The high-cold-resistant torsion-resistant power cable is reasonable and simple in structure, is easy to produce and manufacture, is low in cost, has high operational performance, superior electrical property, physical and mechanical properties, chemical stability property, high-low temperature resistance, tear resistance, ultraviolet (ozone-resistance) resistance and abrasion resistance, can carry high mechanical external force friction, and has long service life. The cable is an ideal cable applied to an instrument in an automatic control system of solar power plants, solar buildings, solar outdoor lighting and the like.
Description
Technical field
The present invention relates to a kind of cable, particularly relate to a kind of resistance to high and cold anti-twist power cable.
Background technology
The resistance to high and cold anti-twist Low ESR power transmission cable of photovoltaic generation Salt And Alkali Tolerance is by comprising screen and sheath that the insulated wire cores of extruded insulation layer on conductor and cable core by insulated wire cores stranding are arranged, it is characterized in that described insulating barrier is for be made up of inside and outside insulating barrier, is provided with uvioresistant layer between described screen and sheath.Have reliable useful life, thermal stability, moisture resistance, excellent electric property, physical and mechanical properties, high flame resistance, resistance to elevated temperatures, shock resistance resist bending, sheath do not ftracture, long service life.This cable is solar power plant, solar building, solar energy outdoor lighting etc. automation control system in instrument ideal select cable.
The resistance to high and cold anti-twist Low ESR power transmission cable of photovoltaic generation Salt And Alkali Tolerance is mainly used in solar power plant, solar building, the automation control system of solar energy outdoor lighting etc., in these occasions because of environment and need of work, major part instrument cable can make cable occur the aging or not wear-resisting phenomenon of sheath of ultraviolet light (ozone) under the mal-condition of the sunlight of high strength or under External Force Acting, cable is needed to have superpower UV resistant (resistance to ozone) or anti-wear performance, adopted improvement sheath material formula to improve UV resistant (resistance to ozone) performance of sheath material or mechanical performance can only solve subproblem in the past, ultraviolet (ozone) aging phenomenon under solar glare irradiation or the not wear-resisting phenomenon of sheath under External Force Acting fail fundamentally to solve, as long as problems occurs to cause the wasting of resources, and cause difficulty to construction.
Summary of the invention
Object of the present invention is exactly the deficiency existed for above-mentioned existing cable, there is provided a kind of and there is excellent electric property, physical and mechanical properties, chemical stability, high and low temperature resistance, uvioresistant (resistance to ozone) performance and anti-wear performance, the resistance to high and cold anti-twist power cable of larger mechanical external force rubbing action can be born.
Technical scheme of the present invention is: this cable comprises screen and sheath that the insulated wire cores of extruded insulation layer on conductor and cable core by insulated wire cores stranding are arranged, described insulating barrier is made up of inside and outside insulating barrier, described inner insulating layer is arranged on conductor, described external insulation layer is arranged between screen and uvioresistant layer, is provided with uvioresistant layer between described screen and sheath.
The thickness proportion of described inside and outside insulating barrier is 3:7.
Described screen is the proof copper-wire braided layer that density reaches 95%.
The uvioresistant fiber band lapping layer that described uvioresistant layer requires for meeting Aero-Space.
The material of described sheath is the special, wear-resistant nylon silastic material meeting GB/T5013-2008 requirement.
The present invention is simply rational in infrastructure, and manufacture easily, cost is low, and serviceability is good.There is excellent electric property, physical and mechanical properties, chemical stability, high and low temperature resistance, tear resistance, uvioresistant (resistance to ozone) performance and anti-wear performance, larger mechanical external force friction can be born, long service life.This cable is instrument ideal chose cable in the automation control system of solar power plant, solar building, solar energy outdoor lighting etc.
