Product Application
JZZY1-10 combined transformer is a new type of high-voltage electric energy metering device. It is composed of three fully insulated voltage transformers with the same voltage ratio. Phases A, B, and C are connected in series with current transformers with the same current ratio. It is cast in one piece with special low-temperature epoxy resin and seamless silicone rubber is used for external insulation.
