Medium Voltage Panels

These panels are installed in industrial plants, for the distribution of medium voltage electricity, they consist of modular compartments that can be coupled and used in transformer cabins for the control and protection of lines, transformers, motors, in the distribution of electricity, in electricity mains distribution companies and in industrial mains
