Lrbt-363/420/550
1. Product Description
This series of current transformers is mainly for GIS fully enclosed combination of appliances, CT is an independent unit.CT unit primarily consists of a secondary coil, shell, insulating board, and rain cover, after SF6 leakage detection and related electrical performance test factory, GIS manufacturers do not need to assemble the CT in the factory, directly into the GIS can be mounted on the CT unit, easy to install, reliable performance.
2. Main features
Primary insulation medium: SF6 or mixed gas;
Secondary insulation medium: PET polyester film;
Applicable places: indoor or outdoor;
Installation: Vertical or horizontal installation;
Coil fixing method: casting type;
Coil installation method: external type, with a waterproof layer;
The secondary outlet box has an aluminum alloy structure, dust-proof, waterproof, breathable sealing structure that meets IP55 requirements.
