In capacitors designation the first number after type is rated voltage in kV, second – rated capacitance in nanofarad.
DMR – new designation of earlier produced capacitors DMRU. DMKP and DMKF – capacitors in reinforced polymer or porcelain insulator.
Capacitive voltage dividers is designed to complete capacitive voltage transformers of voltage classes 110, 220, 330, 500, 750 kV and to secure high-frequency communication from 24 up 1000 kHz along AC electricity transmission lines of frequency 50 Hz.

As per approved
technical requirements
|
1) - Depending on the performance of the tires, there may be differences in the overall and mounting dimensions of the dividers. The required dimensions are specified when ordering.
DOCI - voltage divider for power take-off, for communication, for measuring devices.
DЕО - voltage divider capacitive for optical transformers.
