High Voltage Switchgear

1. Overview of Gmini Environmentally Switchgear,High Voltage Switchgear

Gmini is an environmentally friendly switchgear with air-based insulation. It solves the dependence on main insulation materials such as SF6 and epoxy resin. It is based on the long-term practical experience of GZS1k switchgear, and comprehensively considers the user’s experience in medium voltage switchgear. The specific requirements are also a unity of long-term operating experience and innovative technology
This switchgear meets the standards of IEC, GB, etc. It has the interlocking function of preventing the push-pull circuit breaker trolley with load, preventing misdivision and grounding switch, and is a power distribution device with superior performance.

2. Purpose of Gmini Environmentally Switchgear,High Voltage Switchgear

It is widely used in power plants, small and medium-sized generators to transmit power, industrial and mining enterprises, power distribution, and secondary substations of power systems, such as power receiving and transmission, and large-scale high-voltage motor starting, etc., for control, protection, and monitoring.
