Leading power and automation technology specialist, ABB Australia announces the launch of its latest generation 245kV (kilovolt) ELK-14 series Gas Insulated Switchgear (GIS) in Australia.

Launched at the ABB Automation and Power World Australia 2012, ABB’s new gas insulated switchgears feature a 40% smaller footprint compared to conventional designs and use 20% less sulphur hexafluoride (SF6) gas compared to the previous generation, enhancing the environment-friendly factor.

The compact design also enables the GIS unit to be delivered as a completely assembled bay, reducing installation time by more than 60% compared to traditional construction. Featuring single phase isolation delivered fully tested and mounted on a frame, ABB’s gas insulated switchgears also incorporate intelligent control and protection equipment in the control cubicle directly at the bay as a smart grid enabling feature.

The GIS unit’s bay design is highly flexible allowing all system configurations including subsequent expansions to be easily and quickly implemented. The design also facilitates more convenient accessibility to the operating mechanisms located in the front of the bay and positioning of the current transformers outside the gas compartments.

Key features of ABB’s ELK-14 series gas insulated switchgears:

  • Designed for a rated voltage of 253kV
  • Can handle rated currents of up to 3,150 A
  • Versions conforming to IEC and IEEE standards protect power networks up to a rated short-circuit current of 50 kA
  • Compact design allows bay arrangement
  • 40% smaller footprint compared to conventional designs
  • 60% less installation time
ABB is the global leader in high-voltage GIS technology, with more than 20,000 bays installed and operating reliably around the world including a GIS unit rated to handle more than one million volts (1,100kV), with a switching capability of 6,900 megawatts.

GIS technology is a compact, modular and robust solution for maintaining reliable electrical power under challenging conditions with minimum maintenance needs coupled with key benefits such as low technical losses and enhanced equipment security. The technology's minimised footprint enables installation in locations with space constraints such as busy city centres and even indoors. ABB’s product range also includes gas insulated switch gears for offshore and mobile applications.

ABB Automation and Power World Australia 2012 is being held at the Gold Coast Convention and Exhibition Centre, October 23-24, 2012 to showcase ABB’s extensive offerings and expertise in power and automation technologies that address the themes of energy efficiency, grid reliability, industrial productivity, lifecycle management and renewables and environment.
