For organisation of fibre-optic communication lines on overhead power lines with voltage 35 kV and higher; For distributed temperature and acoustic monitoring systems (DTS, DAS) of cases of dangerous activity in the area of power lines, lightning strikes, short circuits.
The cable contains a central element - a steel wire clad with aluminium, around which a web of reinforcing wires and a steel optical module with freely laid fibres is twisted. The optical fibres in the module are grouped into bundles.
Each fibre bundle is wrapped with coloured synthetic thread. The free space in the optical module is filled with hydrophobic gel.
A single bundle of reinforcing wires is spirally applied on top.
Aluminium-clad steel wire eliminates corrosion and increases thermal resistance; Protection of power lines from lightning overvoltages; Element of distributed monitoring system.
