Structure of the vacuum load switch in many forms, and as China's urban and rural power grids and structural innovation; the existing main indoor and outdoor vacuum load switch vacuum load switch into two categories, outdoor vacuum load switch is in the country rural power grid construction and transformation developed for use in the address field of the environment in rural areas, with a unique style of architecture. Vacuum load switch is characterized by light weight, small size, without a strong sound and light phenomenon Suzhou high voltage switches in breaking the current process, the vacuum interrupter contacts with a copper tungsten or copper alloy iron selenium and tellurium, greatly reducing the closure value and strengthen the ability of anti-welding Zhenjiang high voltage load switch, its mechanical life and electrical life greatly exceeds the average load switch, can reach more than 2,000 times the number of operations. Vacuum load switch load switch comparison with other types of high-voltage load switch, the most prominent is the breaking of good performance, to meet the requirements of the transfer of current and long service life. And sulfur hexafluoride load switch compares roughly equal in this respect. They all belong to the maintenance and repair and low maintenance type of switch. As compared with compressed air or gas-type load switch, only the price is lower than the vacuum load switch with minor - some, while others do not compare the performance and parameters and vacuum load switch. Because of this, the early sixties of the last century in the power system and the emergence of sulfur hexafluoride vacuum interrupter media as two new switches. And during the seventies - eighties, most experts believe that sulfur hexafluoride switch has an absolute advantage for 110 kV -500 kV voltage level or even higher in the direction of development, but only applied to medium vacuum switch Wuxi high-voltage load switch voltage areas, according to the development trend in recent years that the vacuum switch may not only to the development of high-voltage, low voltage level at the same time to develop. Zhenjiang high voltage load switch, high voltage switches, power is supplied by the Xi'an Huayi Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Huayi power and you hand into the brilliant, for a better future!
