RTRC CONDUIT
Reinforced Thermosetting Resin Conduit (RTRC) Thailand’s first epoxy fiberglass conduit manufacturer, certified to NEMA TC-14 and TIS standards.
Product overview
Reinforced Thermosetting Resin Conduit RTRC
High-performance composite conduit engineered for underground and infrastructure cable protection applications. Manufactured from reinforced thermosetting resin with fiberglass reinforcement, providing superior mechanical strength, corrosion resistance, and long-term durability.
Compliant with NEMA TC14 and TIS 2518-2557 standards. Available in sizes from 1 1/4” to 6”, with lightweight construction, excellent impact resistance, UV protection, and operating temperature range from -40°C to 110°C.
Key performance characteristics
Built for long-term cable protection.
Performance comes from the epoxy matrix, continuous E-glass reinforcement, controlled filament winding and smooth internal surface.
