![]() This allows the duct bank to be quickly pre-assembled outside of the trench. These spacers can reduce the electro magnetic field at location up to 57%.įabricated Duct Spacers that are designed and manufactured to your exact specifications are available. We also offer Low EMF (Electro Magnetic Field) Wunpeece Duct Spacers, originally designed for the Los Angeles Department of Water and Power. For all types of duct in many duct bank configurations.Designed for use in concrete encased duct banks.Easy snap-in design halves labour needed. ![]() Custom Spacer Units assembled at no additional cost.The standards for this project call for additional rebar, both horizontally and vertically, when running under a roadway (high. The conduit in the duct bank is Schedule 40 PVC. Call us at one of our offices or send us a message for more information! Wunpeece Duct Spacer I have an underground concrete duct bank that will be installed 2 feet under a roadway (top of duct bank to grade), in an industrial facility, for a very good distance. Power Plant Supply Company is pleased to offer you their high quality products. Since its start in 1973, Underground Devices has been a leader in the design and production of duct spacers. The duct spacer is used for underground encasement of conduit/nonmetallic cable racking for use in power and communications manholes. Duct banks may wearing cable a short distance, such as under a road or longer distances, such how carrying electrical power from ampere power generative data to transmission rail, industrial and publication facilities. It actually makes us look good, that the contractor can only find one thing we've "overdesigned" and it doesn't amount to anything.Underground Devices manufactures duct spacers and conduit supports. The cables are housed into PVC pipe named conduits, which are then encased in steel reinforced concrete. So we laugh, and say put it in per design. ![]() So we have them quantify the amount the owner will save, and it invariably comes out to $5000 or $10,000. Side note: Whenever we have a VE (Value Engineering) phase on a project, the first thing the contractor wants to eliminate is duct bank reinforcing. Concrete formwork must be erected around the installed conduits. ![]() There's no real design, but I have used the reinforcing to span the duct bank over a temporary trench. They're reinforced with #4's around the perimeter at 12 inch spacing and #4 ties at 24 inch centers. There's a lot of casual concrete (waste concrete, thrust blocks, foundation extensions, etc.), but if the backhoe operator sees red, he's been warned. There's a lot of reasons that don't hold up to close examination, but bottom line is, that if you're in a water or wastewater treatment facility, you're likely to be digging a trench through it or a hole into it. We reinforce electrical duct banks and require them to be red. ![]()
