Wenzhou XiFa Electric Power Equipment Co., Ltd is an experienced manufacture to produce 33kv high voltage single phase potential transformer and current transformer. Wenzhou XiFa uses high quality resin to achieve a better performance on insulation, such as long term operation under high voltage without breakdown or partial discharge. Each 33kv high voltage single phase potential transformer is necessary to cast epoxy resin under vacuum circumstance to achieve a longer service life to 20 or 30 years. Before delivery, the basic technical specification is essential to measure such as Power frequency withstand voltage, partial discharge, insulation resistance, accuracy, polarity, and temperature rise.

To produce a reliable 13.8 kv single phase potential transformer in substation, Wenzhou XiFa Electric Power Equipment Co., Ltd adopts premium CRGO electrical steel as the main material of core to reduce the loss value and improve the accuracy class, and high strength enamelled copper wire as the main material of coil to ensure turns ratio and turn to turn insulation through precision winding. Ever more, each 13.8 kv single phase potential transformer in substation adopts the producing process of epoxy resin vacuum casting to make an overall solidified structure that is not easy to absorb moisture, which is suitable for hot, humid and dusty environments.

To well match the working environment in the sf6 ring main unit, Wenzhou XiFa Electric Power Equipment Co., Ltd produce and supply the 11kv three phase metering potential transformer pt. It is dry type or epoxy casting which has a three phase integrated design to match the compact environment in sf6 gas insulation switchgear and achieve a better performance on product installation and insulation. Meanwhile, the 11kv three phase metering potential transformer pt equips internal fuses to allow the potential transformer survived from short circuit and over load.

Wenzhou XiFa Electric Power Equipment Co., Ltd has more than 10 years to produce epoxy resin potential transformers and current transformers, such as a 25 kv instrument electromagnetic pt potential transformer. The 25kv potential transformer is for specific regional grid voltages, such as North America and some American countries. Although it is labeled 25kv instrument electromagnetic pt potential transformer, the standard adopted is 24kv. Wenzhou XiFa Electric Power Equipment Co., Ltd has a variety of mature design solutions on accuracy, insulation and mechanical strength to achieve a 25 kv instrument electromagnetic pt potential transformer that has a longer service life.

Wenzhou XiFa Electric Power Equipment Co., Ltd is an experienced manufacture to produce medium voltage resin cast potential transformer in switchgear. The company has mature technical solutions in medium voltage resin cast potential transformer design, insulation treatment and precision control to fulfill electricity demands of terminal users. The raw material used on each medium voltage resin cast potential transformer, such as cold rolled grain oriented silicon steel sheet and insulated enameled copper wire, allow the potential transformers achieve a better performance on efficiency and electrical conductivity.

WenZhou XiFa Electric Power Equipment Co., Ltd is a professional manufacture to produce polymeric and porcelain drop out fuse as the technical specification from terminal users. WenZhou XiFa is capable to produce Polymeric 11kv 33kv Drop Out Fuse Set 22kv or the maximum working voltage level between 12kv to 40.5kv power system with 50 or 60 Hz Rated Frequency. Meanwhile, WenZhou XiFa also supply 24 hour technical support and customer oriented service such as product selection and installation guidance.
