ABB Unigear with single busbar system Breaker AIS ABB MV Products

MEDIUM VOLTAGE, ARC-PROOF, UNIGEAR AIR-INSULATED SWITCHGEAR

Unigear Air-insulated switchgear, ABB’s medium voltage air-insulated switchgear, is the result of ABB’s global know-how integrated into a single technological solution and is also ABB’s answer to the range of solutions demanded by global markets. The switchgear complies with IEC 62271-200 standards. ‘Made in ABB’, UniGear comes with the same design and quality standards across 5 continents, and offers the best solutions for all installations including power plants, power distribution substations, compact Motor Control Centers, double-level, duplex and special-unit switchgear.

Salient Features

• Metal-clad, four-sided internal arc-proof construction (IAC AFLR)
• Designed in conformance with the highest in class for minimum Loss of Service Continuity – ‘LSC-2B with metallic partitions’
• Constructed with pre-galvanized sheets without welding points, making it the most reliable switchgear in its range
• REF542 and other high-end communicable relays offer intelligent solutions for all installation requirements
• It is virtually maintenance-free and all circuit breaker operations can be carried out with the door closed
• Earthing-switch is provided as an option. It is rated for full making capacity and is provided with safe and reliable position indicators
• All compartments can be accessed from the front, hence the switchgear can be placed against the wall
• The switchgear is provided with conventional or integrated protection and measurement systems
• It is fitted with conventional instrument transformers or new generation sensors

APPARATUS WHICH CAN BE INSTALLED IN UNIGEA R SWITCHGEAR

VACUUM CIRCUIT-BREAKER – CASSETTE VERSION

• Circuit-breaker for all fields of application
• Vacuum Interrupters, using radial magnetic field contact system, rotate arc column over the complete contact periphery  to give the best current-interruption performance at all current values
• Epoxy resin poles for greater protection of the interrupters
