Transformer voltage and current transformers are divided into two categories. Voltage transformer can be used for voltage and power measurements in high-voltage and high-voltage power system towards. Current transformers can be used in measuring the exchange of current exchange measurements and power lines to protect electrical drag degrees. Welcome to inquire ...... Huayi Electric Power Thank you for your attention! Divided by an insulating medium voltage transformer: Dry voltage transformers: the ordinary insulating material impregnated insulating paint as an insulating transformer is used in low voltage level and below; pouring insulation voltage transformer: pouring epoxy resin or other composite material Forming Yan'an 35kv current transformer, and is used in the following voltage levels; oil-immersed voltage transformer: by insulating paper and insulating oil as insulation, is the most common type of construction used in voltage level and below; gas insulated voltage transformer : Baoji 35kv insulated from the gas as the primary current transformer is used in a high voltage level. Typically designed for measurement of low voltage transformer is a dry, high or ultra-high pressure-sealed gas insulated (such as sulfur hexafluoride) transformer is dry. Guss applies to 35kV and below voltage transformers, 35kV or more products are oil-immersed. Tongchuan 35kv current transformers, transformers, 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!
