Abstract: The invention relates to a cable with a sheath and an indication material that in case of damaging of the sheath at least partially escapes from the cable.
Abstract: The invention relates to a power supply cord with at least two conductors N, L for transferring a supply voltage with two protective earths insulated from one another, which at the first end are conductively connected with each other and at the second end there is a measurement device provided for measurement of the resistance of a measuring circuit comprising the PE and measurement conductor P, and wherein in case of exceeding the resistance, a warning signal is output.
