Among our most challenging contracts was a 6.5-kilometer underground cable installation for Alcatel Canada Wire – Ontario Hydro in downtown Toronto along Lakeshore Boulevard, one of the cities busiest arteries. M.V.MARK INC. carried out all aspects of this project including the excavation, welding, and installing of the pipe, backfilling, cable installing, jointing and terminating, declassifying, and installing of the oil and jacket testing. Also, as a result of keeping traffic disruption to a minimum, M.V.MARKINC. designed a special prefabricated manhole which helped reduce traffic diversions to a minimum.
M.V.MARKINC. specialists are equally at home under the ground or under the water. Between Lotbinière and Grondines, Québec, we installed two 450 kV DC fluid-filled circuits, along with two spare cables, through a tunnel under the St. Lawrence River for Hitachi Cable – Hydro-Québec. Not a remarkable accomplishment perhaps… until you consider that we were required to install over 5 kilometers of cable in one continuous length with no joints whatsoever! This installation, the first in the world of its magnitude, was completed on schedule in just a year. In addition to the high voltage work M.V. MARKINC. devotes the same attention to the commercial and industrial fields: plant additions, plant rewiring, installation of boiler systems, etc. For M.V.MARK INC. no work is too small or too big. All are important to us.
We offer an emergency repair service 24 hours per day, seven days per week, with a prompt response within hours of the breakdown. A very substantial inventory on our premises allows us to tackle just about any type of problem which could arise. We pride ourselves on keeping customer breakdowns to a minimum of time lost. Our equipment fleet is recognized nationally as amongst the most comprehensive in the industry. And if the equipment doesn’t exist – M.V.MARKINC. will build it. For example, we developed a motorized cable reel, which allowed us to lay over 26 kilometers of 25 kV submarine cable from the Ontario mainland to Pelee Island in Lake Erie, again with no field splices.
