MediumVoltage Panels
Medium Voltage Switchgear is an integral part of Medium Voltage distribution systems. They ensure proper distribution, protection and control in Power Transformers, medium voltage motors and in the internal networks of consumers. They are equipped with suitable protection relays, surge arresters, etc., to protect the electrical circuits – equipment, as well as with mechanical interlocking systems to protect the users – operators.
The Medium Voltage Panels manufactured by our company consist of individual panels designed for equipment up to 24KV. They are suitable for operation indoors and in normal environmental conditions. Their size and complexity varies according each application.
Their construction ensures the possibility for future expansion – addition of new medium voltage panels. Panels are easy to install, connect and put into operation.
Every Panel is accessible from its front side, through a door secured by safety locks, control unit and mechanical interlocking system. Every switchgear is accompanied with all necessary handles of operation.
