OPGW Optical Fiber Cable 6F 12F 24F Singlemode Multimode Hybrid Optical Ground Wire
Description
OPGW is a type of cable structure with composite of optical transmission and overhead ground wire for power transmission. It’s
working in power transmission line both as optical fiber cable and overhead ground wire which can provide protection of
lightning strike and conducting short circuit currency.
The OPGW consists of stainless steel tube optical unit, aluminum cladding steel wire, aluminum alloy wire. It has central
stainless steel tube structure and layer stranding structure.
Application
Lightness, small outer diameter, no torsion, high tensile resistance
High modular of elasticity, suitable for large stress-strain
Small thermal expansion coefficient
Good vibration resistance
Excellent flexibility capability
Free from lighting, and electric-magnetic interrupt
Adapt different span and sag installation requirements through changing sectional area of aramid fibers in the cable
Technique Paremeter

Typical Design for Single Layer
Superior Lightning Resistance
• Fewer Aluminium Alloy (AA) wires are needed to meet electrical specs
• More/Heavier duty ACS wires can be used
• AA wires can be completely replaced with ACS in some applications
Extruded Aluminium Core tube
• Good combination of crush and kink resistance
• Core tube can safely and easily be routed to closures without armour
• Easy access to optical core Superior
Electrical Performance
• Aluminium core tube substantially increases conductor cross-section
• Improved short-circuit capacity
High performance. Even in High fibre Counts
• All fibres are housed in the core tube
• Core tubes are available in a wide range of Inside Diameters
• Armour wires are not replaced with fibre tubes in high count designs
