III. Key Features

3.1 Cost - Efficiency

  • Economical Conductor: Aluminium is significantly more affordable than copper, reducing the overall material cost of large - scale PV projects. For example, in a 1MW solar farm, using 100mm² aluminium cables can lower the cable investment by up to 30% compared to copper alternatives.

3.2 High - Current Capacity

  • Powerful Transmission: With a current rating of 180A, this cable is capable of handling high - power outputs, making it ideal for connecting multiple solar panel arrays in large commercial or industrial PV systems.

3.3 Lightweight Design

  • Easier Installation: Aluminium is lighter than copper, reducing the weight of the cable by approximately 60%. This feature simplifies handling, transportation, and installation, especially in projects where long cable runs are required.

3.4 Durable Insulation

  • Weather Resistance: The double - layer insulation system, consisting of XLPE and TPE, provides excellent protection against UV radiation, moisture, and extreme weather conditions. It has been tested to withstand 1500 + hours of xenon arc exposure without significant degradation.

  • Mechanical Strength: The outer TPE sheath offers enhanced abrasion and impact resistance, ensuring the cable's integrity during installation and long - term operation.

IV. Applications

4.1 Large - Scale Solar Farms

  • Ideal for Utility - Scale Projects: In large - scale solar farms spanning hundreds of acres, 100mm² single core aluminium cables are used to connect solar panel strings to central inverters and from inverters to the grid - connection points. Their high - current capacity and long - length suitability make them a preferred choice for efficient power collection and transmission.

4.2 Industrial Solar Installations

  • Powering Manufacturing Facilities: Industrial buildings with large rooftops or adjacent land for solar panel installation can benefit from these cables. They can handle the substantial power generated by extensive PV arrays, supplying electricity to power machinery, lighting, and other industrial equipment.

4.3 Ground - Mounted PV Systems

  • Rural and Remote Areas: In rural or remote locations where large - scale ground - mounted PV systems are installed to provide electricity, the cost - effectiveness and durability of 100mm² aluminium cables make them a practical solution. Their lightweight nature also eases installation in areas with limited access or challenging terrains.

V. Installation and Maintenance

5.1 Installation Guidelines

  • Termination: Use special aluminium - rated connectors and lugs to ensure proper electrical contact and prevent oxidation at the connection points. Compression crimping techniques are recommended for secure terminations.

  • Bending and Routing: When installing, maintain a minimum bend radius of 108mm to avoid damaging the insulation and conductor. Use appropriate cable trays, conduits, or supports to route the cable safely and neatly.

  • Grounding: Ensure proper grounding of the cable as per local electrical codes. This helps protect against electrical faults and ensures the safety of the PV system.

5.2 Maintenance Tips

  • Regular Inspection: Periodically check the cable for signs of damage, such as cuts, cracks, or discoloration in the insulation. Pay close attention to connection points for any signs of overheating or corrosion.

  • 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 outer sheath.

  • Lifespan Monitoring: Although the cable has a long service life of up to 25 years under normal conditions, monitor its performance over time. Replace the cable if any significant degradation or performance issues are detected.

VI. Comparison with Copper Cables

Feature
Aluminium Cable (100mm²)
Copper Cable (equivalent)
Cost per Meter
Approximately 30 - 40% lower
Higher cost due to copper price
Weight per Meter
Approximately 60% lighter
Heavier, may require more support
Current Rating
180A
Similar, but copper may have a slight edge
Electrical Resistance
Slightly higher
Lower, better conductivity
Corrosion Resistance
Requires proper anti - oxidation treatment
Naturally more corrosion - resistant
In conclusion, the single core aluminium solar cable 100mm² offers a cost - effective, high - performance solution for large - scale PV installations. Its combination of affordability, high - current capacity, and durability makes it a valuable choice for solar project developers and installers looking to optimize their projects' cost - efficiency without sacrificing reliability.
