HVDC Products
(RC, CR, RCR, R Products)

In response to the growing demand for HVDC grid solutions, CONDIS’ proficient engineering team specialises in designing capacitors and resistor‑capacitor assemblies tailored for a wide range of DC applications. In HVDC systems, our products are primarily used in association with DC switches - typically as grading RC or pure resistive solutions - as well as in DC circuit breakers, where RC, CR or RCR configurations are implemented to ensure controlled voltage distribution and transient performance. CONDIS also supplies grading resistors and combined assemblies for laboratory and test applications. By integrating resistive and capacitive components, in series and/or parallel, within a single housing, we optimise space utilisation, reliability and overall cost‑effectiveness.

Some of the benefits we offer

Swiss‑made and backed by decades of experience in high‑voltage capacitor manufacturing, our products reflect a long tradition of engineering excellence and uncompromising quality. Designed for high performance and long, maintenance‑free service life, our capacitors rely on advanced synthetic oil‑based technologies to ensure stable operation under demanding electrical and environmental conditions. By integrating resistive elements in series and/or parallel directly within the capacitor housing, CONDIS delivers compact, safe, and highly reliable solutions for sophisticated high‑voltage applications.
