The cable is designed to be installed on transmission and distribution lines to carry voice, data and video communications, especially in lighting waveform monitoring system, an observation system for overhead test line, maintenance data information system, power line protection system, power line operation system, and unmanned substation monitoring.
• Stainless steel tubes filled with hydrophobic gel provide the protection and support of the optical fibres
• Good tensile performance
• Small diameter, light weight, low additional load to the tower
• Appropriate fibre excess length of optical unit easliy to make
• Transport/storage temperature: -40℃ to +65℃
OPGW stands for Optical Ground Wire. OPGW cables consist of a central core formed by one or more layers of optical fibers surrounded by layers of steel or aluminum wires. The steel or aluminum wires serve the dual purpose of providing structural support as well as grounding for the power line. The optical fibers within the cable are protected by these metallic layers, shielding them from environmental factors.
