Abstract
The utility model provides a motor lead wire. A conductor of the motor lead wire is sequentially wrapped by a conductor shielding layer, an insulating layer, an insulating shielding layer, a metal shielding layer, an isolating layer, and a sheath layer. The motor lead wire has the characteristics of moisture protection, aging resistance, weather resistance, and the like, and is especially suitable for the stable operation of various high-power high-voltage motors in various complex environments.
Description
Technical field
The utility model belongs to the cable technology field, is specifically related to a kind of motor lead.
Background technology
Along with the high speed development of Chinese Industrialization, the market demand of high-voltage motor also increases substantially, but supporting motor lead still adopts the project organization of traditional cable with it.High-voltage motor is in the moment that starts, and electric current can increase suddenly, causes easily the phenomenons such as corona, partial discharge; So that the conventional motors lead wire is hot easily, insulation and the accelerated ageing of sheath material, the normal service life of reduction cable.
Summary of the invention
The purpose of this utility model provide have excellent protection against the tide, the motor lead of the characteristic such as ageing-resistant, weather.
For achieving the above object, technical solutions of the utility model are as follows.
The utility model provides a kind of motor lead, comprises that its conductor is enclosed with conductor shield, insulating barrier, insulation screen, metal screen layer, separator, restrictive coating outward successively.
Described conductor adopts the multiply tinned copper wire to twist again and forms, and has increased greatly anticorrosive property, flexibility, pull resistance and the field uniformity of cable.
Described insulating barrier adopts ethylene-propylene rubber to extrude, and has higher insulation property and excellent water resistance.
Described conductor shield and insulation screen are extruded by semi-conductive adhesive, can play uniform electric field, improve the high voltage withstanding performance of cable.
Described metal screen layer adopts the tinned copper wire braiding to form, and can play uniform electric field.
Described separator forms by the high temperature resistance polyester band is wrapped, is easy to peeling off of restrictive coating.
Described restrictive coating adopts chlorosulfonated polyethylene to extrude and forms, and has excellent mechanical strength, ozone resistance, resistance to weathering, chemical resistance etc.
The utility model has the advantage of.
1, conductor employing multiply tinned copper wire twists again and forms, and has increased greatly anticorrosive property, flexibility, pull resistance and the field uniformity of cable.
2, insulating barrier adopts ethylene-propylene rubber to extrude, and has higher insulation property and excellent water resistance.
3, conductor shield and insulation screen are extruded by semi-conductive adhesive, can play uniform electric field, improve the high voltage withstanding performance of cable.
4, metal screen layer adopts the tinned copper wire braiding to form, and can play uniform electric field.
5, separator forms by the high temperature resistance polyester band is wrapped, is easy to peeling off of restrictive coating.
6, restrictive coating employing chlorosulfonated polyethylene extrudes and forms, and has excellent mechanical strength, ozone resistance, resistance to weathering, chemical resistance etc.
