ABB Australia  announces the launch of a new vacuum tap changer designed for transformers up to 70 MVA size.

Launched at the ABB Automation and Power World Australia 2012 on the Gold Coast, Type VUBB tap changer is a new development milestone for ABB with the design based on the construction philosophy that minimal moving parts combined with proper material selection minimise the risk of mechanical failure.

Type VUBB tap changers are designed with a focus on cost reduction and extended lifetime.

Fulvio Granata, head of Transformers for ABB in Australia explains that the new VUBB is a compact on-load tap changer that will particularly assist power utilities in their efforts to reduce maintenance as it is based on vacuum technology, which has longer service intervals when compared to conventional arc quenching technology in oil.

Vacuum technology delivers several benefits including improved breaking capacity, increased contact life and reduced maintenance. Designed for both cover-mounting and yoke-mounting arrangements, the VUBB will initially be manufactured at ABB's new state-of-the-art factory located in Ludvika, Sweden.

Additionally, ABB will also be demonstrating the operations of type UZF tap changer on a small power transformer at the event.

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.
