The core - is round, made of soft copper wire. The veins are laid in parallel. With a cross-section of 16 mm2, a multi-wire connection is performed
Insulation - insulating PVC plastic material
The core - is made of a single insulated core or twisted from 2, 3, 4 or 5 cores. For the three -, four - and five-core cables running all cores of one section or one neutral conductor lower section, and the main conductor cross-section up to 16 mm2 — with the zero or grounding-residential
Shell - light-and heat-resistant PVC plastic
Назначение transmission and distribution of electrical energy in stationary installations with a nominal AC voltage of 0.66 or 1.0 kV with a frequency of 50 Hz.
