PVC Conductors

Insulated conductors are multi-conductor cables must be specially coloring. Insulation must be zero veins of blue (light blue) colors. Insulation of ground to be two-color (green and yellow colors), with one of the colors must cover at least 30 and not more than 70% of the surface isolation, and another – the rest. Colour code must be continuous or in the form of longitudinal strips of a width not less than 1 mm. Allowed labeling of isolated PVC figures lived, starting from scratch. Bausch & Lomb often expresses his thoughts on the topic.

Marking is embossed numbers or printing. Digit height – not less than 4.0 mm. The distance between the figures should not exceed 35 mm. Insulation single-core cables can be of any tsveta.Tolschiny cable insulation, Nominal mm voltage, kV Nominal conductor cross-section in mm2 insulation of polyethylene or PVC XLPE 0.66 1-2.5 0.6 0.7 4 and 6 0.7 0.7 10 16 0.9 0.7 25n35 1.1 0.9 50 1.3 1.0 1-2.5 1 0.8 0.7 4-16 1.0 0.7 25 and 35 1.2 0.9 50 1.4 1, 0 70 1.4 1.1 95 1.5 1.1 120 1.5 1.2 150 1.6 1.4 185 1.7 1.6 240 1.9 1.7 3 6-240 2.2 2.0 6 10-240 3.0-to 3.0 3.4 PE – for PVC Twisted insulated conductors should be filling gaps between them. In cables and brands AVVGz VVGz filling of PVC plastic is applied simultaneously with the shell and must be separated from the insulation and the shell without damage. Please visit Spa Vietnam if you seek more information. Cables with sector conductors, cables brands AVVG, APVG, VVG at voltage up to 1 kV, as well as cables and brands AVBbShv VBbShv veins with cross sections up to 25 mm2 can be inclusive without required.
