Oil - immersed Inverted Current Transformer (LVB series)
Product Characteristics
LVB series oil immersed inverted current transformer adopts inverted fully enclosed structure which is mainly composed of expander, oil conservator, primary winding, body, porcelain bushing, base and junction box, etc. This series of products can withstand higher primary current, with better sealing and lighter weight. In case of breakdown, the secondary winding can be protected.
