Medium-voltage components

For high availability and efficient power supply!

Highly available and efficient power supply with vacuum technology

Medium-voltage power distribution

Vacuum technology – prepared for all requirements

A high level of availability and long service life – these are the determining criteria when selecting medium-voltage switching devices. That’s one of the reasons why more than 70 percent of all network operators choose vacuum switching technology today. Hermetically sealed vacuum interrupters guarantee consistently high quality throughout the entire product lifecycle. There’s little wear, given the extremely low arc voltage, just like the minimum energy conversion in the contact gap – thanks to the short arcing time. The very low contact resistance prolongs the product’s service life and keeps maintenance requirements to a minimum. 

Our medium-voltage components are comprehensively based on vacuum technology and comply with all current national and international standards. These devices can be used in almost all medium-voltage power distribution applications and can be adapted for other specific requirements as appropriate. You’ll benefit from a high level of reliability, flexibility, and cost-efficiency.
