Abstract
The utility model discloses an environmental-friendly polyolefin insulated radiation cross-linked high-temperature-resistant composite wire and cable, which is composed of a conductor, a cross-linked polyolefin insulation layer and a surface layer; the cross-linked polyolefin insulation layer is coated on the conductor; the surface layer is coated on the cross-linked polyolefin insulation layer; the cross-linked polyolefin insulation layer is 0.2 to 2.0 mm in thickness. The utility model can achieve the non-halogen and low-smoke environment-friendly effects, with the flame-retardant level reaching VW-1 and FT2; the cable contains no harmful heavy metals and has superior performance and proper price; a composite structure of a nylon jacket can be extruded on the cross-linked polyolefin surface coating, so that the cable has abrasion resistance, oil resistance and anti-adhesion properties under high temperature and other excellent performances and can be widely used in various fields.
Description
Technical field
The utility model relates to a kind of electric wire.
Background technology
Development along with electrical applications, at automobile, boats and ships, Aeronautics and Astronautics, military, medicine equipment with the electric equipment and the higher field of security performance of harsh climate environment are arranged, requirement to electric wire is also very high, that requirement has is high temperature resistant, heat shock resistance, anti-ozone, chemically-resistant solvent and good electrical insulation properties, also require wear-resistant, oil resistance.And existing common wiring can not reach this requirement.
The utility model content
Technological deficiency at the prior art existence, the purpose of this utility model is to have overcome above-mentioned shortcoming, provide a kind of ageing-resistant performance strong, wear-resistant, oil resistance is strong, and the high temperature resistant compound electric wire of environment-friendly polyolefin insulation cross-linking radiation of anti-ozone, chemically-resistant solvent and good electrical insulation properties.
The technical scheme in the invention for solving the technical problem is: the high temperature resistant compound electric wire of a kind of environment-friendly polyolefin insulation cross-linking radiation, it is made up of conductor, cross-linked polyolefin insulating barrier and top layer, described cross-linked polyolefin insulating barrier is coated on outside the conductor, described top layer is coated on outside the described cross-linked polyolefin insulating barrier, and the thickness of described cross-linked polyolefin insulating barrier is 0.2～2.0mm.
The high temperature resistant compound electric wire of described environment-friendly polyolefin insulation cross-linking radiation, the thickness on described top layer is 0.01～0.20mm.
The high temperature resistant compound electric wire of described environment-friendly polyolefin insulation cross-linking radiation, described top layer is dope layer or nylon sheath wire.
The high temperature resistant compound electric wire of described environment-friendly polyolefin insulation cross-linking radiation, described conductor is naked copper, nickel-clad copper or nickel-clad copper conductor.
The high temperature resistant compound electric wire of this environment-friendly polyolefin insulation cross-linking radiation of the present utility model, adopt conductor, cross-linked polyolefin insulating barrier and top layer three-decker to form, owing to have high temperature resistant, heat shock resistance, anti-ozone, chemically-resistant solvent and good electrical insulation properties, the advantages such as useful life that prolonged electric wire by the polyolefin insulation electric wire behind the irradiation.Polyolefin by improvement can reach not halogen-containing, the environment protecting of low cigarette, fire-retardant rank reaches VW-1 and FT2, do not contain harmful heavy metal, superior performance, price is suitable, is the optimal selection that substitutes the electric wire of PVC insulation material, at the cross-linked polyolefin face coat or extrude the composite structured excellent performance that makes electric wire resist high wearing and tearing, grease resistance, the anti-stick company of high temperature of nylon sheath wire, can be widely used in a plurality of fields.
