Utilizes high-strength tempered glass with enhanced thermal and mechanical resistance. Its smooth, hydrophobic surface minimizes dirt adhesion and excels in anti-pollution performance. Includes a "Zero-value self-explosion" feature for easy fault detection.
Caps and feet are made from hot-dip galvanized steel or aluminum for superior corrosion resistance, bonded securely via cement adhesive. Standardized locking pins ensure reliable string connections.
Inclined design promotes rainwater runoff and natural cleaning. Optimized multi-layered spacing increases creepage distance, prevents rainwater bridging, and minimizes corona discharge or partial discharge risks.
