Construction

Conductor
Solid/stranded, circular annealed, bare/tinned copper wire of 1.5 sq. mm, 2.5 sq. mm, 4.0 sq. mm.
Insulation
PVC. Fully color coded cores. Core identification by printed numerals/letters also available on request. However, technically, they are not primaries. The three primary colors of pigments are magenta, yellow, and cyan. (Thus when calling "red, yellow, and blue" the primary colors of pigment, "red" is an inaccurate way of saying "magenta" and "blue" is an inaccurate way of saying "cyan"). Blue and green are secondary pigments, but are primary colors of light, along with red.
Screen
Screening by copper braid or aluminium mylar tape or aluminium wire for reinforced armour types.
Drain Wire
Drain wire of solid/stranded, bare/tinned copper wire normally provided.
Mechanical Protection
Galvanized steel wire or strip or double helical steel tape armour.
Inner and Outer Sheath
PVC Black/Grey
