Cáp OPGW l 24 lõi mặt cắt ngang 85 singe mode

The central AL-covered steel tube is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires.AL-covered Stainless Steel Tube design increases the cross section of AL,to reach a better fault current and lightning resistance performance.Apply to the transmission line which requires small diameter and large fault current.
 

Characteristic:
1，High quality IEC607948 IEEE1138 standards for designing, testing and producingwith 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.
