Features
1. The Conductor Is Tinned Copper Conductor
① Prevents oxidation and blackening of copper wires in high-temperature, humid conditions.
② Enhances reliability and weldability for conductor terminal connections.
2. The Conductor Is Soft Copper Conductor
① Thinner single wires improve bending performance for the same load surface.
② Flexible design ensures smooth movement with solar panel sun-tracking.
③ Simplifies installation.
3. The Insulation and Sheath Are Made of Low-smoke Halogen-free Flame-retardant Material with a Temperature Resistance of 125℃
① Withstands high temperatures effectively.
② Flame-retardant insulation ensures safety.
4. Insulation and Sheath Materials Have Very Good Heat Shrinkage Function
① Superior heat shrinkage maintains solar cable safety.
5. The Insulation and Sheath Materials Are Resistant to Low Temperatures
① Performs reliably in extreme conditions, from -40℃ to 125℃.
② Resists cracking in cold environments.
6. The Cable Has Excellent Acid and Alkali Water Resistance
① Resists oxidation when exposed to water, ensuring stable welding.
② Long-term immersion in acidic or alkaline solutions is no issue.
7. Excellent UV Resistance
① Lasts up to 25 years outdoors.
② Break elongation remains below 50%.
