The aluminum wires are used in column, attached to insulators, especially medium and low tensioned distributive networks. The wire structure is one or multilayered. In case of multiple layers, the outer layer is always left threaded, the other layers are right and left threaded by turns. In the case of foreign national standards the EN standard is the authoritative
