General

 

OMR is a ring main unit for the secondary distribution network. RMU(OMR) can be supplied as a 3 or 4-way standard configurations with additional equipment according to customer specification. OMR can be supplied in 10 different configurations (Such as CVC, CCV, CVV, CFF, CCC, VVV, CCVV etc) suitable for most switching applications in 12/24 kV distribution networks.

It is extendable and combined with our 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.

This product is in conformity with the standards: IEC62271-200, IEC60420
