Aerial Cable

Figure 8 Aerial self support cables are designed medium span aerial installations; they have ultraviolet and harsh external environment protection. Up to 12 fibres are there in each jelly filled plastic compound tube, which are stranded around a steel wire strength member, water blocking tape, corrugated steel tape and covered by a PE outer sheath. The upper part of figure 8 has seven number messenger wires made of stranded galvanized steel wire with PE outer sheath. They have small diameter, light weight, good bend resistance performance. The messenger cables, the steel wire strength member and corrugated steel tape armour gives excellent support to the fibre cables to withstand the tensile force for long haul aerial installations. The PE outer sheath gives excellent environment and ultraviolet  protection to the cable.
