High-Current Series
This static contact is specifically designed for high-current withdrawable switchgear (such as KYN28-12/4000A, KYN61-40.5, or generator outlet panels) as the fixed interface for the circuit breaker compartment. With a rated current of 4000A and a 109mm diameter, it is ideally suited for:
Main incoming feeders in large-scale industrial plants
Generator outlets and power station auxiliaries
Electric arc furnace transformer circuits
Hyperscale data centers and critical power infrastructure
Heavy mining and marine applications
Surface: Silver-plated (Ag) for optimal contact reliability.
Applications: Widely used in Vacuum Circuit Breakers (VCBs), GIS, and medium-to-high voltage switchgears.
This contact ensures maximum power handling capacity, minimal temperature rise, and uncompromised reliability for the most demanding electrical environments.
The Fixed Contact (Static Contact) is a critical stationary component within high-voltage switchgear, designed to interface seamlessly with the moving contacts (such as tulip contacts) of a vacuum circuit breaker. Machined from high-purity T2 copper, this contact ensures optimal current transfer with minimal resistive losses, even under extreme continuous current conditions.
Designed for durability in fixed installations, it provides a stable termination point for busbar or cable connections. As a non-moving part, it offers inherent reliability and resistance to mechanical wear, ensuring long-term structural integrity within the contact box.
High Conductivity Material
Precision-machined from solid T2 copper, offering superior electrical and thermal conductivity compared to standard alloys.
Heavy-Duty Silver-Plated Finish
Manufactured with an enhanced silver-plating electroplating process featuring increased plating thickness (typically >12μm) to prevent oxidation, significantly reduce contact resistance, and ensure consistent product quality under extreme thermal stress.
Robust Design
Engineered to withstand extreme levels of short-circuit current and continuous thermal stress without deformation or breakdown.
Secure Fit
Dimensional accuracy of 109mm diameter with a length of 107mm ensures secure installation and consistent alignment with the moving contact.
