5 Design5.1 GeneralThe Sabre VREa is a extensible RMU comprising of a tee-off vacuum circuit breaker and two fault-make load break ring switches contained within a common SF6 gas insulated stainless steel enclosure. The unit is suitable for both indoor and outdoor applications and can be used as a freestanding unit.

5.2

Stainless Steel Gas Enclosure

The gas enclosure is manufactured from stainless steel and fabricated utilising automatic 'robot welding' techniques to produce consistent leak- free equipment.

5.3

Housing

The housing of the Sabre VREa is fully treated; using zinc coated steel and electrostatically applied oven cured paint, to resist weather and pollution attacks.
