The AL/XLPE/CWS/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 aluminium conductor). It adopts an aluminium conductor, XLPE insulation, copper wire screen (CWS), and a PVC outer sheath, providing a cost-effective solution for high-voltage medium distribution networks.
The copper wire screen enhances fault current capacity and grounding performance, making the cable suitable for higher voltage stress conditions and stable long-term operation in demanding power systems.
The unarmoured structure is suitable for installation in ducts, trenches, and conduits with external mechanical protection.

The 18/30kV aluminium conductor three-core cable with CWS screen is designed for higher medium-voltage distribution systems where stronger electrical stress control and fault current handling are required. It is commonly used in backbone power networks and heavy-duty industrial grids.
Typical applications include:
High-voltage primary distribution substations
Utility transmission and regional grid backbone systems
Large industrial plants with high load demand
Mining and metallurgical power distribution systems
Renewable energy step-up substations (wind/solar)
Urban infrastructure requiring high-capacity feeders
Underground MV trunk cable networks

Copper wire screen provides better fault current carrying capability and mechanical robustness, making it suitable for higher voltage levels and demanding power systems.
18/30kV cables are designed for higher system voltage levels and are typically used in backbone distribution and high-capacity transmission networks.
Yes. It is commonly used in underground trunk lines where stable electrical performance and strong grounding are required.
No. When properly designed to IEC standards, aluminium conductors perform reliably even in high-voltage MV systems.
Proper grounding of the CWS ensures safe fault current discharge and maintains stable electric field distribution during operation.
