Product Description

Product Introduction
The 35(40.5)kV top bus-bar system (Type C connector series) is a medium/high voltage fully insulated, fully screened bus-bar connection solution specifically designed for bus-bar connections between 35kV GIS system switchgears. The system consists of:

• Type C bushing (206) - 40.5kV 630A/1250A, for cabinet interface
• Type C tee connector (ACD-35(40.5)/) - for branch connections
• Type C cross connector (ACS-35(40.5)/) - for four-way connections
• Bus-bar (ACMx-35(40.5)/mm) - connecting bar, customizable length

The system is suitable for a minimum center distance of 500mm and maximum currents of 630A or 1250A. It adopts a bolted connection structure, and the flexible connection is not sensitive to height errors of the combined cabinets, offering high installation tolerance.

Application Scenarios
The 35(40.5)kV Type C bus-bar system is widely used for bus-bar connections in 35kV GIS switchgear, especially where compact space and installation tolerance are required:

1. 35kV GIS switchgear - For bus-bar series connection, branching or ring connections between cabinets, with minimum center distance of 500mm.
2. 40.5kV gas-insulated switchgear - Provides fully insulated, fully screened bus-bar connection, avoiding insulation risks of exposed bus-bars.
3. Modular GIS systems - Flexible combination of multiple switchgear cabinets using tee and cross connectors.
4. Outdoor and harsh environments - Fully sealed structure, anti-condensation, anti-pollution, maintenance-free.
5. High-current circuits - 1250A capacity suitable for main bus or high-capacity outgoing lines.
6. Space-constrained substations - Short center distance (500mm) design meets compact layout requirements.
7. Retrofit of older GIS - Flexible connection adapts to dimensional deviations between old and new cabinets.
