Cable contains from 1 to 100 pairs of copper conductive cores with a diameter of 0,70 mm. And supply conductors with cross-section 0,50; 0,75; 1,5; 2,5 mm2. Conducting cores insulated with polyethylene of different colours are twisted in pairs.
Colour coding is used to identify pairs. Pairs are twisted in bundles and/or in a core. The bundles are colour coded, in the form of ribbons or strands of different colours, to identify the bundles.
The twisted core and supply cores are covered with a hermetic sheath made of polyvinylchloride plasticate, which does not spread combustion in group laying, with reduced smoke and gas emission and low toxicity of combustion products.
