Fiberglass Conduit Comparison and Specifications

This technical report presents a detailed comparison of fiberglass conduit against other materials such as PVC, galvanized rigid steel, and aluminum. It outlines the advantages of fiberglass conduit, particularly its performance under cable fault conditions, where it does not melt or weld wires inside the conduit. The report details the toxicity levels of various materials when burned, highlighting that fiberglass does not release toxic halogens. A weight comparison shows fiberglass conduit as the lightest option while maintaining rigidity. The temperature range for fiberglass conduit is noted to be from -40°F to +230°F, indicating its suitability for year-round installations. The report also includes information on support spans for UL-listed fiberglass conduit and compares its burn-through resistance, coefficient of friction, conductivity, and UV stability against competing materials. Additionally, the ease of installation due to fiberglass's lightweight and cutting properties is discussed, along with its memory retention after impact.
