The CU/XLPE/CWS/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 copper conductor). It uses copper conductors, XLPE insulation, copper wire screen (CWS), steel wire armour (SWA), and PVC outer sheath, providing strong mechanical protection for medium-voltage underground distribution systems.
Compared with tape armoured structures, SWA offers higher tensile strength, making it more suitable for long pulling distances and installations with higher mechanical stress.

SWA is chosen when the installation involves long pulling distances or higher tensile stress during laying.
Yes, slightly. It increases stiffness, so larger bending radius is required during installation.
Typically 15 × cable OD for installation and 12 × OD for fixed installation.
Up to 90°C continuous, with short-circuit up to 250°C (max 5 seconds).
Yes. SWA provides sufficient mechanical protection for direct burial with proper trench bedding.
Avoid sharp bends, control pulling force, and use rollers for long routes to prevent sheath damage.
