High-voltage transmission line optical cable downlead
Downlead clamps, also known as downlead cushions, are mechanical fittings used in power transmission and communication line systems. It is best suited to applications where the ground wire will be replaced by an identical cab e due to tower limitations. Because of this, OPGW contains exposed elements made of both s ainless steel and aluminium. Curr ntly, there are a limited number of industry documents that address the requirements for optical fiber cables near high voltage circuits. Many electric utilities are installing high capacity fiber optic cables and wires on their high voltage lines to satisfy their own internal communication needs and to gain additional revenues by leasing excess capacity to telecommunication network providers.
