Product name
Support bracket components for ultra-high-voltage GIS circuit breaker

Category

• Component manufacturing and machining
• Precision mechanical processing

Product description
These support bracket components are installed under the main tank of ultra-high-voltage (UHV) GIS circuit breakers. The bracket assembly has a complex structure with approximately 80 distinct sub-components. Manufacturing requires strict control of welding deformation and high precision in riveting and assembly. The bent-plate flange on the bracket is a key interface connecting the upper circuit breaker tank to the lower hydraulic operation mechanism and demands tight flatness and surface specifications.
