AUTHORISED STOCKIST OF COMPTON GREAVES SF6 RING MAIN UNIT

Ring Main Unit

SABRE Range – SF, Gas Insulated Vacuum RMU
Product Overview

The SABRE range of RMU combines the most advanced Vacuum & SF, technologies to meet the modem day requirements. It is fully extensible and highly flexible unit used in a wide range of applications including distribution switchboards, transformer substations, ring distribution networks and HV Connections to industrial & commercial sites. The units are developed to suit customer requirements for connection, supply, protection and sectionalising with remote operation.

The SABRE RMU’s ensure protection in the form of a circuit breaker being monitored & controlled by a self powered numerical relay. The sectionalising is enabled through ring switches.

Salient Features

  • Stainless steel enclosure fabricated by automatic robotic welding.
  • Isolation in clean SF „gas for Ring switch & in vacuum for CB.
  • Suitable for Indoor& Outdoor application.
  • Common Switching chamber with Vacuum Tee off circuit breaker.
  • Enhanced duty in excess of IEC requirement. I All switch positions have pad-locking & Casten interlocking
  • Internal arc protection including cable boxes.
  • Extensible from both the sides.
  • Fully SCADA compatible unit with remote switching.

Circuit Breaker

The CB comprises of 3 vacuum interrupters, which have a fault-make, fault-break rating. Earthing of the outgoing cable is achieved by the use of CB in series with the off-load disconnector / selector switch. This will enhance the making capacity of the Earth switch.

Ring Switch

These are fault-make load break switches utilising a single break 3 position switches viz., ‘ON’, ‘OFF& tarth’functions.

Operation & Safety

All operating positions and instructions are indicated on the main panel at the front of the unit. Both manual & automated versions are available in SABRE range.

Live Parts are contained within an earthed stainless steel enclosure with positive safety interlocks on all switch / selector positions ensure operator safety & prevent incorrect operation.
