1. Pure oxygen-free copper, anti-oxidation, low resistance, protect the electricity environment
2. Strict production to ensure low wire eccentricity and prevent current from penetrating the sheath
3. The tubular filling process is adopted, which has impact resistance, strong mechanical properties, tensile resistance, and greatly improves safety
4. Strong flexibility, not easy to break
5. PVC flame-retardant material, will not burn away from the open flame, and will instantly extinguish and produce a small amount of smoke
