1. The shell is designed with a tubular heat sink structure, utilizing the chimney effect to achieve high-efficiency heat dissipation. 2. High current-carrying capacity. 3. Low temperature rise. 4. Low impedance and minimal resonance. 5. Compact size. 6. Protection rating IP66, waterproof and dustproof. 7. The shell surface is treated with a highly corrosion-resistant VCI coating, featuring a metallic texture and optimal decorative effect. 8. Adopting the method advocated by the International Electrotechnical Commission (IEC), where the entire shell serves as the protective earth conductor (PE), it balances electromagnetic induction between phase and earth under fault current, achieving minimal reactance. The PE conductor cross-section exceeds international and national standard requirements, with electrical and safety performance superior to busways with separately installed PE bars.
