Optical aerial cables for power lines
Advantages
- Loose tube design
- low attenuation because fibres are free of stresses
- no change in attenuation due to different temperatures and additional loads because
of a strain margin of at least 0,5%
- no influence of vibrations or other motions because fibres are embedded in filling jelly
- Rope like design
- mechanical and electrical characteristics like usual ground wire with similar
diameter and weight
- additional loads very similar to replaced ground wire
- behaviour and flexibility very similar to usual ground wire
- no anti-torque equipment for installation necessary
- Modular design
- change of characteristics just by replacing components
- rise of fibre count by filling up the steel tube and in case of stranded version
by additional tubes possible
- Fully metal design
- no degradation of plastic materials due to UV radiation or temperature
- high overloads in case of short circuit currents possible (no melting of plastic)
