8.7/15kV XLPE Insulated Copper Power Cable with CWS SWA PVC for Underground Installation
Product Overview
The 8.7/15kV copper conductor power cable is designed for medium voltage power distribution systems. It adopts XLPE insulation combined with copper wire screen (CWS), steel wire armour (SWA), and a PVC outer sheath to provide stable electrical performance and mechanical protection.
This cable structure is suitable for fixed installations where reliability and durability are required under medium voltage operating conditions.
Construction
- Conductor: Stranded copper conductor (Class 2)
- Conductor Screen: Semi-conductive layer
- Insulation: XLPE (cross-linked polyethylene)
- Insulation Screen: Semi-conductive layer
- Metallic Screen: Copper wire screen (CWS)
- Armour: Steel wire armour (SWA)
- Outer Sheath: PVC
Key Features
- XLPE insulation with stable electrical and thermal characteristics
- Copper conductor with low electrical resistance
- Copper wire screen for controlled electric field distribution
- Steel wire armour providing resistance to mechanical impact
- PVC sheath suitable for outdoor and underground conditions
- Designed for fixed installation in medium voltage systems
Applications
This cable is suitable for use in medium voltage distribution networks:
- Underground power distribution lines
- Substation feeder connections
- Industrial and infrastructure power systems
- Utility distribution networks
- Cable ducts and trench installations
Technical Specifications
- Rated Voltage: 8.7/15kV
- Conductor: Copper, stranded (Class 2)
- Insulation: XLPE
- Metallic Screen: Copper wire screen
- Armour: Steel wire armour
- Sheath: PVC
- Installation Method: Underground / duct / tray

Electrical & Mechanical Performance
The XLPE insulation ensures stable dielectric performance under operating conditions, while the copper conductor supports efficient current transmission. The copper wire screen contributes to electric field control and provides a path for fault currents. The steel wire armour enhances mechanical protection during installation and service.
Installation Considerations
- Suitable for direct burial with proper bedding and backfilling
- Can be installed in ducts or cable trenches
- Bending radius should comply with standard requirements
- Metallic screen should be properly earthed
Typical Use Case
In a medium voltage distribution project, this cable can be installed between substations and load centers. The armoured structure allows underground routing, while the screened design supports stable system operation.
