LW36-126/145 High Voltage Circuit Breaker

 Live Tank Circuit Breakers from 100 kV to 145 kV

Live tank circuit breakers for outdoor installation are designed for temperatures down to -60 °C and feature the latest technologies in interrupter chambers and spring-operated mechanisms. For example, the latest double motion technology effectively reduces the opening energy byapproximately 65 %.

High Performance

Live tank circuit breakers ensure a high level of reliability every day.

Even under extreme conditions and climates or in highly active seismic areas customers can count on live tank circuit breakers.

Quality

The entire development and production procedures are fully compliant with the latest ISO 9001, ISO 14001 and OHSAS 18001

quality standards. This ensures the high quality of our products and services and is confirmed by regular audits.

Customer Benefits

High reliability even in the coldest regions of the world:

Down to -40 °C with pure SF6 Down to -60 °C with gas mixture

Quick and easy installation and commissioning

Long maintenance intervals
