In our cable abbreviation, we have prepared a summary of codes describing how the designation of cables sold by the metre is correctly made up. For our pre-fabricated lines, we only use harmonised cables complying with the CENELEC harmonisation documents HD 21 and HD 22.
In order to allocate and use the cables correctly depending on their intended application, there are the national standards marking and the international harmonised marking for "insulated cables". The designation specifies to which loads the cables can be exposed.
