XLPE, PVC or EPR insulated power cables with copper or aluminium conductors according to IEC 60502 are
in general suitable for fixed installation : - indoors, outdoors, or underground
Type designation :
The type of designation is a combination of abbreviations for the main constructional elements.
The abbreviations describe the cable design from inside (conductor) to outside (outer sheath).
