A graduate from the Red River Community College Business Administration Program in 1989, I went into the labor force and joined Barkman Concrete in 1991. I worked in their transportation department until 1997 when I changed careers and worked in the agriculture industry until 2008 when I again joined Barkman as a sales representative for their precast trench division.
Barkman joined ESAM in 2012 and have utilized our joined efforts within the group by attending the IEEE trade show with other member organizations in 2016 and are already planning a team effort at the 2018 show in Denver, CO.
Our trench division has allowed me a resource to provide energy distribution solutions in substation designs. We have been providing this product within the oil and gas market, the wind energy market and the hydro-electric field for the past 25 years.
Our market reach is mainly to the entire North American continent, but that being said we have had projects in locations as far away as Madagascar.
One of the greatest challenges we see in the area of underground electrical distribution is heat generated management. When natural dissipation of the heat is not enough to keep a working environment for the cables, methods need to be designed to deal with the extra heat. We work closely with a cable system provider that has patented a design whereby they maintain a free air rating within the underground trench system without resorting to costly steel grated covers. This allows the cables to be housed in a well-protected environment and run at maximum capacity.
All road crossing trenches are designed as a minimum to the CSA – S6 Bridge Code. As such, all load ratings on these units are designed as CL-625 able to withstand a loading of 39,000 lbs per axle driven in any direction over the units, considerably more robust than the typical H-20 standard traditionally required on trench designs.
