24KV 630A Screened Branch Separable Insulated Connectors for Bushing Type C
We designed these screened separable insulated connectors for bushing type C (EN 50180/EN 50181) to connect polymeric cables to medium-voltage switchgear and transformers up to 24kV / 630A. They can offer a completely screened and submersible connection.
Features:
- Front Screened Construction: We designed this separable connector to improve safety and protection. It will reduce the risk of accidental contact and ensure operator safety during maintenance or repairs.
- Built-in Capacitance Test Point: We have designed this separable connector with a capacitance test point for quick assessment of circuit status. It also includes the option to install fault indicators for simplifying maintenance and fault detection processes.
- No Minimum Phase Clearance Requirements: There is no need for specific phase clearance requirements for this connector. This feature provides installation flexibility and reduces constraints in space-limited environments.
- Versatile Mounting Options: This separable connector supports vertical, horizontal, or any angle in between for mounting. So, you can use it for different installation configurations and spatial constraints.
- High-Quality Materials: We manufactured these separable insulated connectors from high-quality EPDM and silicone rubber. So, they can provide a long service life and easy installation.
