Reliable Connectors and Bushing for Gas Insulated RMU
Zhuhai Comking Electric Co., Ltd., a specialized manufacturer of power distribution components, today announced the availability of key interface components designed for gas insulated ring main units (RMUs) and cable termination applications. The product lineup focuses on operational safety, dielectric integrity, and compatibility with standard switchgear interfaces.
The first highlighted component is the 15kV/630A shielded front connector, engineered for separable connector systems in medium-voltage networks. It features a fully shielded, fully submersible design that ensures safe live-front operation and fault closure. The connector is suitable for both copper and aluminum cables, and its interface conforms to industry-standard dimensions for 15kV class equipment.
Complementing this connector, Zhuhai Comking Electric Co., Ltd. also supplies the Bushing 630A /1250A for gas insulated ring main unit. This bushing acts as a fixed interface between the RMU’s gas-filled tank and the external cable connector. It is rated for continuous currents up to 1250A and short-circuit withstand capabilities, while the mating connector side supports 630A. The bushing’s epoxy insulation and embedded conductive layer provide a reliable gas barrier and a defined earth screen.
For applications demanding additional insulation margin, the company offers the Fully Insulated 15kV Shielded Front Connector. Unlike standard shielded connectors that rely on external air clearance, this fully insulated version incorporates a solid dielectric layer over the entire outer surface, eliminating any exposed conductive parts. It is particularly suited for harsh or confined environments where extra protection against partial discharge and tracking is required.
All three components are factory-assembled and tested for partial discharge, AC withstand voltage, and contact resistance. They are designed to work seamlessly with 15kV gas insulated RMUs, reducing field installation time and enhancing long-term reliability. Zhuhai Comking Electric Co., Ltd. provides technical documentation and installation guides to support utility and OEM customers.
