The AL/XLPE/CWS/SWA/PVC three-core power cable 26/35kV manufactured by Zhongdong Cable is designed in accordance with IEC 60502-2 and IEC 60228 (Class 1 or Class 2 aluminium conductor). It adopts aluminium conductors, XLPE insulation, copper wire screen (CWS), steel wire armour (SWA), and PVC outer sheath, providing a practical solution for high-capacity medium-voltage underground distribution systems.
The aluminium conductor helps reduce cable weight and overall project cost, while the SWA layer provides additional mechanical protection for underground installations and long cable routes.

It is mainly used in primary MV distribution systems and large industrial power networks where higher voltage levels are required.
SWA provides strong mechanical protection for underground installation, especially in areas with soil pressure or risk of external damage.
Yes, it is commonly used in compact urban grids where space saving and simplified installation are important.
Due to higher voltage and larger size, proper cable handling and controlled pulling force are critical during laying.
Yes, but route design should minimize sharp bends and reduce installation stress to maintain insulation integrity.
