solar photovoltaic power generation technology will be one of green energy technology in the future. Solar, or photovoltaic (pv) application is more and more widely in China. In addition to government support the rapid development of photovoltaic power plants, private investors are also actively build factories, and plans to put them into to the production of solar modules, solar modules worldwide sales. In order to build a cost-effective and profits of the photovoltaic power station, solar cable manufacturer represents all of the important goals of the solar manufacturers and core competitiveness. In fact, profitability depends not only on the efficiency of solar battery components themselves or the high performance, also depends on a series of component seems to have no direct relation with the components. However, without the use of solar energy special cable will affect the service life of the whole system. In fact, the solar system is usually used in harsh environment conditions, such as high temperature and ultraviolet (uv) radiation. In Europe, sunny day will result in the solar system in the field temperature as high as 100 ℃. At present, we can use PVC, rubber, thermoplastic elastomer crosslinking and high quality material, but, unfortunately, rubber cable rated temperature is 90 ℃, and even rated temperature is 70 ℃ polyvinyl chloride (PVC) cable is often used in outdoor. Obviously, this will greatly affect the service life of the system. Stress caused by outside influence for photovoltaic applications, outdoor materials should be based on ultraviolet radiation, ozone, severe temperature changes and chemical attack. Under pressure from the environment using low grade material can lead to cable sheath is fragile, and even the decomposed cable insulation. All of these conditions can directly increase the wastage of the cable system, and the risk of cable short circuit will increase. From the medium and long term, the possibility of a fire or personal injury will be higher. Solar cable is a kind of rated temperature is 120 ℃ electron beam crosslinking cable, able to withstand extreme weather conditions and equipment of mechanical shock. According to international standard IEC216, RADOX solar cable, its service life in outdoor environment is 8 times that of the rubber cable, PVC cable is 32 times. These cables and components not only has excellent weather resistance, resistance to ultraviolet ray and ozone erosion resistance, can also withstand a wider range of temperature change, For example - 40 ℃ to 125 ℃) 。 In order to deal with potential dangers from the high temperature, manufacturers prefer to use double insulation rubber sheathed cables. However, this type of cable standard version allows only use under 60 ℃ high temperature. In Europe, on the roof measuring temperature of 100 ℃ solar cable rated temperature of 120 ℃ ( Can be used 20000 hours) 。 The rating equal to under the steady temperature of 90 ℃ using 18 years; However, when the temperature is below 90 ℃, its service life is longer. Generally requires the use of solar energy equipment, with up to 20 - life More than 30 years.
