Giant transformers complete journey across Manitoba roadways

WINNIPEG, Man. -- Three giant transformers have arrived at their new home at Manitoba Hydro's Riel Station after a three-night trek across provincial roadways.


WINNIPEG, Man. — Three giant transformers have arrived at their new home at Manitoba Hydro’s Riel Station after a three-night trek across provincial roadways.

The transformers – each valued at more than $5 million and weighing more than 175,000 kg when prepared for transport – are being installed as part of the utility’s reliability improvements on its 500,000-volt line linking Manitoba to Minnesota.

The transformers were transported using a special 320-tire self-propelled modular trailer (SPMT) that was brought to Manitoba especially for the move. A special 144-km route, designed to avoid tight city streets and narrow overpasses, was used for the journey.

The SPMT used to move the transformer measured just over 34 metres in length and approximately 7.5 metres wide. The 320 tires on the SPMT were used to allow the tremendous weight of the transformer to be distributed evenly over a large area of road, preventing damage to the concrete and asphalt. The move was conducted at a speed of about five kilometres per hour. Officials say this was the first time SPMTs have been used in Manitoba.

Six semi-trailers were also required to move the accessories, such as bushings, coolers and other ancillary equipment, needed to complete each transformer once on-site at Manitoba Hydro’s Riel Station. Six semi-tanker trucks also moved the 112,000 litres of insulating oil required to fill each transformer.
