48 Core Aluminium Armored Fiber Optic Cable OPGW Overhead Ground Wire
Overhead Power Ground Wire Aluminium Armored Fiber Optic Cable Opgw Cables 12 Core 24 Core 48core
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.
Features and Benefits
Stranded Stainless Steel Tube
- Wire strands are replaced with fiber-filled stainless steel tubes
- Fiber tubes are helically stranded alongside the wires
- Fiber strain margin is increased relative to core tube designs
- Loaded sag can be increased without inducing fiber strain
Compact Design
- Reduced weight - Increased flexibility
- Smaller minimum bend radius
- Easier to handle and install
- Lower wind and ice loads put less load on structures
Product 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
