Multi-point contact: Composed of multiple precision-stamped T2 copper contact fingers (e.g., 12 for 630A, 30 for 1250A), forming multi-point contact and effectively increasing the contact area.

Elastic pressure: A non-magnetic stainless steel bracket and a ring spring evenly apply pressure to each contact finger, ensuring reliable contact.

Surface treatment: The contact surface is thickly silver-plated and treated to prevent discoloration, preventing long-term oxidation and ensuring stable contact resistance.

Conductivity: Each contact finger forms a line contact with a circular conductor, providing self-cleaning properties and resulting in low and stable contact resistance.

Low contact resistance: Multi-point parallel contact reduces contact resistance by 30%-50%.

High stability: Uniform pressure, strong self-adaptability, minimal oxide film formation, and low resistance fluctuation.

Good heat dissipation: Gaps between contact fingers form natural heat dissipation channels, resulting in low temperature rise.

Strong short-circuit withstand capability: Uniform current distribution effectively suppresses contact bounce and can withstand large short-circuit currents.

Self-cleaning effect: Slight bounce during contact can remove the oxide layer, maintaining good contact.

It is widely used in 10kV-500kV high-voltage switchgear, including ZN63 (VS1) handcart circuit breakers, disconnecting switches, and SF6 load switches. These devices are core components of power transmission and distribution systems, making the contacts essential for ensuring stable power supply in industrial plants, power grids, and key infrastructure.
