Advantages of purchasing disconnectors SERW

Disconnectors are used for visible switching and disconnecting of electrical networks without current load.

The portfolio of products for the transmission network includes disconnectors and earthing switches for voltage levels from 245 kV to 420 kV.

We supply single-pole disconnectors in configurations without an earthing switch, with one earthing switch or with two earthing switches.

To control disconnectors and earthing switches, we use our own drives ensuring reliable and safe operation of the devices.

Drives for controlling disconnectors and earthing switches are located on supporting structures of individual devices.

The devices are controlled by an electric motor or manual drive using a kinematic chain.

All development is carried out by highly qualified experts with many years of experience

Thanks to their extensive experience in designing and manufacturing disconnectors, our products have gained a reputation for reliability and long service life.
