ABB showcases new compact GIS at Hannover

Em News Bureau ,  Tuesday, May 22, 2012, 11:43 Hrs  [IST]

new compact GISABB has announced the launch of its new generation 420kV Gas Insulated Switchgear (GIS) during the Hannover Fair, Germany, April 23-27, 2012. The new design reduces product volume (width x depth x height) by up to 33 per cent compared to its predecessor resulting in a considerably smaller footprint, a statement by ABB said.

The compactness of the unit makes it ideally suited for installations where space is a constraint and also reduces the amount of SF6 (sodium hexafluoride) insulating gas requirement by as much as 40 per cent making it more environment-friendly.

The new GIS can be factory assembled, tested, and shipped as one bay in a container instead of multiple assembly units, saving site installation and commissioning time by up to 40 per cent compared with traditional designs. Frontal access to drives, position indicators and service platforms enable easier operation, inspection and maintenance. Standardized modules and connection elements also enable flexibility in terms of configurations and building optimization.

The product features a fast single interrupter dual motion circuit breaker and has been designed for current ratings up to 5000A. It is capable of providing protection to power networks with rated shortcircuit currents up to 63kA.
