Screened top busbar connector system product introduction:


Top expansion bus connectors 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.


Screened top 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
