U-type busbar connector system product introduction:
U-type busbar system are widely used in the combined connection of ring main units (RMU) and gas insulated switchgear (GIS). They are mainly composed of T-type connectors, cross connectors, and bus-bar tubes to provide more branches for equipment expansion. the distance and number of connection centers can be flexibly adjusted.
Product execution standards: IEC60502.4, GB/T12706.4
The product matches the C-type bushing in EN50180&50181.
U-type busbar connector system product features:
Molded from safe and environmentally friendly silicone rubber
Has excellent insulation properties, corona resistance and tracking resistance
Reasonable structural design, three-layer post-injection peroxide cross-linking process to reduce partial discharge
Built-in stress control, uniform electric field distribution
The conductive copper price of the top busbar connector is T2 copper tube or copper rod, and the busbar tubes is locked with a busbar clamp.
Suitable for copper and aluminum cables
Quick assembly and simple installation
