Even nowadays, conductors for MV cables to Swiss standards are made of braided round copper wires. The inner and outer cross-linked semiconductor is welded permanently with the XLPE insulation. For EPR insulation, on the other hand, the outer semiconductor is glued.

The screening is formed by the outer semiconductor layer, together with a layer of round copper wires. A suitable screening cross-section is assigned to each conductor cross-section. The copper wire screening is held together by a copper band, also ensuring the electrical cross-connection between the copper wires. Lengthwise water-tightness is guaranteed by embedding the copper sheath in expansion strips.

Protection against corrosion is provided by a halogen-free black outer casing with two lengthwise red stripes.

Three single conductor cables can be braided together to make a triple-conductor or triple-casing cable. If cable laying conditions are difficult, it is also possible to lap the cables with tensile and protective armouring which consists of a layer of galvanised flat steel wires.
