Load Break Switches

Ulusoy Electric LBS series gas insulated switchgear components have been specially developed to provide integrated production of medium voltage modular switchgear. The LBS series of gas insulated load disconnectors used in both fully gas insulated RMUs as well as air insulated switchgear which have been type tested in international accredited laboratories. One of the most important differences of the load separators developed by the Ulusoy Electric specialist engineers is that it works with a vertical axis similar to the breaking mechanism. The load disconnector with three poles and two positions does not require gas filling and repair for 20 years under normal operating conditions.
