Detailed Construction
- Conductor: Class 2 Aluminum Alloy, offering superior creep resistance and lightweight benefits.
- Shielding: Semi-conductive conductor and insulation shields, applied via triple-co-extrusion for a seamless interface.
- Insulation: XLPE (90°C rated), providing high thermal stability and robust short-circuit capacity.
- Testing: Each drum undergoes a 42kV/5min AC voltage withstand test to ensure Partial Discharge levels meet strict safety margins.
Huayu Cable Advantages
- Weight Reduction: Aluminum alloy is 50% lighter than copper for the same ampacity, drastically cutting installation labor and support structure costs.
- Triple-Layer Co-extrusion: The shield and insulation layers are extruded in a single pass, eliminating internal air voids that cause electrical breakdown.
- Marine-Grade Certification: DNV and ABS approvals mean our factory audits exceed standard industrial requirements for mission-critical reliability.
- Full Customization: The spec table is for reference only; we manufacture all sizes from 35mm² up to 630mm² based on your project's BOQ.
- Strict Quality Control: A mandatory 42kV high-voltage test ensures zero-failure performance in heavy-duty 24/7 industrial environments.
- Expert Export Support: Specialized in Middle East and SE Asia markets, providing complete technical consultations and one-stop compliance documentation.

FAQs
1.How do you ensure the connection safety of aluminum alloy cables?
We recommend using specialized bimetallic shear-bolt lugs. Our alloy formulation provides excellent creep resistance, preventing terminals from loosening or overheating.
2.Why is the minimum bending radius higher for this cable?
Due to the precise MV internal layers, maintaining a radius of ≥20D prevents micro-cracks in the insulation shield during high-stress installation.
3.Are core configurations other than those in the table available?
Yes. As a direct manufacturer, we customize cross-sections, core counts, and jacket materials to match your specific engineering blueprints.
