This multi-core power cable is designed with compacted copper conductors, XLPE insulation, and a copper tape metallic screen, combined with double steel tape armour for enhanced mechanical protection.
The double steel tape armoured structure improves resistance to external impact while maintaining stable electrical performance in medium voltage power transmission systems.
An assembled core structure with PP yarn fillers and PVC sheathing contributes to overall cable stability and structural integrity.
