Custom 15kV Copper Power Cable with Heavy Copper Wire Screen for Utility Projects
Created on 08.07
At Ninglan Cable, many customers require more than standard cable specifications. Recently, we completed the production of a customized 15kV copper power cable featuring a heavy copper wire screen to meet specific project requirements for enhanced electrical shielding and fault current performance.
Unlike standard medium-voltage cables, this customized design increases the copper wire screen cross-sectional area to provide improved electrical safety, mechanical reliability, and long-term operational stability.
Why Was a Heavy Copper Wire Screen Required?
Different utility projects have different technical specifications.
For this project, the customer requested:
- Higher earth fault current capacity
- Improved electromagnetic shielding
- Better electrical field distribution
- Compliance with project technical specifications
- Long service life under demanding operating conditions
Instead of using a conventional copper wire screen, the cable was manufactured with a larger cross-sectional copper wire screen, ensuring greater current-carrying capability during fault conditions.
Cable Construction
The cable construction includes:
- Copper conductor
- Conductor screen
- XLPE insulation
- Insulation screen
- Heavy copper wire screen
- Water blocking tape (if applicable)
- PVC outer sheath
Every layer is manufactured under strict process control to ensure concentricity and electrical performance.
Manufacturing Highlights at Ninglan Cable
During production, our engineering team carefully controlled:
Copper conductor compacting
Ensures lower conductor resistance and improved conductivity.
XLPE insulation extrusion
Uniform insulation thickness is maintained throughout the production process.
Heavy copper wire screening
Compared with standard designs, the customized copper wire screen contains a larger amount of copper wires, providing:
- Higher fault current capacity
- Better shielding performance
- Enhanced mechanical stability
Finished cable testing
Before delivery, each cable undergoes comprehensive inspections including:
- Conductor resistance test
- Partial discharge inspection
- High voltage withstand test
- Insulation resistance test
- Dimensional inspection
Only qualified products are released for shipment.
