Bushing Current Transformers for 23kV C-GIS
About the Product
Widely used by public utilities and private sectors, these epoxy-cast multi-ratio bushing current transformers (BCTs, or bushing CTs) are typically installed in 23 kV C-GIS (cubicle-type gas-insulated switchgear) for use with measuring or monitoring instruments, or protective relays. Insulated with Araldite® epoxy resin, these products are characterized by superior moisture resistance, excellent electrical performance, and high mechanical properties.
