BC Hydro in Vancouver has ordered two of ABB's Dryformer power transformers. The units are based on cable technology that eliminates the need for insulation oil. The two 42 MVA, 64/25 kV units will be supplied by ABB Inc in Canada and manufactured in the ABB transformer factory in Ludvika, Sweden.
The units are scheduled to enter service by October 2002. They will be installed in a new substation to server the developing areas of South Surrey, British Colombia. The environmental characteristics of the new transformers enables them to be installed in highly populated urban areas where high safely standards must be maintained and in environmentally sensitive areas where the risk of oil contamination would make traditional, oil-insulated transformers untenable.
ABB has secured a $17 million contract to design and build a 340 km power transmission line, complete with a 282 km power distribution network, as part of an initiative to upgrade the rural electrical infrastructure in Laos. The order, placed by Electricité de Laos, is due to be completed within two years. The project is financed by the Asian Development Bank.
The undeveloped rural infrastructure in Laos is considered a major constraint on rural economic growth and the reduction of poverty. The project, which will expand the power grid in the northern Laos provinces, will increase by three per cent the number of electrified villages in the country.
Under the terms of the contact, ABB will erect and commission a 340km, 115kV double circuit transmission line and a 282 km, 34.5 kV distribution network, including distribution transformers. ABB engineers from Spain and Germany will carry out the work.
