Lateral expansion busbar connector system product introduction:


The horizontal expansion busbar system is widely used in the combined connection of ring main unit (RMU) and gas insulated switchgear (GIS). It is mainly composed of side expansion bus connectors and inner cone bushings, providing more branches for equipment expansion.


Product execution standards: GB/T8349, GB/T11022


Lateral expansion 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
