Today‘s high voltage power transmission must not only meet a high degree of reliability, the products must also be designed to be efficient and durable.

Harnessing its many years of experience in developing and producing switching devices in voltage levels ranging from 72.5 kV to 420 kV, R&S can offer high-quality and reliable disconnectors, earthing switches and motor drives.

Voltage levels: from 72.5 kV to 420 kV
Rated current: up to 4,000 A

High voltage disconnector

Benefits that speak for themselves

Achieve highest efficiency levels
All of our products incorporate state-of-the-art technologies based on the highest quality standards. The switches disconnect networks in an almost powerless state and offer minimised contact resistance and friction. Thanks to the switches’ technically sophisticated design, stability when opening and closing is guaranteed at all times.
Simplify maintenance
R&S offers comprehensive aftersales services. Our highly qualified employees are renowned for their high-quality work and are happy to carry out servicing for you directly on your premises. We also offer you the option of training your own staff, so that they can perform installation and inspection work independently.
Increase your system’s reliability
The switches are highly reliable even in the most challenging of environmental conditions, including those encountered in coastal applications, in areas with high temperature fluctuations and in places where there is a high probability of icing.
Save time and hassle
From consulting and designing, to installation, the aftersales service and spare parts supply, our experts guide you through the entire product lifecycle.
Cut your investment costs
The sturdy and corrosion-resistant design, combined with the high level of mechanical resistance against seismic or electrodynamic forces, allows for a long service life of up to 40 years and cuts your investment costs.

The project shows that R&S SERW is able to quickly and flexibly respond to the customers requests and deliver a special-made and highly efficient solution. The flexibility combined with our high-quality products and many years of experience form a unique selling proposition against our competitors and make sure our company remains equipped for the future.

We tailor our solutions to you

R&S produces horizontal, vertical and pantograph disconnectors, as well as earthing switches and motor drives. Depending on the application in question and customer requests, we offer single-phase, double-phase and three-phase versions. Our flexible Engineering and Design Department will find the perfect customised solution for you.

Horizontal disconnector

- Used to ensure that an electrical circuit is completely de-energised for servicing or maintenance
- Single-pole, double-pole or three-pole
- Each pole consists of a frame and two supporting insulators that the main blade is mounted on

Pantograph disconnectors

- Used to ensure that an electrical circuit is completely de-energised for servicing
- Minimal space requirements
- Single-pole, double-pole or three-pole
- Each pole consists of one support insulator, one rotating insulator, the pantograph mechanism and a counter contact

Vertical disconnectors

- Used to ensure that an electrical circuit is completely de-energised for servicing or maintenance
- Single-pole, double-pole or three-pole
- Each pole consists of a frame, one rotating insulator and two support insulators that the main blade is mounted on

Earthing switches

- Used to earth the residual charge after the line is disconnected from the source
- Single-pole and three-pole versions available

Motor drives

- Local, remote and manual control
- Anti-corrosion heating
- Mounted on special tables or directly on the frame
- Control voltage: 230 V AC, 220 V DC, 110 V DC, 60 V DC
- Motor voltage: 400 V AC, 230 V AC, 110 V DC, 220 V DC
- On / off / intermediate / advanced signalling
