High-Current Series
This static contact is widely used in KYN28 (GZS1) and other withdrawable switchgear as the fixed interface for the circuit breaker compartment. With a rated current of 2000A and a 79mm diameter, it is ideally suited for high-capacity distribution networks, main power transformers, heavy industrial applications, and critical infrastructure requiring robust power handling capabilities.
Surface: Silver-plated (Ag) for optimal contact reliability.
Applications: Widely used in Vacuum Circuit Breakers (VCBs), GIS, and medium-to-high voltage switchgears.
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.
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.
Silver-Plated Finish
Manufactured with a mature silver-plating electroplating process to prevent oxidation, reduce contact resistance, and ensure consistent product quality (Optional/Standard).
Robust Design
Engineered to withstand high levels of short-circuit current and thermal stress without deformation or breakdown.
Secure Fit
Dimensional accuracy of 79mm diameter with a length of 107mm ensures secure installation and consistent alignment with the moving contact.
This static contact is widely used in KYN28 (GZS1) and other withdrawable switchgear as the fixed interface for the circuit breaker compartment. With a rated current of 1600A and a 55mm diameter, it is ideally suited for medium-to-large capacity distribution networks, step-up substations, and industrial applications requiring higher power handling capabilities.
