ABB wins $23 million order to modernize Ukrainian power grid

High-voltage circuit breakers to help strengthen power transmission network

Zurich, Switzerland, Nov.17, 2011 – ABB, the leading power and automation technology group, has won an order worth more than $23 million from NPC Ukrenergo, Ukraine’s national power grid operator, to supply more than eighty sets of live tank circuit breakers rated at 110, 330, 500 and 750 kilovolts (kV) to be installed in seven 750 kV transmission substations.

The circuit breakers will replace air blast-type circuit breakers that have been in operation for nearly four decades. The circuit breakers will be replaced in three phases, starting in 2011 and to be completed in 2014. ABB will also supply control cabinets with bay control devices for the circuit breakers, along with an online condition monitoring system built on the company’s latest substation automation technology.

ABB’s ultra-high voltage 750 kV circuit breaker has many innovative features such as a single operating mechanism per pole, instead of two found in conventional breakers. They are based on the latest technology to provide greater reliability, lower maintenance requirements and cost benefits. The shift from air blast technology also eliminates the need for air compression facilities.

“This new equipment will help in the modernization of the Ukrainian power network and improve grid reliability and efficiency,” said Giandomenico Rivetti, head of ABB’s high-voltage products business, a part of the company’s Power Products division. “It is yet another example of how ABB technologies are helping countries to strengthen their power infrastructure.”

Earlier this year, ABB signed a contract with Ukrenergo to supply 44 sets of 750 kV SF6 circuit breakers. Both projects are part of Ukraine’s program for modernization and upgrade of its power transmission network.

ABB (www.abb.com) is a leader in power and automation technologies that enable utility and industry customers to improve performance while lowering their environmental impact. The ABB Group of companies operates in around 100 countries and employs about 130,000 people.
