Mining IndustryIn certain electrical installations, PVC coated conduit may be the best replacement for metallic conduit – particularly installations found underground.

The effects of corrosion in electrical and electronics systems in modern mines are often overlooked; however, the harsh environment of the mining industry often causes electrical equipment to fail over time. Calbond® offers a complete line of PVC coated conduit, fittings and conduit accessories in both galvanized rigid steel and rigid aluminum for the protection of electrical conduit systems in highly corrosive environments.  Additionally, the ease of installation and the unit cost of materials makes PVC coated conduit an obvious choice for the budget-conscious contractor. All of our products are UL-Listed and NEMA RN-1 compliant with no exceptions.

  • The corrosive environment of the mining industry limits the lifespan of the processing equipment and as a result, decreases production and endangers the lives of employees within the mine
  • Aerobic and anaerobic microorganisms present in mining water also contribute to the extremely corrosive environments. Aerobic species produce sulfuric acid, making the environment very acidic. Anaerobic microorganisms reduce sulfate and sulfides by using available hydrogen and producing hydrogen sulfide (H2S)
  • PVC coating is available on galvanized rigid steel and aluminum conduit
  • UL® Listed and NEMA RN-1 compliant with no exceptions
  • UL6 Listed with both zinc and PVC as primary coatings, providing two layers of corrosion protection
  • UL PVC adhesion performance tested (DYJC E226472), where conduit is sequentially subjected to air oven conditioning exposure test and resistance salt spray (fog) and adhesion test of ANSI/UL6
  • Specially formulated urethane internal coating provides the longest available product lifecycle
  • Proven to provide corrosion protection at a fraction of the cost of stainless steel conduit
  • Broadest product offering for corrosion protected conduit systems
