OPGW Typical Designs of Central AL-covered Stainless Steel Tube

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

OPGW description:

1.OPGW cable is the short form of Optical Fiber Composite Overhead Ground Wire. 2.OPGW cable is suit for installation on new power lines with double function of ground wire and communication, especially for installation on normal voltage and extra high voltage power lines. OPGW can replace conventional ground wire of old power lines with increasing fiber communications function. 3. OPGW cables conduct short circuit current and provide lighting resistance. 4. OPGW cables are usually two structures. The central tube OPGW cable can obtain maximum optical fiber excess length in a smallest steel tube. The diameter of stainless steel tube is bigger than that of ACSR wire and aluminum alloy wire. The stainless steel tube is placed in the center of the stranded structure of the OPGW cable. Stranded OPGW cable can obtain secondary excess length; the diameter of stainless steel tube is consistent with diameter of aluminum alloy wire.

    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.
