Champion Fiberglass electrical conduit is a lightweight, durable option that provides lasting savings when compared to other materials. Compare electrical conduit types including aluminum electrical conduit, steel conduit, galvanized steel conduit (GRC) and PVC conduit to fiberglass reinforced epoxy conduit (RTRC). The field is busy-but there’s only one spot for number one. See how fiberglass conduit stacks up to the competition in crucial areas like weight, corrosion resistance and installation cost. Cable Fault Fiberglass conduit will not melt or weld the wire to the inside of the conduit under fault conditions as can happen with PVC, steel and aluminium conduit. Not Affected Melt/Fuse Melt/Fuse Weld Weld Weld Toxicity/Halogens Fiberglass conduit does not release toxic halogens (i.e. chlorine and bromine) when burning. No Yes Yes No Yes No WEIGHT COMPARISON (SW IPS – lbs./per 100 ft., approx.) Fiberglass conduit offers the lowest weight and is still very rigid. 3 ⁄ 4“ 17 (SW) -40° to +230° +40° to +150° +40° to +150° Handling in Low Temperatures Fiberglass conduit has been shown to retain its properties at low temperatures allowing year round installations. Excellent Brittle Brittle Excellent Excellent Excellent GRC, PVC-COATED & ALUMINUM SPACING SUPPORT SPANS Champion Fiberglass support spans are UL listed. Conduit listed for support spacing other than shown in National Electrical Code (NEC) Table 355 shall be permitted to be installed in accordance with the UL listing. 3 ⁄ 4“ 3 ft. 10 ft. BURN THROUGH (CABLE PULL) Fiberglass conduit is an excellent material for avoiding “burn through” when pulling cable. No No No No Yes Yes Using PVC Jacketed Cable Fiberglass conduit offers one of the lowest coefficient of friction available today for conduit systems. It is completely resistant to any of the current pulling lubricants corrosive properties. 0.55 0.25 0.38 0.55 0.90 0.90 CONDUCTIVITY Yes Yes No Yes No No Excellent Excellent Good Poor Poor Poor (10-5 inch/inch/°F) *The coefficient is .7 for the steel and 3.5 for the PVC layer. Because of the broad difference between the two materials, adhesion is severely affected during temperature contraction and expansion. 0.65 1.3 1.5 3.4/0.65* 3.4 3.4 200 50 200 200 50 50 EMT NECA LABOR INSTALLATION RATES (Normal installation hours per/100 ft) (REF: 2025-2026 NECA Manual of Labor Units) *Reduce labor units by 10% for 20-foot lengths 3 ⁄ 4“ FIELD HANDLING Due to its light weight, ease of cutting and integral bell, fiberglass conduit is very easy to install.
