High voltage vacuum circuit breaker "because after extinguishing medium and arcing contacts dielectric gap is named after the high vacuum, which has a small size, light weight, suitable for frequent operation, no maintenance advantages interrupter in with grid application is more popular. Xi'an Huayi power plant is the high-voltage electrical equipment backbone enterprises, leading products 6-110kV high-voltage vacuum circuit breakers, low voltage switch cabinet, box-type substation, power transformers, voltage and current transformers, high-voltage fuse, load switch, disconnecting switch, zinc oxide surge arresters, harmonic elimination, wall bushing, post insulators, high voltage SF6 circuit breakers, transformers neutral point discharge gap and spare parts, such as Xinjiang outdoor high voltage circuit breakers, common are low-voltage circuit breakers and vacuum off: Circuit Breakers for AC voltage 1200V, 1500V DC voltage circuit plays off, control or protect low-voltage circuit breakers and other electrical effects are an important part of the electrical industry in Gansu outdoors high-voltage circuit breakers, in the machinery industry is the basis for matching pieces, in the distribution system voltage switchgear mainly consists of a variety of low-voltage circuit breaker components, functions and performance of low-voltage circuit breaker is essential for low voltage switchgear plays the role of power generation equipment issued by more than 80% of electrical energy is allocated for use by low-voltage circuit breakers for each additional 10,000 kW of power generation equipment, various types of low voltage circuit breakers about 20,000 or so a complete set. In the industrial automation systems, also by the various control panels, consoles, controllers and other products consisting of low voltage circuit breakers. Chinese low-voltage circuit breaker industry since 1949 in the afternoon, in some repair, basic electrical plant on the simple assembly and gradually developed into independent design, production industry, to 1979 a total of more than 600 manufacturing enterprises, through 1985 to 1986, 1990 to 1991 two Development Summit, in 1995 the industry has low voltage circuit breaker manufacturers about 1500 Qinghai high-voltage circuit breakers high voltage circuit breaker _ _ Huayi Electric Power provides Xi'an 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 from Xi'an Huayi power plant. The company excellence work attitude and constantly improving innovative ideas will lead Huayi power and you hand into the brilliant, for a better future!
