Abstract

The importance of optical fibre aerial cables for the communication networks of power utilities is rapidly increasing since several years. At one hand their advantages for transmission of information are well-known. On the other hand their mechanical properties make them well suited for installation in overhead lines: They are light weight, they can be attached to the conductor and they can easily be installed in existing towers. From the point of view of the fitting-manufacturer there is little difference between metallic armoured optical cables and conventional selfsupporting aerial cables. However, the optical fibre's sensitivity to radial stresses must be taken into account. For non-metallic optical cables special criteria, for example the creep of the cable sheath must be considered. The following explanations give a survey on the state-of-the-art fittings for optical fibre aerial cables.
