630A side expansion GIS 10KV cabinet external interpolation inner cone busbar connector inflatable switchgear insulation

1. product introduction
The side-expanding bus coupling is mainly composed of an insulating jacket and conductive copper parts, and the conductive copper parts are embedded in the insulating jacket. The insulating jacket is made of high-temperature, anti-aging rubber insulation material and has a unique internal design, so that the complex electric field is evenly distributed, resulting in excellent performance and long service life; The conductive copper parts are equipped with spring contact fingers, which have good elasticity. The side expansion bus coupling is suitable for the parallel connection of the ring main unit, provides multi-branch series connection for the expansion of the ring main unit, and is the preferred scheme of the combined ring main unit.
