When using outdoor insulators, they must bear the influence of many factors, such as electric field strength, atmospheric conditions, mechanical stress and use environment. These factors are all at the same time, and the severity of the effect and the situation of the effect are closely related to the type and structure shape of insulators. Line insulators are subject to tension stress determined by conductor weight and tension of conductor, and changes in wind, ice and temperature will also increase the tension. Insulators may also withstand a variety of transient loads. Vibration or swing of conductors will make the insulators withstand a vibration load. In natural environments such as hurricanes, earthquakes, Ice Shedding of conductors, or artificially fired shots, insulators will bear an impact load.
As one of the important equipments of transmission lines, suspended insulators play an important role in insulating suspended conductors and towers. Suspended porcelain insulators are used in high voltage, ultra-high voltage and ultra-high voltage transmission lines all over the world, providing reliable guarantee for the safe operation of transmission lines in various countries.
Suspension porcelain insulators are divided into two types: AC insulators and DC insulators. The www.qinhuandaobanjia.cnwww.chengshidiaos.cnwww.penquandiaosu.com.cnwww.hanbaiyulangan.cn
