III. Key Features

3.1 Double Insulation Advantage

  • Enhanced Electrical Safety: The inner XLPE layer provides excellent electrical insulation, while the outer TPE layer acts as an additional barrier, reducing the risk of short circuits and electrical leakage even if the outer layer is damaged.

  • Moisture and Chemical Resistance: The dual insulation system effectively prevents moisture ingress and resists chemical corrosion, making it suitable for outdoor and harsh environment installations.

3.2 High - Purity Copper Conductor

  • Superior Conductivity: The 99.97% oxygen - free copper conductor ensures low electrical resistance, minimizing power losses during transmission and maximizing the efficiency of solar power systems.

  • Long - Term Reliability: Copper’s excellent conductivity and corrosion resistance properties guarantee stable performance over the cable’s long service life.

3.3 Robust Construction for Harsh Environments

  • UV and Weather Resistance: The outer TPE insulation is UV - stabilized, protecting the cable from degradation caused by prolonged sunlight exposure. It can withstand extreme weather conditions, including heavy rain, strong winds, and temperature fluctuations.

  • Abrasion and Mechanical Protection: The double insulation layers offer enhanced protection against abrasion, cuts, and mechanical damage, ensuring the cable’s integrity in challenging installation scenarios.

IV. Applications

4.1 Residential Solar Systems

  • Ideal for connecting rooftop solar panels to inverters in homes, providing a safe and reliable power transmission solution. The 6 sq mm size is suitable for systems up to 10kW, ensuring efficient power flow with minimal voltage drop.

4.2 Commercial and Industrial Projects

  • Well - suited for commercial buildings, factories, and industrial complexes with medium - scale solar installations. It can handle the higher power demands of these setups while maintaining safety and performance standards.

4.3 Off - Grid and Remote Installations

  • In remote locations such as rural areas, off - shore platforms, or remote research stations, this cable’s durability and resistance to harsh conditions make it a reliable choice for power transmission in off - grid solar systems.

4.4 Temporary and Portable Solar Setups

  • For temporary solar installations, such as events, construction sites, or portable solar power kits, the cable’s flexibility and easy installation features make it a convenient option.

V. Installation and Maintenance

5.1 Installation Guidelines

  • Bending and Routing: When installing, ensure that the minimum bend radius of 24.8mm is maintained to avoid damaging the insulation layers. Use appropriate conduits or protective tubing for outdoor installations to further safeguard the cable.

  • Termination: Connect the cable to compatible 1000V DC rated connectors, such as MC4 connectors. Ensure proper crimping and sealing to prevent moisture and contaminants from entering the connection points.

5.2 Maintenance Tips

  • Regular Inspection: Periodically inspect the cable for any signs of damage, such as cuts, cracks, or discoloration. Pay special attention to the insulation layers and connection points.

  • Cleaning: In case of dirt or debris accumulation, clean the cable gently with a soft, dry cloth. Avoid using abrasive materials or chemicals that could damage the insulation.

VI. Packaging and Warranty

  • Standard Packaging: Supplied in 100 - meter rolls, wrapped in UV - protective film and placed on sturdy cardboard reels for easy handling and storage. Custom lengths are also available upon request.

  • Warranty: Backed by a 10 - year warranty, our single core double insulated solar cable ensures peace of mind. We guarantee the product’s quality, performance, and compliance with the specified standards.

This 6 sq mm, 1000 volts DC single core double insulated solar cable offers a perfect combination of safety, durability, and efficiency, making it an essential component for reliable solar power systems. Contact us today for more information, pricing, or to place an order.
