InSky OPGW

InSky ACS Ground Wire (Aluminum-Clad Steel Ground Wire) is a standard component of high-voltage transmission lines. It can be used when fiber capacity is not needed or when additional fault current capacity is required. Aluminum-clad steel wires are highly corrosion-resistant and can be barely destroyed by heat during accidents. The technology of cladding ensures no peeling or crumbling of the aluminum.
InSky ACS Ground Wire manufactured by Incab has a proven design life of 50 years and rated breaking strength (RBS) from 6,744 up to 157,366 lb. ACS ground wires shield high-voltage conductors from lightning strikes. Aluminum-clad steel ground wires are typically used in regions with much higher lightning activity (such as the USA or Brazil), showing excellent reliability under real operating conditions. The electrical resistance of the InSky ACS ground wire is about 2 times lower, which means it is more resistant to short-circuit current. Relatively low weight of InSky ACS Ground Wire provides lower load on transmission line supports.

InSky MASS (Metallic Aerial Self-Supporting) design is similar to OPGW design with a lower cost. It can have up to 48 fibers and its maximum rated design tension can reach up to 67,433 lb. MASS is used on medium and high voltage power lines when it is not possible to use OPGW and ADSS or it is not economically feasible. This cable is not designed to transmit electricity. Relatively small size and weight allows minimizing the load on the towers, and at the same time the necessary sag requirements are met. It is possible to suspend MASS, both in the inter-phase space, and below the phase conductors, in some cases without disconnecting the overhead line. It is suitable for large spans between towers, for installation over rivers and ravines.
Approximately one third of all damage to ADSS cables, as a rule, occurs as a result of vandalism, mainly due to gunshots, while MASS is almost invulnerable to them. Consequently, for the conditions where gunshots are a high risk, the use of MASS becomes not only economically feasible, but also, when OPGW installation is impossible, becomes the only option for building fiber optic communication lines. An additional advantage of MASS can be its insensitivity to fires under the line.
