Medium voltage switchboard

Medium voltage switchboard is used for power switching, distribution and metering in medium voltage network or loads. Medium voltage switchboard is designed and type tested according to IEC 62271-200 and IEC 61641 standards. Production quality management is applied ISO 9001:2008 and ISO 14001:2004, ensuring high stability and safety on operation.

Medium Voltage switchboard is widely used in power stations, distribution network of power companies, industry zones, factories and buildings.
