Ropes for overhead lines are produced by a modern technology of drawing of wires and stranding of ropes, with possibility of forming 5-layer constructions. Such a technology provides for quality and a firm connection between the layers and in that way guarantees that, during permanent functioning of the rope, layers cannot separate, maximal possible purity of all the layers can be achieved and with it, also a long durability.
ELKA’s production programme comprises manufacturing of ropes for overheads lines, based on aluminium, as well as steel-protection ropes.
Ropes for overhead lines consist of seven or more wires stranded in concentric layers. If a rope consists of several layers, neighbouring layers are stranded in opposite directions. The last layer has got the right-hand stranding direction.
