Oil-Immersed Hair Pin Current Transformer
The LB-type current transformer is an outdoor, oil-paper insulated unit with a vertical structure. The secondary winding sits at the bottom of the product, while the primary winding uses a U-type conductive rod structure, giving it excellent insulation performance. The oil tank is made of cast aluminum with a robot-welded main sealing surface, providing excellent rust and leakage resistance.
