คําอธิบายสินค้า

Product Introduction

The 12/20kV Medium Voltage Single Core Aluminum Conductor XLPE Underground Power Cable is designed for reliable direct burial and underground power distribution in industrial and infrastructure EPC projects. Manufactured in compliance with IEC 60502-2, this aluminum core cable delivers superior electrical performance combined with mechanical robustness for long-term underground operation.

The stranded compacted aluminum conductor ensures excellent conductivity and flexibility, while the XLPE insulation provides high dielectric strength and thermal stability up to 90 deg C. A copper tape or wire screen layer ensures uniform electric field distribution, and the PVC/PE outer sheath guarantees moisture resistance and mechanical protection in underground environments. This medium voltage cable is widely used in:

  • Industrial EPC Projects — Turnkey power distribution for processing plants, factories, and industrial complexes
  • Infrastructure Development — Underground power backbone for metro systems, airport terminals, and urban utilities
  • Mining Power Supply — Reliable medium voltage transmission for mining operations and underground tunnels
  • Direct Burial Applications — Cable trench and duct installations requiring long-term underground durability

Engineered as a complete underground power cable solution, this product combines the cost advantages of an aluminum conductor cable with the proven reliability of XLPE insulation technology, meeting the rigorous demands of international EPC specifications.

Engineering Advantages

  • Optimized for Underground Installation: Specially designed PVC/PE outer sheath provides superior moisture resistance, soil chemical resistance, and mechanical protection for direct burial and cable trench applications with 30+ years design life.
  • High-Conductivity Aluminum Core: Stranded circular compacted aluminum conductor (Class 2 per IEC 60228) delivers excellent conductivity-to-weight ratio, reducing cable weight by approximately 50% compared to equivalent copper conductor cables — lowering installation and logistics costs for large-scale EPC projects.
  • XLPE Insulation Reliability: Cross-linked polyethylene insulation provides outstanding dielectric strength, low dielectric loss factor, and thermal stability up to 90°C, ensuring reliable MV power transmission with minimal maintenance.
  • Industrial-Grade Durability: Robust construction withstands harsh industrial environments including chemical exposure, UV radiation, mechanical stress, and wide temperature fluctuations — suitable for mining, oil & gas, and heavy industry applications.
  • EPC Project-Ready: Full compliance with IEC 60502-2 standards, complete with third-party testing reports, factory acceptance test documentation, and project-specific engineering support for international EPC specifications.
  • Flame Retardant & LSZH Options: Available with flame retardant (IEC 60332) and Low Smoke Zero Halogen sheath options for enhanced fire safety in tunnels, metro systems, and confined installations.

Frequently Asked Questions

Q: What is the advantage of aluminum conductor over copper for underground MV cables?

Aluminum conductors offer approximately 50% weight reduction compared to equivalent copper conductors, significantly lowering transportation and installation costs. For the same current carrying capacity, aluminum cables typically cost 30-50% less than copper equivalents, making them the preferred choice for large-scale infrastructure and EPC projects without compromising performance.

Q: Can this cable be used for direct burial without additional conduit?

Yes, our 12/20kV XLPE insulated cables with PVC or PE outer sheath are designed for direct burial installation. The robust sheath construction provides adequate mechanical protection and moisture resistance. For areas with high mechanical risk, armoring (STA/SWA) is recommended. Please consult our technical team for installation-specific recommendations.

Q: What is the typical delivery time for bulk EPC orders?

Standard delivery time is 15-25 working days depending on order volume and specification. For large EPC projects, we provide phased delivery schedules aligned with project milestones. Rush orders can be accommodated with priority production arrangements.

Q: Are customized constructions available beyond standard IEC specifications?

Yes, we offer fully customized cable designs including alternative conductor sizes, special screen configurations, armored variants (SWA/STA), LSZH sheaths, and region-specific standards (BS, ASTM, AS/NZS). Contact our engineering team with your project requirements for a tailored solution.

Q: What testing and documentation is provided with each shipment?

Every cable drum ships with a Factory Acceptance Test (FAT) report including conductor resistance, voltage test, and partial discharge test results per IEC 60502-2. We also provide material certificates, drum marking details, and installation guidelines. Additional third-party inspection by SGS/BV/TUV can be arranged.
