Abstract
The utility model discloses an electric power cable for a solar energy photovoltaic generating device, comprising a cable core, an insulation layer and an outer sheath which are set front interior to exterior, wherein the insulation layer and the outer sheath use low-fume no-halogen thermosetting polymer material and are respectively and successively subjected to irradiation crosslinking treatment. The high temperature resistance of the electric power cable can be 120 centigrade and the electric power cable can resist the heavy weather circumference and mechanical shock and can greatly increase the safety performance and service life of the solar energy photovoltaic generating device.
Description
Technical field
The utility model relates to the cable technology field, exactly relates to a kind of power cable for solar photovoltaic power generation assembly that is applicable to.
Background technology
Day by day extensive along with photovoltaic generation, thereby driven development with the solar power generation Related product, solar power system usually is to use under severe environmental conditions, as high temperature and radiation, and the common employing of people now is polyvinyl chloride insulation and polyvinyl chloride oversheath, adopt common cable long-term solar light irradiation of process in atmosphere of this material, wind and rain and ozone corrode the back cable surface crack performance will occur, the physical and mechanical properties of product reduces greatly, so the common wiring cable has more potential hazard in the process of using, not weather proof, UV resistant and ozone corrode, and cause the building block of photovoltaic generation special equipment to damage the useful life that also directly has influence on whole system.Based on all factors, in solar energy power generating equipment, use and just to seem particularly urgent by special solar cable weather proof, that UV resistant shines and ozone corrodes.
The utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of weatherability, the power cable for solar photovoltaic power generation assembly that UV resistant irradiation and anti-ozone corrode, adopt the utility model, its high temperature resistant degree can reach 120 ℃, can resist extreme climate environment and stand mechanical shock, can significantly improve solar energy power generating device ' and useful life.
The utility model is achieved by the following technical solution:
A kind of power cable for solar photovoltaic power generation assembly, comprise cable core from inside to outside successively, insulating barrier and oversheath, described insulating barrier and oversheath all adopt the low smoke and zero halogen thermoset copolymer material, and insulating barrier and oversheath are taken up in order of priority and are carried out cross-linking radiation and handle.
Described low smoke and zero halogen thermosetting polymer is a low-smoke non-halogen flame-retardant cross-linking radiation polyolefin.
Described priority is carried out cross-linking radiation and is handled and to be meant that insulating barrier carries out after cross-linking radiation handles, and extrudes the oversheath of low smoke and zero halogen thermoset copolymer material again on insulating barrier, again oversheath is carried out cross-linking radiation and handles.
Described cross-linking radiation is evenly finished cross-linking process by the irradiation scanning window of high-energy electron accelerator after handling the insulating barrier or oversheath cooling that is meant after extruding.
Described cable core comprises conductor and the separator that surrounds on the conductor.
Described separator is a non-hygroscopic band matter.
Advantage of the present utility model is:
Because insulating barrier of the present utility model and oversheath all adopt the low smoke and zero halogen thermoset copolymer material, compare with the polyvinyl chloride oversheath with existing polyvinyl chloride insulation, have weatherability preferably, advantages such as UV resistant irradiation and anti-ozone erosion; And insulating barrier and oversheath carry out cross-linking radiation respectively to be handled, owing to do not add crosslinking agent during cross-linking radiation, be effectively to penetrate insulating barrier and oversheath when crosslinked by the high-power electron beam that high-energy electron accelerator produces, produce cross-linking reaction by power conversion, because electronics has very high energy, and pass insulating barrier and oversheath equably, so the cross-bond that forms is in conjunction with the energy height, good stability, the physical property that shows is: the insulating barrier behind the cross-linking radiation and the mechanical strength of jacket material increase, the creep-resistant property of cold flow improves, modulus of elasticity increases, and the most important thing is the thermal endurance of insulating barrier and oversheath, the variation of solvent resistance and resistance to cracking and raising.So high temperature resistant degree of the present utility model can reach 120 ℃, can resist extreme climate environment and stand mechanical shock, can significantly improve solar energy power generating device ' and useful life.
