Material: Crafted from high - purity oxygen - free copper (purity ≥99.97%) and tinned, the conductors offer excellent electrical conductivity and enhanced corrosion resistance. The tin coating protects the copper from oxidation, ensuring stable performance even in harsh outdoor environments with high humidity and exposure to the elements.

Stranding: Stranded construction provides flexibility, allowing the cable to be easily routed around complex structures during installation, such as rooftops with multiple obstacles or through tight conduits.

Inner Insulation: Cross - linked polyethylene (XLPE) is commonly used as the inner insulation material. It provides superior electrical insulation, effectively preventing electrical leakage and short circuits. XLPE also has high thermal stability, enabling the cable to operate reliably within a wide temperature range, from - 40°C to + 90°C, and with short - term tolerance up to + 120°C.

Insulation Thickness: Carefully designed to balance insulation performance and overall cable size, the insulation thickness ensures optimal protection while facilitating installation and handling.

Material: Constructed from UV - stabilized, halogen - free thermoplastic elastomer (TPE), the outer sheath offers comprehensive protection against environmental factors. It resists long - term UV radiation, moisture, abrasion, and mild chemicals, significantly extending the cable's lifespan and ensuring reliable operation in outdoor PV installations.

Color Coding: Often color - coded for polarity identification, for example, a black outer sheath may indicate the negative conductor, while a red or brown sheath could signify the positive conductor, simplifying correct connection during installation.

Termination: Use connectors rated for 6mm² cables and the cable's voltage and current capacity. Ensure proper crimping or soldering of the connectors to create a secure electrical connection. For example, when using MC4 connectors, make sure they are fully engaged and locked to prevent loose connections that could lead to overheating.

Routing: When routing the cable, follow the minimum bend radius requirements to avoid damaging the insulation and conductors. Use cable clips, conduits, or trays to support and protect the cable, especially in areas where it may be exposed to mechanical stress, such as around sharp corners or in high - traffic zones. Keep the cable away from other electrical cables to prevent electromagnetic interference.

Polarity Check: Double - check the polarity of the cable connections before powering on the PV system. Incorrect polarity can cause damage to the equipment, reduce the system's efficiency, or even pose a safety risk.

Regular Inspection: Conduct routine visual inspections at least once a year, or more frequently in harsh environments. Look for signs of damage, such as cuts, cracks, or discoloration of the insulation, as well as any signs of wear or abrasion on the outer sheath. Check the connectors for any indications of overheating, corrosion, or looseness.

Cleaning: If dirt, dust, or debris accumulates on the cable, clean it gently using a soft, dry cloth. Avoid using abrasive materials or harsh chemicals, as they can damage the outer sheath and compromise the cable's protective properties.

Performance Monitoring: Periodically measure the insulation resistance and DC resistance of the cable to assess its performance over time. A significant decrease in insulation resistance or an increase in DC resistance may indicate internal damage or degradation, and appropriate actions, such as cable replacement, should be taken promptly.
