Optical Fiber Composite Overhead Ground Wires OPGW-36B1-105 ITU-T G.652 Fibers
Optical fibre composite overhead ground wire (OPGW) is an overhead ground wire containing optical fibre. It has multiple functions such as overhead ground wire and optical communication. It is mainly used for communication lines of 110KV, 220KV, 500KV, 750KV and new overhead high-voltage transmission system. It can also be used to replace the existing ground lines of the old overhead high voltage transmission system, add the optical communication line, transmit short time current and provide anti lightning protection. Other structures can be customized on request.
Characteristics
• 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
