Corrosion Resistance: The tin plating provides a protective barrier against oxidation and chemical corrosion, extending the cable's lifespan in harsh environments.
Enhanced Conductivity: Tinning improves electrical conductivity at connection points by preventing the formation of resistive oxide layers.
Thermal Stability: Maintains performance under temperature fluctuations, reducing the risk of connection failures due to thermal expansion and contraction.
3.2 Robust Insulation System
Double Insulation: XLPE inner insulation for electrical safety and TPE outer sheath for mechanical protection.
UV & Weather Resistance: Withstands prolonged sunlight exposure and extreme weather conditions without degradation.
Abrasion Resistance: Durable sheath protects against physical damage during installation and operation.
3.3 Safety & Compliance
Flame Retardant: Self-extinguishing properties minimize fire risks.
Halogen-Free: Emits minimal toxic smoke in case of fire, ensuring safety in enclosed spaces.
Compliance: Meets global standards for PV applications, including UL, TÜV, and IEC certifications.
