110kV Current Transformer oil immersed outdoor single phase can be used in 123/126 power system.

Multi designs can satisfy most special environment, such like high altitude and large temperature difference.

Dead tank is a traditional design which has mature technology, rich operation experience, good stability and  low cost.

Live tank is a new and popular design, it is suitable for big current ratios, less material waste, high technology  difficulty, good electrical field, compact structure and strong dynamic thermal ability.

Both of them we have rich manufacturing and operating experience more than 10 years.

Presently our 110kv CT has been sold and operated in more than 20 countries, also we get most bidding in China State Grid Company, high quality and  stable operation make us deeply loved by end users.
