SANS Type 66 / 66-ECC 3.8/6.6 kV Cable Feature

Certification Standards: Widely recognized and understood in the South African market.
Lightweight and Flexible: Easier to handle and install compared to armored cables like Type 133 (SWA), particularly suitable for cable tray and conduit installations.
Cost-Effective: Eliminates the need for additional armor when the installation method itself provides mechanical protection (e.g., substation cable trays).
Corrosion Resistance: PVC sheathing exhibits minimal susceptibility to corrosion, contrasting sharply with steel wire armoring materials.
Superior Electrical Properties: Cross-linked polyethylene insulation delivers high dielectric strength and low loss characteristics.
