In 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.

Why Calbond?

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)
