The AL/XLPE/CTS/SWA/PVC three-core power cable 8.7/15kV manufactured by Zhongdong Cable is designed in accordance with IEC 60502-2 and IEC 60228 (Class 1 or Class 2 aluminium conductor). It uses aluminium conductors, XLPE insulation, copper wire screen (CTS), steel wire armour (SWA), and PVC outer sheath, providing a cost-efficient solution for medium-voltage underground distribution systems with strong mechanical protection.
The SWA structure improves tensile strength, making the cable suitable for long pulling routes and underground installations where higher mechanical stress may occur.

It reduces cable cost and weight, making it suitable for long-distance underground distribution projects.
SWA increases tensile strength and mechanical protection, especially during pulling and direct burial installation.
Yes, aluminium has higher resistance than copper, so conductor size is usually increased to meet the same load requirement.
Typically 15 × overall cable diameter during installation and 12 × diameter for fixed installation.
Yes. SWA provides sufficient mechanical protection for direct burial in properly prepared trenches.
Avoid sharp bends, control pulling force, and use rollers for long runs to prevent sheath and armour damage.
