Special Application Capacitors

Capacitor selection for HVDC equipment, rail transit, high-frequency power supplies and industrial protection circuits, with project-specific requirements to confirm.

Special-application capacitor selection depends on the electrical, thermal, mechanical and environmental requirements of the system. Performance and applicable standards need model-specific documentation.

The catalogue covers UHVDC circuit-breaker modules, VSC-HVDC and DC-DC converters, rail traction, high-frequency power supplies and grounding protection. Grounding and snubber protection are not interchangeable functions. HAOQI coordinates confirmation of ratings, connections, cooling, dimensions and available documents for the selected application.
