PVC-C High-Voltage Underground Power Cable Duct offers superior heat and flame resistance for demanding power cable protection applications. The chlorinated PVC formulation provides enhanced performance over standard PVC. ## PVC-C Advantages Chlorinated PVC (PVC-C) contains additional chlorine that significantly improves heat resistance and flame retardancy - critical properties for high-voltage cable applications. ## Fire Safety - **Self-Extinguishing**: Material stops burning when flame is removed - **Low Smoke**: Reduced smoke generation in fire conditions - **No Dripping**: Maintains structural integrity under fire exposure ## Electrical Properties Excellent dielectric strength provides reliable electrical insulation, essential for high-voltage cable protection where safety margins are critical. ## Installation Rigid construction provides precise alignment and protection. Jointing by solvent cement ensures secure, leak-proof connections.
