Polish term or phrase: wytrzymałość udarowa
Ze specyfikacji linii kablowych 110 kV:

''- napięcie znamionowe Un = 110 kV;
- najwyższe napięcie robocze sieci Un max =123 kV;
- częstotliwość znamionowa f = 50 Hz;
- udarowa wytrzymałość izolacji kabla i oprzyrządowania - 550kV;''

4.1.3 Rated insulated level
The rated insulation level is the value of the impulse withstand voltage and the value of the power frequency withstand voltage, which together characterise the insulation of the switchgear with regard to its ability to withstand the electric stresses.

cable insulation resistance

b. Cable insulation resistance shall be recorded for each phase cable, from conductor to shield, using a 5 kV (minimum) megger. Insulation resistances shall be recorded for record purposes only. - http://www.lutherforest.org/documents/LutherForestUndergroun... - page 47

------

Megohmmeter or megger is a special type of ohmmeter used to measure the electrical resistance of insulators. Insulating components, for example cable jackets, must be tested for their insulation strength at the time of commissioning and as part of maintenance of high voltage electrical equipment and installations. - https://en.wikipedia.org/wiki/Megohmmeter

---------

Insulation resistance measurements are commonly used to evaluate insulation systems.
For shielded cable, insulation resistance is directly related to the volume resistivity of the cable - http://electrical586.rssing.com/chan-5029930/all_p2.html
