Compact 12kV MV Current Transformer Three Phase Overhead Line Column Installation
12kV Outdoor Three-phsae Epoxy Resin Type Combined Transformer
Description:
Three-phase combined current and voltage transformer JLSZXW5-12S is combined of 3 CTs and 3 PTs (2CTs+3VTs and etc. available).
Y-Y star wiring. Casted by alicyclic epoxy resin, it is high UV resistance for outdoor environment. The structure is more compact than oil-immersed type, and it is light weight, no oil leakage pollution, maintenance free. It is mainly use for measuring current and voltage, energy metering and smart system management of OHL in the highest equipment voltage of 12kV rated frequency of 50/60Hz.
