Cable of communication optical built in lightning cable is used for suspension on supports of power lines with voltage 35 kV and above.
Description:
The optical cable contains a core of modular construction consisting of a central power element made of aluminium clad steel wire or aluminium alloy wire, around which aluminium clad steel wire and/or aluminium alloy wire are twisted and one or more optical modules, which are a sealed stainless steel tube with up to 48 optical fibres stacked inside and filled along its entire length with a hydrophobic compound. The total number of optical fibres is up to 288. Overlaid on top of the core are one or more strands of aluminium clad steel wires and/or aluminium alloy wires.
