MV Capacitors & Dividers
High Voltage Capacitors

MV capacitors are medium voltage capacitors. MV capacitors and voltage dividers are based on a dry capacitor technology. The resin moulded capacitors are based on the latest technological developments based on capacitor windings made of metalized polypropylene dielectric and impregnation with gas.

MV stands for “medium voltage”. They are used in partial discharge measurement. They are typically installed in industrial electrical networks.
