Load switch uses? Load switch is a switch between electrical circuit breakers and disconnectors between the interrupter device has a simple load switch price, can cut off the rated load current and a certain overload current, but can not cut off the short-circuit current. In simple terms, it is that you can cut with a load current switching equipment. Vacuum load switch and load switch to other types of contrast, the most prominent is breaking performance, to meet the current requirements divert and long service life. And sulfur hexafluoride load switch relatively roughly equal in this respect. They all belong to the maintenance and repair and low maintenance type of switch. As with the puffer type gas load switch or compare load switch, only the price is lower than the vacuum load switch minor - some, while others do not compare performance and parameters and vacuum load switch. Because of this, the early sixties of the last century in the power system emerged as sulfur hexafluoride and vacuum arc medium two new switches. And during the seventies - eighties, most experts believe that sulfur hexafluoride switch has an absolute advantage for 110 kV -500 kV Xi'an load switch, voltage levels even higher direction of development, while the vacuum switch is just used in the field of medium voltage load switch factory outlets, according to the development trend in recent years that the vacuum switch is not only possible to develop a high voltage level, while the low voltage level development. High voltage switches, Huayi Electric Power (certified), Lhasa load switch provided by Xian Huayi power plant. Xian Huayi Electric Power Equipment Factory (www.xahy.com) is a leader in Xi'an high-voltage circuit breakers, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Huayi Electric Power leadership with the staff warmly welcome all inquiries negotiations to create Huayi electricity better future.
