Evaluating material chemistry, thermal dissipation advantages, and international grid modernization standards.
Thermal Resilience Under High Load
Unlike standard UPVC, PVC-C (Chlorinated Polyvinyl Chloride) contains approximately 67% chlorine by weight, pushing its Vicat softening temperature beyond 93°C–105°C. This allows high-voltage and extra-high-voltage underground transmission cables to operate at elevated temperatures without conduit ovalization or thermal collapse.
Self-Extinguishing & Zero Eddy Current
PVC-C has a Limiting Oxygen Index (LOI) of ≥ 40%, classifying it as self-extinguishing with minimal flame propagation. Being completely non-magnetic and non-conductive, it eliminates electrical eddy current induction losses commonly seen in metallic conduits, avoiding thermal runaways in multi-phase high-amp circuits.
Direct-Burial Ring Stiffness (SN8-SN16)
Engineered ring stiffness grades allow direct trench burial under highway arterials and railway crossings without requiring full concrete encasement. The pipe’s high impact resistance under sub-zero handling temperatures preserves integrity against rock falls during rapid civil backfilling operations.
