In case of cable testing there is no PD test. although cable at the time of manufacturing or
after manufacturing passing in test of voltage grade like a cable nominally use on 220V ang it,s permissible voltage grade may be 600 V. it means this cable cannot use over to 600voltage.

In DC while we mention the voltage we are using -48V but in case of AC we mention only 230V not -230V, why we using -48V not 48V
