The CU/XLPE/CWS/STA/PVC three-core power cable 18/30kV manufactured by Zhongdong Cable is designed in accordance with IEC 60502-2 and IEC 60228 (Class 1 or Class 2 copper conductor). It combines copper conductors, XLPE insulation, copper wire screen (CWS), steel tape armour (STA), and PVC sheath, providing a stable and cost-effective solution for medium-voltage underground networks.
The three-core construction is widely used in balanced three-phase systems, while the STA layer improves resistance to mechanical stress and makes the cable suitable for direct burial and long-term underground use.

It is usually chosen when trench space is limited and installers want to avoid laying three separate single-core cables.
Yes. The cable is stiffer, so it needs careful drum handling and steady pulling during installation.
Yes, but cable route planning is important to avoid too many sharp turns or heavy pulling sections.
The bedding must be even. Uneven ground can create pressure points on the steel tape armour.
For larger sizes, a cable roller and controlled tension equipment are recommended to avoid sheath damage.
It reduces installation complexity and keeps the phase arrangement fixed, especially in compact urban cable corridors.
