### **Power Contacts for Outdoor Isolator/Disconnector Switch (>66KV)**
#### **Technical Overview:**
Power contacts play a vital role in high-voltage isolator/disconnector switches, ensuring efficient current conduction with minimal electrical losses. Designed for voltages exceeding 66KV, these contacts are engineered to deliver superior electrical and mechanical performance, even under harsh environmental conditions. Their robust construction and advanced surface treatments help maintain low contact resistance, ensuring system reliability and longevity.
#### **Material & Surface Treatment:**
Manufactured from high-purity electrolytic-grade copper, the contacts offer excellent electrical conductivity. To enhance durability and corrosion resistance, they are available with silver or tin plating. The silver-plated variant (customizable thickness) provides excellent oxidation resistance and maintains a stable, low-resistance interface over prolonged operational cycles.
