66kV Oiled Current Transformer Electric Substation Equipment
66kV Oiled Current Transformer Electric Substation Equipment
66kv current transformer we have two kinds, upright and inverted type.
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, good electrical field, compact structure and strong dynamic thermal ability.
Both of them we have rich manufacturing and operating experience.
Optimized designs for external insulation make inner and external electric field distribute evenly without discharge. Two type insulators are offered for user.
1. Composite insulator
2. High strength porcelain insulator
Hermetically sealed stainless steel metallic bellows is installed on the top, which protect the transformer oil from moisture and extend the life time, also there is a oil level gauge on the bellows for observing the changing of oil volume.
The base and secondary box adopt spray painting or hot galvanizing, which gives a high degree of corrosion resistance.
