66kV Oil Immersed Dead Tank Current Transformer
66kV Current Transformer Outdoor Oil Immersed Single Phase
Here we have 2 options for your choosing, dead tank (bottom tank) and live tank (top tank)
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.
