Product Description

Application:

OPGW cable is mainly used in 500KV, 220KV and 110KV lines,
limited by power cut, security and other elements, mostly used in new lines. Its applications are: high pressure over 110kv, with a longer span (usually over 250M);
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 pressure electro-corrosion and degradation;
To construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing high pressure line over 110kv;
For OPGW performance index, the more short circuit current, the more need a good conductor to be metal armor, and reduce tension strength, while, if the tension strength is certain, to increase short circuit current capacity, the only way is to enlarge metal section area, resulting in an increased cable Dia and weight, so that 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 without armor
Easy access to optical core
Meets IEEE construction guidelines for use in High Corrosion sites
Superior Electrical Performance
Aluminum core tube substantially increases conductor cross-section
Improved short-circuit capacity
Superior Lightning Resistance
Fewer Aluminum Alloy (AA) wires are needed to meet electrical

Specification:

More/Heavier duty ACS wires can be used
AA wires can be completely replaced with ACS in some applications
High performance. Even in High fiber Counts
All fibres 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 count designs
Electrical and mechanical properties can be maintained.
