Switchgear are electrical switches that are used in large electrically controlled power systems to control, protect and isolate the electrical equipment. These devices helps to de-energize equipment to allow work to be done and to clear faults downstream. The complete circuitry is enclosed in a metallic casing to line up the assembly which is fabricated by using industrial grade materials which make them capable to withstand environmental impacts.Switchgear can also be used in transmission and distribution systems as well as in medium to large sized industrial facilities. These are connected directly to the main supply system to prevent damages in case of current overload.
