Equipment for Japanese MarketOil-immersed Type Unearthed Voltage Transformer (VT)

Instrument transformers, which transform high voltage into low and easy-to-handle voltage, are used mainly in connection with a supply meter.
Feature
- The main insulation medium of these products is electrical insulation oil. (The Fire Service Act is applied.) We can fabricate these products in conformance with JIS C 1731-2 and JEC-1201 as well as some foreign standards.
10-70 kV unearthed voltage transformers
These products are used mainly for measuring high voltages.
