YesYes
Symmetrical shielded (or ar-
mored) cable with three phase
conductors and symmetrically
constructed PE conductor and
a shield (or armor)
YesYes
Symmetrical shielded (or ar-
mored) cable with three phase
conductors and a shield (or ar-
mor), and separate PE conduct-
or/cable
1)
1)
A separate PE conductor is required if the conductivity of the shield (or armor) is not sufficient for the PE use.
