This series of current transformers is mainly for GIS fully enclosed combination of appliances, CT is an independent unit. CT unit mainly consists of a secondary coil, shell, insulating plate, and rain cover. After SF6 leakage detection and related electrical performance tests, GIS manufacturers do not need to assemble the CT in the factory; the unit can be mounted directly onto the GIS, ensuring easy installation and reliable performance.
