Steel-aluminum layer-stranded cables

EN 50182, ÖNORM E 4004, MSZ-149/4

 

They are mainly used for high-voltage transmission lines, mounted on insulators on poles. The layer-stranded cables consist of galvanized steel wire or a galvanized steel core and one or more layers of aluminum cores stranded around it. We can deliver the layer-stranded cables according to the MSZ 149/4, DIN 48204, BS 215, CSA C49 standards etc. In addition, we also manufacture all sizes and structures according to the European standards in force, in accordance with EN 50182.

The table below shows the technical parameters of the layer-stranded cables made according to MSZ 149/4 standard.
