    Structure and Characteristics

    This series of current transformers are fully enclosed products cast with polyester resin. The primary and secondary windings as well as the core are all cast in polyester resin, featuring excellent insulation performance and moisture resistance. There is an installation base plate at the bottom or on one side. The secondary outgoing line end is equipped with an anti-electricity theft cover. This series of current transformers are small in size, light in weight and have excellent insulation performance. They are alternative products to the old model ModelLQG-0.5.
