LRBT-72.5/126/145/252/363/420/550
1. Product Description
This current transformer series is mainly used for HGIS combination electrical appliances, CT is an independent unit.CT unit primarily consists of a secondary coil, shell, and rain cover, after SF6 leakage detection and related electrical performance test factory, HGIS manufacturers do not need to assemble CT in the factory, directly into the CT unit can be installed into the HGIS, 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.
