Take a look at all the types of disconnectors for the distribution network
Our disconnectors for distribution network excel in unrivalled reliability under any conditions thanks to their sophisticated structural design. They ensure stable operation when switching on and off in the most demanding conditions, areas with high temperature changes, and in places with a high probability of frost formation.
Advantages of purchasing disconnectors SERW
True reliability
Disconnectors are used for visible switching and disconnecting of electrical networks without current load.
Comprehensive portfolio
The product portfolio for the distribution network includes disconnectors and earthing switches for voltage levels from 3.6 kV to 123 kV.
Almost unlimited variability
We supply disconnectors in three-pole, two-pole, or single-pole variants, in configurations without an earthing switch, with one earthing switch, or with two earthing switches.
Elimination of safety risks
To control disconnectors and earthing switches, we use our own drives ensuring reliable and safe control of disconnectors.
Robust mechanical construction
The drives for controlling disconnectors and earthing switches are located on supporting structures of individual devices.
Less susceptible to wear
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 a long service life.
