LGBJ-132(110,66) Outdoor organic insulation 66kv current transformer transformer
LGBJ-132(110, 66) Outdoor organic insulation 66kv current transformer
Feature
1,It is organic insulation type product. The external insulation is silicone rubber petticoat.
Electric field evenly distributed, partial discharge small amount and stable. Small dielectric is loss
2, The current ratio can be changed easily by change the connection method in shielding enclosure to facilitate the realization to series or parallel connection.
3, All parts, such as stainless bolts. Name plate are rust-free all the time.
4, The product has no oil, no ceramic, no gas.
