General
OMR is a ring main unit for the secondary distribution network. OMR can be supplied in 10 different configurations suitable for mostswitching applications in 12/24 kV distribution networks.
It is extendable and combined with Rockwell own developed technology concept, which is flexible, modular compact switchgear, they represent a complete solution for 12/24 kV secondary distribution networks. OMR have identical user interfaces.
OMR is a completely sealed system with a stainless steel tank containing all live parts and switching functions.
A sealed steel tank with constant atmospheric conditions ensures a high level of reliability as well as personnel safety and a virtually maintenance-free system.
The OMR concept offers a choice of either switch-fuse combination or circuit-breaker with relay for protection of the transformer. OMR can be supplied with an integrated remote control and monitoring unit.
