Metal Clad Switchgears
Designed with the innovative technology of Laleli CE engineers, the UMC Series Metal Clad switchgears are produced in accordance with IEC standards for use in primary distribution systems, industrial plants and infrastructure installations up to 36 kV. Medium voltage Metal Clad switchgears are notable for their high current, power, short circuit withstanding and breaking capacities and withdrawable VCB design. Laleli CE Metal Clad switchgears are opted for in the national and international markets due to design flexibility compatible with different specifications.
