- Mining Operations: Surface and underground mining applications, where robust armoring withstands harsh terrain and potential damage.
- Infrastructure Projects: Tunnels, airports, water treatment plants, and transportation hubs—powering pumps, lighting, and critical systems.
- Renewable Energy: Connecting wind turbine generators, solar farm inverters, and energy storage systems to the main power grid.
- Commercial Complexes: Main distribution feeder for large buildings, hospitals, data centers, and shopping malls.
- Utility Networks: Secondary power distribution for municipal and industrial utility grids.
Why Choose Our XWA 6.6kV Medium Voltage Cable?
Selecting the right medium voltage cable is a critical decision that impacts the safety, efficiency, and longevity of your entire power network. The XWA 6.6kV medium voltage cable isn’t just a component, it’s a strategic investment in uninterrupted power.
- Superior HEPR Insulation: Our advanced HEPR insulation offers greater flexibility and superior resistance to heat and moisture than standard XLPE, ensuring your cable maintains its integrity for decades.
- Enhanced Safety Options: We offer Low Smoke Zero Halogen (LSZH) sheathing, which minimizes toxic fumes in a fire to protect personnel in tunnels, mines, and buildings.
- Precision Engineering: With over 15 years of specialized experience, we manufacture to tight tolerances that exceed IEC standards, minimizing energy loss for consistent, efficient power.
- 100% Factory Tested: We don’t rely on batch sampling; every single meter of XWA 6kV cable is rigorously tested before leaving our facility, guaranteeing reliability and eliminating on-site surprises.

FAQs of 6kV Cable
What does “XWA” stand for in XWA 6.6kV cable?
“XWA” is our trusted brand name, specializing in high-quality power cables. The XWA 6.6kV Medium Voltage Cable is a flagship product of our brand, featuring XLPE insulation and wire armoring to deliver superior performance and reliability.
Can the XWA 6.6kV cable be used for direct burial?
Yes, the wire armoring provides excellent protection against crushing and ground stresses, making it ideal for direct burial applications (compliant with local codes).
Is the XWA 6.6kV cable suitable for hazardous areas?
Suitability for hazardous areas (flammable gases/dust) depends on the complete installation, including approved glands and seals. Consult our technical team and relevant standards (IECEx, ATEX) for specific zones.
What is the difference between 6.6kV and 11kV medium voltage cables?
The primary difference is rated voltage and insulation thickness. XWA 6.6kV cable is designed for 6000-volt systems, while 11kV or 10kV cables require thicker insulation to withstand higher electrical stress. Using XWA 6.6kV cable in an 11kV system is unsafe and non-compliant.
