Expert Q&A: Professional Insights

Why is the material of the cable jacket critical for wholesale EVSE extension cords?
The jacket (usually TPU or TPE) must resist UV radiation, ozone, and chemical exposure (like oil or road salt). Cheap PVC jackets tend to crack in sub-zero temperatures, leading to safety hazards. Our cords are rated for -35°C to 75°C.
How does Tongxing ensure the safety of high-power DC charging?
We implement a dual-core redundancy protection system. This includes real-time insulation monitoring, surge protection, and an AI-driven thermal management system that adjusts the current if terminal temperatures exceed safety thresholds.
What is the advantage of an "Integrated Photovoltaic-Energy Storage" solution?
It solves the "grid stress" issue. By storing solar energy locally, you can provide ultra-fast charging without upgrading the local transformer, while reducing operational costs by up to 30% through peak-shaving.
What certifications should a reputable wholesale factory possess?
At a minimum, ISO 9001 for management, and CE, TÜV, UL, or CB for product safety. Tongxing holds all major international certifications, ensuring legal and safe entry into 45+ global markets.
