Central Loose Tube OPGW Cable
Product Model: OPGW-C
Application:
1. OPGW cable is mainly used in 500KV, 220KV and 110KV lines,limited by power cut, security and other elements, mostly used innew lines. Its applications are: high pressure over 110kv, with alonger span (usually over 250M);
2.Easy to maintain, easy for line span, its mechanical property canmeet a big line span;
☆.Outer OPGW is metal armoring, with no influence for high pressureelectro-corrosion and degradation;
3.To construct OPGW must cut power, resulting in greater loss, thusOPGW must be used in constructing high pressure line over110kv;
4.For OPGW performance index, the more short circuit current, themore need a good conductor to be metal armor, and reduce tensionstrength, while, if the tension strength is certain, to increaseshort circuit current capacity, the only way is to enlarge metalsection area, resulting in an increased cable Dia and weight, sothat security is a question for line pole strength.
Features and advantages:
Extruded Aluminum Core tube
• Good combination of crush and kink resistance
• Core tube can safely and easily be routed to closures withoutarmor
• Easy access to optical core
Superior Corrosion Resistance
• Meets IEEE construction guidelines for use in High Corrosionsites
Superior Electrical Performance
• Aluminum core tube substantially increases conductorcross-section
• Improved short-circuit capacity
Superior Lightning Resistance
• Fewer Aluminum Alloy (AA) wires are needed to meet electricalspecs
• More/Heavier duty ACS wires can be used
• AA wires can be completely replaced with ACS in someapplications
High performance Even in High fiber Counts
• All fibers are housed in the core tube
• Core tubes are available in a wide range of Inside Diameters
• Armor wires are not replaced with fiber tubes in high countdesigns
• Electrical and mechanical properties can be maintained.
