ABB wins $20MM power products order in Ukraine

ABB, the leading power and automation technology group, has won an order worth $20 million from NPC Ukrenergo, Ukraine’s national power grid operator, to supply 44 sets of SF6 (sulfur-hexafluoride gas) circuit breakers rated at 800kV (kilovolts) to be installed in five 750kV transmission substations around the country.

These modern circuit breakers will replace outdated air blast-type circuit breakers that have been in operation for nearly four decades. ABB will supply the equipment and provide technical training. The circuit breakers will be replaced in four phases, starting in 2011 and ending in 2014.

ABB’s state-of-the-art ultra-high voltage 800kV SF6 circuit breaker has innovative features that include a single operating mechanism per pole, replacing the two found in conventional 800kV breakers. This provides greater reliability, reduced initial costs and considerable reductions in maintenance costs. The shift from air blast technology also eliminates the need for air compression facilities.

ABB will also supply control cabinets with bay control devices for the circuit breakers, along with an on-line condition monitoring system built on ABB’s substation automation technology.

“This technology will help strengthen grid reliability and enhance efficiency in the Ukrainian power network, and also saves space,” said Giandomenico Rivetti, head of ABB’s high voltage products business, a part of the company’s Power Products division. “It will also help improve power security and quality.”

Ukraine is one of a few countries in the world with an 750kV network. This project is part of the country's efforts to modernize and upgrade its power transmission network, which includes the refurbishment of 220kV, 330kV and 750kV substations. In 2008, the country received a $200 million loan from the IBRD (International Bank for Reconstruction and Development), which will help fund this project.
