Technical field
The utility model relates to a kind of photovoltaic cable, especially a kind of solar energy equipment photovoltaic cable.
Background technology
Along with the raising of human environmental consciousness, huge transformation is occuring in the world energy sources structure, is the sustainable new energy resources system transformation on basis to regenerative resource by the fossil energy system namely.Solar energy becomes the topmost energy resources in the whole world, thereby solar power generation should be the main force that extensive electric power will be provided future, is the main direction of extensive development.In recent years, world's photovoltaic cell industry is developed rapidly, the sun energy generating capacity 20MW that China has developed, and photovoltaic generation is in the world one of fastest-rising industry.
Solar cell is the device that directly light energy conversion is become electric energy by photoelectric effect or Photochemical effects.Take the thin-film type solar cell of photoelectric effect work as main flow, then also be in the budding stage with the wet type solar cell of Photochemical effects work.All solar cells all produce direct current and need the conversion alternating current.Photoelectric source with certain capacity needs many thousand unit modules to form, and couples together each unit module is well-regulated, well imagines to comprise a lot of insulation fine rules in the construction of cable.The initial research photovoltaic cell, main energy is to element and combined aspects thereof, has also mentioned schedule for the research of cable at present.Over past ten years, the rapid growth of global optical energy power market, and photovoltaic cable does not still have international standard, therefore referential standard and test need be adjusted.The structure of photovoltaic cable seems simply, but its operational environment, the moment is exposed under the sunlight, usually can use under severe environmental conditions, such as high temperature and ultraviolet radiation.In Europe, to cause the scene temperature of solar energy system up to 100 ℃ when fine, add that combustible is numerous in the operational environment, one these combustibles are unable to bear scorching of high temperature, dieseling will occur, cause burning, will cause a photovoltaic system to damage, have influence on the useful life of whole system, perhaps cause short circuit, fire and personnel to injure the appearance of the problem such as dangerous.So, designs and a kind ofly have good weather resistance, UV resistant, anti-ozone aggressivity and excellent endurable ability, and the solar energy equipment that can bear variations in temperature in larger scope has urgent meaning with photovoltaic cable.
Summary of the invention
The utility model provides a kind of solar energy equipment photovoltaic cable, it has solved existing photovoltaic cable and has been used for the endurable ability that the solar energy equipment photovoltaic cable does not have good weather resistance, UV resistant, anti-ozone aggressivity and excellence, and can bear the problems such as variations in temperature in larger scope.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of solar energy equipment photovoltaic cable comprises conductor, and described conductor is followed successively by insulating barrier and restrictive coating from the inside to surface, and described conductor is included as through the stranded copper wire that forms of stranding machine, and its twisting pitch is not more than 10 times of copper wire external diameter.
Further, a kind of preferred version of the present utility model: described insulating barrier adopts low-smoke halide-free fireproof composite polyolefine material.
Further, a kind of preferred version of the present utility model: described insulating barrier average thickness is not less than 0.5mm.
Further, a kind of preferred version of the present utility model: described restrictive coating adopts low-smoke halide-free fireproof composite polyolefine material.
Further, a kind of preferred version of the present utility model: described sheath average thickness is not less than 0.8mm.
The beneficial effects of the utility model:
Solar energy equipment of the present utility model adopts the copper bar that meets the GB/T3952 standard code to pull into copper wire by company's wire drawing machine with the conductor of photovoltaic cable, copper wire size and electrical property will meet the regulation of GB/T3953 standard, and through the stranded conductor that forms of stranding machine, its electrical property meets the GB/T3956 standard code.Its twisting pitch is not more than 10 times of external diameter.
Insulating barrier adopts low-smoke halide-free fireproof composite polyolefine material, by insulating exruded unit Insulation Material is extruded on the conductor, and carry out cross-linking radiation through irradiation apparatus, the insulation average thickness is not less than 0.5mm, restrictive coating adopts low-smoke halide-free fireproof composite polyolefine material, by company's sheathing unit protective cover material is extruded in the insulation, and carries out cross-linking radiation through irradiation apparatus.The sheath average thickness is not less than 0.8mm, the huge variations in temperature that photovoltaic cable can be born.
