The switch is designed to perform switching operations (switching on and off) under specified conditions in normal and emergency modes in networks of three-phase alternating current of frequency 50 Hz with rated voltage of 110 kV with earthed neutral.
The switches consist of three poles (columns) with arc-quenching chambers, a common galvanised frame and a spring drive. The switches are simple and reliable in operation. Additionally, the switch can be equipped with a maintenance platform, control and monitoring cabinet, digital control and condition monitoring system.
