Electric
Rocky Mountain Contractors provides construction and maintenance on a broad range of electric infrastructure. We have extensive expertise with transmission, distribution and substation facilities through 500 kV. We helped design and install the first 69 kV underground transmission on the Montana Power system. RMC has been providing quality service in the electrical industry since the 1960s. We have the training, men and equipment to employ live-line (both hot stick and rubber glove) work practices. From transmission work in rough country to distribution or substation work on industrial sites, RMC has the expertise to get the job done.

Substations
Our substation technicians are familiar with all phases of substation construction. Whether it is relay and equipment wiring or welding the aluminum conductor, RMC employs the very best. We have wired many different manufactures’ equipment such as Switzer, ABB, G.E., Virginia and Delta Star and installed Pascor, S&C, Unicor and Pacific type equipment. Our welders are AWS certified and use the Heli-Arc welding process to insure a smooth, corona free weld that expands and contracts equally with the conductor. Pride of craftsmanship is sure to show in the details of a substation.
