Device of test of AB-50/70 dielectrics

The device high-voltage test AB-50/70 is developed for test of isolation of power cables and solid dielectrics by the straightened voltage, and also for test of solid dielectrics sinusoidal voltage with a frequency of 50 Hz.

• The device is calculated for operation under a canopy or in rooms at working values of air temperature from minus 10 °C to plus 40 °C, relative humidity of 80% at a temperature plus 20 °C and the atmospheric pressure of 84,0 - 106,7 kPa (630 – 800 mm Hg).

For test of cables with isolation from the sewed polyethylene at a frequency of 0,1 Hz the AB-45-0,1 SNCh-prefix is applicable to the Device AB-50/70. In more detail here...
