Enhanced Corrosion Resistance Protects Cabling at the Hoover Dam

Nearly half of this national landmark’s existing wiring-housing conduit had degraded, leaving a two-mile area in need of a conduit that could stand up to the ambient environment. See how a corrosion-resistant conduit system for Hoover Dam ensured top performance despite moist conditions.

When aging conduit threatened the integrity of one of America's most critical power facilities, engineers needed a solution built to last.

Persistent moisture inside the Hoover Dam's penstocks had degraded nearly half of all existing steel and PVC-coated conduit installations, some to the point of exposed wiring. Engineers turned to Champion Duct® fiberglass conduit for a corrosion-resistant replacement that could hold up where other materials failed.

In this case study, you will learn:

  • How Champion Duct simplified installation across a two-mile conduit replacement project
  • Why fiberglass outperformed steel and PVC-coated conduit in a high-moisture utility environment
  • Why the Hoover Dam engineering team is still relying on the same Champion Duct installation 26 years later
