Aluminum layer-stranded cables
EN 6889, MSZ 149/2
Aluminum layer-stranded cables are used on poles, fixed to insulators, especially in medium and low voltage distribution networks. The ropes have single or multilayer structure. In case of several layers, the outer layer is always left-stranded, other layers alternately left- and right-stranded. In the case of foreign standards, the relevant national or EN standard is applied.
The technical specifications for aluminum layer-stranded cables are in the table below.
