Utility model content
In order to solve the problems referred to above that prior art exists, the utility model provides a kind of soft, water-fast, weather-proof, chemicals-resistant, the power cable with crosslinked polyethylene insulating layer and thermoplastic elastomer sheath that can adapt to the special occasions uses such as military project, boats and ships, nuclear power, wind energy, railway track traffic, magnetic suspension of high-low temperature resistant, low smoke and zero halogen environmental protection.
The technical scheme that the utility model adopts is:
A kind of power cable with crosslinked polyethylene insulating layer and thermoplastic elastomer sheath, comprise conductor wire core, insulating barrier, flame retardant type filler, fire-retardant band, restrictive coating, the coated described insulating barrier in outside of described conductor wire cable core, coated described fire-retardant band outside described insulating barrier, described flame retardant type filler is filled, the coated described restrictive coating in outside of described fire-retardant band between described insulating barrier and fire-retardant band.
The conductor of described conductor wire cable core adopts high purity oxygen free copper, and described insulating barrier is the insulating barrier that Halogen cross-linking polyethylene materials is made, and described restrictive coating is the restrictive coating that TPE material makes.
The cross-sectional area of described conductor wire cable core is 1-300mm
2.
Described conductor wire cable core comprises some layers, and every layer is the conductor of some stocks with iso-cross-section, and per share conductor is twisted into by some conductor monofilament, and strand between layers adjacent in some layers is on the contrary.
The cross section of described conductive wiring cable core is circular.
Described insulating barrier and described restrictive coating are made by thermoplastic low-smoke halide-free environment-friendly cable material.
Described flame retardant type filler, described fire-retardant band are the fire-retardant band that environment-friendlyflame-retardant flame-retardant material is made, becoming in the gap in the middle of cable core to fill environment-protective glass fibre gasket for packing, then wrapping up one deck high flame retardant alkali-free glass cloth band, isolated insulation layer and outer jacket outside one-tenth cable core.
Every root conductor monofilament of described conductive wiring cable core is circular copper wire.
Described circular copper wire is mainly naked round soft copper single line and overlay coating is the single round copper wire of tin.
Cable inner core in cable outer layer can have that two or more insulated wire cores is stranded to be formed, and also can have three, four, five or more insulated wire cores is stranded to make, and geometry is fixed, and stability is high, on cable can curvature impact very little.The extrusion modling of Halogen crosslinked polyethylene insulation material, by crosslinked special processing, change polyethylene linear molecular structure into solid netted molecular structure, substantially increase the electric property of product, physical property, mechanical performance, ageing resistace and adaptive capacity to environment and other properties, not only high temperature resistant and have the advantages that not prolong combustion and the very strong hydrogen halide of corrosivity can not be produced.Restrictive coating is made up of TPE material, it is a kind of synthetic material having the physical and mechanical properties such as the repetition processability of thermoplastics and the high resiliency of rubber concurrently, there is again excellent reclaiming simultaneously, waterproof, softness, chemical resistance (acid and alkali-resistance, resistance to ozone, resistance to wet goods), heatproof-65 DEG C is a kind of halogen-free environmental material.
The beneficial effects of the utility model are: the utility model does not just discharge pernicious gas and smog when burning, and unlikelyly cause " secondary disaster ", and fail safe is high, environment friendly and pollution-free, can be suitable for various specific occasion lays, and extend product useful life.This product environment for use temperature range :-60 DEG C ~ 125 DEG C, cable long-time running temperature: 90 DEG C ~ 125 DEG C, product appearance is bright and clean smooth, special soft, water-fast, weather-proof, chemicals-resistant, high-low temperature resistant, Low-smoke halogen-free environment-friendlyflame-retardant flame-retardant, meet European Union ROHS standard.Thus reach the designing requirement of scientific and technical innovation, environmental protection, safety non-pollution.This product is widely used in military project, boats and ships, nuclear power, wind energy, railway track traffic, the contour end cable field of magnetic suspension.
