Dielectric Self Supporting Aerial Cable
Figure 8 Aerial self support cables are designed medium span aerial installations, they have ultraviolet and harsh outdoor environment protection. Up to 144 fibers are there in each jelly filled plastic compound tube, which are stranded around a FRP strength member, water blocking tape and covered by a PE outer sheath. The cable core is fully dielectric so gives lightning protection. 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 support the fiber cables to withstand the tensile force for aerial installations. The PE outer sheath gives excellent environment and ultraviolet protection to the cable.
