OPGW Typical Designs of Central Stainless Steel Loose Tube

OPGW Mainly used for power communication with accessories,relay protection,automatic transmission,installation together with high-voltage lines.

The central stainless steel tube is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires. are the most widely used cables ,their design is fully adapted to the most common electric line needs.

Product Name: Optical Fiber Composite Overhead Ground Wire

Brand Place of Origin: GL Hunan,China (Mainland)

Application: Aerial , Overhead , Outdoor

Typical Design: Central Stainless Steel Loose Tube



Package & Tansportation

Application: Aerial , Overhead , Outdoor


1,High quality IEC607948 IEEE1138 standards for designing, testing and producing with grade A materials available to ensure long-term reliability .
2,Engineering support supervising and providing its own line of accessories hardware .
3,Seal stainless steel tube superior protection to the fiber optical  to moisture and extreme environmental conditions such as lightening
4,To construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing high pressure line over 110kv;
5,Apply to the transformation of old lines.

Advantages of GL OPGW fiber optic cable:

1,Three typical designs: central tube,stranded wire,PBT loose tube;
2,200km OPGW cable regular production time about 20 days;
3,Type test including salt corrosion,suitable in harsh corrosive environment,especially near the sea.

OPGW has two fiber type : one is single mode G652D , and the other is G655 , sometimes they mixed together , such like OPGW-36B1+12B4-93 [78.8;53.9] . Fiber optic cable OPGW, usually 12~48 fibers,GL can max produced 96 fibers OPGW fiber optic cable, jelly filled and fiber contained central PBT loose/aluminum cladding steel/aluminum tube, outer with AA/ACS wires armored, detailed specification on your request.
