LX(Z)K-100 zero sequence current transformer

This type of current transformer is an epoxy resin cast bus type open structure, which is suitable for over-current protection of three-phase cable grounding fault in 10kV and below indoor AC 50Hz lines. During installation, the transformer can be disassembled and divided into two halves, and then combined into one after the cable is installed. The installation is convenient and can be installed without power failure.
