|Note 1. Marking:
z – between strand filling;
ng – not spreading of burning, including in the case of laying in beams;
LS – low smoke – and gas formation during burning and smoldering.
Note 2. Multicore cables shall have all strands of the same cross-section.
Four-core cables can have one core of smaller cross-section (zero or ground).
Five-core cables may have two cores of smaller cross-section (zero and ground).
