Maxwell is a leading capacitor manuacturer with rst-in-class products quality and reliability, excellent electrical & mechanicalstrength, long lietime and the ability to respond to individual customer requirements.

Maxwells MV capacitors and voltage dividers are based on a dry capacitor technology. The resin moulded capacitors are basedon CDAS technology, the companys latest technological development based on capacitor windings made o metalized polypro-pylene dielectric and impregnation with gas. Within MV capacitors and voltage dividers tens o fat windings are connected inseries. For optimal perormance and longevity these elements must be as identical as possible. Key element o Maxwells propri-etary CDAS technology is the automated stacking and series connection o the fat windings through laser welded connections.Maxwell is the only supplier o MV components in the world to completely automate its winding and assembly process. Furtheradvantage o the automated process is to perorm a quality check on each individual element as it is wound, resulting in a perectprecision o the nal product.
