperature and used in a rapid temperature change environment.
Description
Technical field
The utility model relates to cable industry, is specifically related to a kind of high temperature-resistant cable.
Background technology
Cable is normally by the cable of several or at least two every group stranded similar ropes that form of several groups of wires, mutually insulated between every group of wire, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.
China upgrades to the Urban Transportation such as rolling stock, subway, light rail input substantial contribution at present or transforms, and adopts high-speed overload, to alleviate the crowded situation of communications and transportation and urban pavement
When some industries is used cable, need the operating environment in the face of higher temperature, at this moment with regard to the special requirement cable can be more stable work.
The utility model content
The utility model provides a kind of high temperature-resistant cable, to can at high temperature use continuously with temperature environment jumpy in still retention is stable.
Scheme of the present utility model is as follows: a kind of high temperature-resistant cable, and its conductor adopts the multiply tinned wird, extrudes the polyester ether insulating barrier at described multiply tinned wird conductor and consists of insulated wire cores; Thoroughly do away with edge core twisted synthesizing cable by four and consist of cable core, the filled high-temperature glass fibre forms packed layer in cable core; At packed layer from inside to outside successively wrapped belting layer, woven shield and extrude restrictive coating.
It is material that described belting layer adopts fire-retardant mica tape.
Described screen is soft tinned copper wire woven shield, and places the drainage thread that many tinned copper wires consist of between lapping layer and screen.
Described restrictive coating adopts and is subjected to mineral oil, and the more stable DCH/3-100 chlorosulfonated polyolefin of performance is material after the fuel oil pollution.
The utility model structural design is simple, scientific and reasonable, manufactures easily, and cable insulation adopts polyester ether, Effective Raise the serviceability of product.The utility model also has excellent heat resistance, physical and mechanical properties, electrical insulation capability, extrusion molding, particularly have can at high temperature use continuously with temperature environment jumpy in retention still.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of high temperature-resistant cable, its conductor 1 adopts the multiply tinned wird, extrudes polyester ether insulating barrier 2 at described multiply tinned wird conductor 1 and consists of insulated wire cores; Thoroughly do away with edge core twisted synthesizing cable by four and consist of cable core, the filled high-temperature glass fibre forms packed layer 3 in cable core; At packed layer from inside to outside successively wrapped belting layer 4, woven shield 6 and extrude restrictive coating 7.
It is material that described belting layer 4 adopts fire-retardant mica tape.
Described screen 6 is soft tinned copper wire woven shield, and places the drainage thread 5 that many tinned copper wires consist of between belting layer 4 and screen 6.
Described restrictive coating 7 adopts and is subjected to mineral oil, and the more stable DCH/3-100 chlorosulfonated polyolefin of performance is material after the fuel oil pollution.
The utility model can heat-resisting water or steam, at high temperature the erosion of acid and alkali, alkali, oil; Modulus of elasticity is all better than any thermoplastic resin more than 100 degree; Coefficient of linear expansion is little, and its temperature dependency is also little; Have self-extinguishment, not adding any fire retardant namely has excellent flame retardancy, can reach the UL94V-0 level.Screen in the utility model adopts the tinned copper wire braid shielded and adds drainage thread, makes cable shield effective, if adopt embossing technique then to make whole cable more soft.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
