The AL/XLPE/CTS/PVC three-core power cable 8.7/15kV from Zhongdong Cable is produced in line with IEC 60502-2 and IEC 60228 (Class 1 or Class 2 aluminium conductor). It uses an aluminium conductor, XLPE insulation, copper tape screening, and PVC sheath, providing a cost-effective solution for medium-voltage distribution.
Compared with copper cables, it is lighter and more economical, making it suitable for long runs and large infrastructure projects where installation efficiency and budget matter.
The three-core unarmoured design is used in three-phase systems and is typically installed in ducts, trenches, or conduits with external protection.

Conductor: Stranded or solid aluminium conductor (Class 1 or 2)
Conductor Screen: Semi-conductive layer for electric field uniformity
Insulation: XLPE with high thermal and dielectric performance
Insulation Screen: Semi-conductive layer for controlled stress distribution
Individual Metallic Screen: Copper tape screen (CTS) on each core
Fillers / Bedding: Non-hygroscopic fillers for stable cable geometry
Outer Sheath: PVC (ST2), resistant to moisture and general environmental stress
Design: Three-core, unarmoured medium voltage cable (8.7/15 kV)
The AL/XLPE/CTS/PVC 8.7/15kV three-core cable is primarily selected for medium-voltage projects where cost optimization, reduced cable weight, and ease of installation are key priorities. The aluminium conductor allows longer drum lengths and easier handling on site, making it suitable for projects with extensive cable routing.
Typical applications include:
Large-scale utility distribution expansion projects
Solar photovoltaic power plants and wind farm collector systems
Rural electrification and regional grid upgrading projects
Industrial park power distribution networks with long feeder lines
Infrastructure projects with long cable routing distances (roads, tunnels, corridors)
Temporary or fast-deployment power supply systems for construction sites
Medium-voltage feeder systems where budget efficiency is critical

Aluminium reduces material cost and cable weight, making it more suitable for large-scale or long-distance medium-voltage projects where budget and handling efficiency are important factors.
The cable is fully designed to IEC standards. While aluminium has higher resistance than copper, it performs reliably within its rated load and is widely used in utility and renewable energy networks.
Its lighter weight allows longer cable drum lengths and easier pulling over long distances, reducing installation time and mechanical stress during laying.
Yes. It is commonly used in solar and wind farm collector systems where cost efficiency and long cable runs are key design requirements.
Designers should consider current carrying capacity, voltage drop, and installation conditions. Proper sizing ensures the aluminium conductor meets system performance requirements while maintaining cost advantages.
