Abstract
The utility model discloses a high-temperature resistant single-core cable which comprises a copper coated aluminum conductor. A conductive insulating layer made of foaming polyethylene material is formed outside the copper coated aluminum conductor through plastic extrusion moulding, A woven shield braided with copper clad aluminum threads is arranged outside the conductive insulating layer, and a polyurethane band winding layer and a ceramic fibre band winding thermal insulation layer are sequentially arranged outside the woven shield. A halogen-free low-smoke flame retardant irradiation crosslinking polyolefin sheath layer is formed outside the ceramic fibre band winding thermal insulation layer through plastic extrusion moulding. The high-temperature resistant single-core cable employs an aluminum conductor and lowers the cost of the cable. The service lifetime of the cable in high-temperature environment is ensured both by the heat insulation structure and a high-temperature resistant polyurethane band winding layer.
Description
technical field:
The utility model relates to cable, relates in particular to a kind of high temperature resistant type single-core cable.
background technology:
Current nonferrous metal price rises suddenly and sharply, and copper conductor cost accounts for the more than 90% of cable raw material total cost.How can ensure to meet the technical indicator of cable copper conductor, can significantly reduce again cable cost, be current problem demanding prompt solution.In addition, the single-core cable on market there will be core damaged phenomenon while mostly work in hot environment, need to change in time, has increased cost.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of high temperature resistant type single-core cable, and selection and reasonable in design, when having reduced cable cost, have also improved resistance to elevated temperatures and the electrical insulation capability of cable.
The technical solution of the utility model is as follows:
High temperature resistant type single-core cable, it is characterized in that: comprise copper clad aluminum conductor, the outer extrusion moulding of described copper clad aluminum conductor has the conduction insulating barrier of polyethylene foamed material, the woven shield that conduction insulating barrier adopts the braiding of copper cover aluminum silk thread to form outward, woven shield is provided with polyurethane tape lapping layer, the wrapped thermal insulation layer of ceramic fibre strip outward successively, and the outer extrusion moulding of the wrapped thermal insulation layer of ceramic fibre strip has LSOH anti-flaming cross-linking radiation polyolefin jacket layer.
Described high temperature resistant type single-core cable, is characterized in that: the count of described woven shield is not less than 75%.
Described high temperature resistant type single-core cable, is characterized in that: the wrapped coverage rate of the described wrapped thermal insulation layer of ceramic fibre strip reaches 100%.
The utility model has the advantages that:
The utility model adopts copper clad aluminum conductor, has reduced the cost of cable, by heat insulation structural and resistant to elevated temperatures polyurethane tape lapping layer is two-way has improved the useful life of cable in hot environment.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to accompanying drawing:
High temperature resistant type single-core cable, comprise copper clad aluminum conductor 1, the outer extrusion moulding of copper clad aluminum conductor 1 has the conduction insulating barrier 2 of polyethylene foamed material, the woven shield 3 that the braiding of the outer employing copper cover aluminum of conduction insulating barrier 2 silk thread forms, woven shield 3 is outer is provided with polyurethane tape lapping layer 4, the wrapped thermal insulation layer 5 of ceramic fibre strip successively, and the outer extrusion moulding of the wrapped thermal insulation layer 5 of ceramic fibre strip has LSOH anti-flaming cross-linking radiation polyolefin jacket layer 6.
The count of woven shield 3 is not less than 75%.
The wrapped coverage rate of the wrapped thermal insulation layer 5 of ceramic fibre strip reaches 100%.
