Abstract
The invention provides a capacity-increasing and energy-saving flexible cable used in a power station. A conductor screen layer, an insulative layer, an insulative screen layer, a copper strip armor layer, an outer insulative layer, a flame retardant layer and a protective sleeving layer are wrapped outside a conductor in sequence. The capacity-increasing and energy-saving flexible cable used in the power station has the advantages of being energy-saving, pulling resistant, flame resistant, weather resistant, good in bending radius and the like, thereby being especially suitable to be used as a main line cable of a power station unit.
Description
Technical field
The present invention relates to a kind of cable, be specifically related to a kind of power station volume increasing and energy saving flexible cable.
Technical background
The power station unit generally adopts three-core structure with flexible cable, and laying installation is disposable to be completed, but between cable weak heat-dissipating, cable core, thermal resistance is large, and cable conductor resistance in conduct electrical power becomes large, and electric energy loss rolls up; 400 square millimeters, cross section and above cable, percent defective is quite high in production link, and most cable factories do not possess the production capacity in this cross section at home.If select conventional single cored structure, its good heat dissipation relatively improved 30% with its conductor ampacity of cross section three-core structure, but the cable laying workload is large, easily causes threephase load unbalanced.In conjunction with the pluses and minuses of three-core cable and single-core cable, a kind of production technology is simple, construction install convenience, heat radiation is excellent, bending radius is large cable not only can be saved the consumption of noble metal, can also reduce every waste in the cable production process.
Summary of the invention
The purpose of this invention is to provide have excellent heat radiation, environmental protection, energy-conservation, bending radius large, lay easy power station volume increasing and energy saving flexible cable.
For achieving the above object, technical solution of the present invention is as follows:
The invention provides a kind of power station volume increasing and energy saving flexible cable, comprise that its conductor is enclosed with conductor shield, insulating barrier, insulation screen, copper strips armour, external insulation layer, flame retardant coating and 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 semiconductive, can play uniform electric field, improve the high voltage withstanding performance of cable.
Described copper strips armour employing S type is two buckles sheathed structure, makes cable have excellent bearing capacity, also can bear stronger oblique pulling, and construction and installation are very convenient; Form the helical duct of hollow between copper strips armour and insulation screen, be conducive to the heat radiation of single-core cable, reduce electric energy loss, also can play uniform electric field, be used for ground protection, can avoid casualties in irresistible accident.
Described external insulation layer adopts the stacked package of polyimides band to form, it is one of high-molecular organic material of combination property the best in all kinds of insulating material, high temperature resistant reaching more than 400 ℃, long-term serviceability temperature scope-200～300 ℃, without sharp melting point, high insulating property, 103 hertz of lower dielectric constants 4.0, dielectric loss only 0.004～0.007 belongs to F to H class F insulating material F.
Described flame retardant coating adopts double-deck synthetic mica tape wrapped, and its tensile strength is good, and fire line is high.
Described restrictive coating adopts chlorosulfonated polyethylene, its excellent ozone resistance, resistance to weathering, chemical resistance etc., physical and mechanical properties, ageing-resistant performance, heat-resisting and lower temperature resistance, oil resistance, flame resistance, resistance to wear, and anti-electrical insulating property preferably.
The invention has the advantages that:
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, master core conductor shield and master core insulation screen are extruded by semiconductive, can play uniform electric field, improve the high voltage withstanding performance of cable.
4, copper strips armour employing S type is two buckles sheathed structure, makes cable have excellent bearing capacity, also can bear stronger oblique pulling, and construction and installation are very convenient; Form the helical duct of hollow between copper strips armour and insulation screen, be conducive to the heat radiation of single-core cable, reduce electric energy loss, also can play uniform electric field, be used for ground protection, can avoid casualties in irresistible accident.
5, it is wrapped that flame retardant coating adopts double-deck synthetic mica tape, and its tensile strength is good, and fire line is high.
6, external insulation layer adopts the stacked package of polyimides band to form, it is one of high-molecular organic material of combination property the best in all kinds of insulating material, high temperature resistant reaching more than 400 ℃, long-term serviceability temperature scope-200～300 ℃, without sharp melting point, high insulating property, 103 hertz of lower dielectric constants 4.0, dielectric loss only 0.004～0.007 belongs to F to H class F insulating material F.
