    500kV, 420kV, 362kV, 300kV, 245kV 170kV 145kV 123kV 72.5kV 52kV, 36kV High voltage Voltage transformer, potential transformer,high voltage inductive voltage transformer, station service voltage transformer PT, VT, IVT, SSVT

    JDX-, JDCF- series voltage transformer, outdoor, oil-immersed inductive type, single phase, hermetically sealed, earthed, cascade-type voltage transformer with high accuracy and protective class secondary windings. Used for metering and relay protection, applying to highland area.

    The voltage transformer consists of internal insulation parts, a porcelain insulator, oil, base, metallic bellows. The high-voltage windings are separated into two (or four) parts that are located on two poles of the core. The secondary windings are located in the lower pole of the down core. Three secondary windings are: metering, protective and residual windings. The core is designed to have low flux density. There is an oil drain plug in the base. A set of oil draining device is supplied for three transformers.
