OPGW Cable
Overhead power ground wires, or OPGW cables, are used in 500KV, 220KV and 110KV lines with a pressure over 110KV and for longer distances, usually over 250m. The outer OPGW is made of metal armor which resists electro-corrosion. These aerial power cables work well with short circuit currents and metal armor conductors to reduce tension strength.
Features
1. Extruded Aluminium Core Tube: resistant to bending and kinks, core tube can safely be routed to closures without armour, easy access to optical core
2. Corrosion Resistance: meets IEEE construction guidelines for use in high corrosion sites
3. Superior Electrical Performance: aluminium core tube increases conductor cross-section and improves short-circuit capacity
4. Excellent Lightning Resistance: fewer aluminum alloy wires are needed and in some cases can be completely replaced wtih ACS wires.
5. High Performing Cables: all fibers are housed in core tubes available in a wide range of inside diameters
