United Wire & Cable Inc. (UW&C) and Trenwa, Inc. have partnered to supply Maxiamp Underground Cablebus Systems to customers across the U.S. and Canada. Trenwa, Inc. will be the supplier of precast trench as the underground containment for the new system.

The product is an underground power feeder system that maintains a free air ampacity rating below grade. Achieving a free air rating allows the power feeder system to be designed using fewer and/or smaller cables, resulting in less material, labour and space required, versus traditional subterranean power feeder systems, such as a duct bank (wire in conduit) system.
