1. Easy to maintain, easy for line span, its mechanical property can meet a big line span;
outer OPGW is metal armoring, with no influence for high pressure electro-corrosion and degradation;
2. To construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing high pressure line over 110kv;
Application
1. OPGW cable is mainly used in 500KV, 220KV and 110KV lines, limited by power cut, security and other elements, mostly used in new lines.
2. Its applications are: high pressure over110kv, with a longer span (usually over 250M);
1. Central Aluminium-Coated steel(ACS) Tube Single Stranded Layer
2. Central Stainsteel tube single layer design
Note:
1. Only a part of cables are listed in the table. Cables with other specifications can be inquired.
2. Cables can be supplied with a range of single mode or multimode fibers.
3. Specially designed Cable structure is available on request.
