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.
Fiber Type: G652D; G655C;
Fiber Count: 12-144 Core
Standard: IEEE 1138、IEC 60794-4、 IEC 60793、TIA/EIA 598 A
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 lightning.
4. To construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing a high-pressure line over 110kv.
5. Apply to the transformation of old lines.

GL FIBER' OPGW cable is mainly divided into: central-type stainless steel tube OPGW, stranded-type stainless steel tube OPGW, al-covered stainless steel tube OPGW, aluminum tube OPGW, lightning resistant central stainless steel tube OPGW with compressed wires and OPPC.
All the OPGW cable supplied from GL FIBER will be 100% tested before shipping, There are different general test series to assure the quality of OPGW cable, Such as:
Type test
Type test may be waived by submitting makerʼs certificate of the similar product performed in an internationally acknowledged independent test organization or laboratory. If type test should be performed, it will be carried out according to an extra type test procedure reached to an agreement between purchaser and manufacturer.
Routine test
The optical attenuation coefficient on all production cable lengths is measured according to IEC 60793-1-CIC (Back-scattering technique, OTDR). Standard single-mode fibers are measured at 1310nm and at 1550nm. Non-zero dispersion shifted single‒mode (NZDS) fibers are measured at 1550nm.
Factory test
Factory acceptance test is carried out on two samples per order in the presence of the customer or his representative. The requirements for quality characteristics are determined by relevant standards and agreed quality plans.
Feedback:
In order to meet the world’s highest quality standards, we continuously monitor feedback from our customers. For comments and suggestions, please, contact us, Email: [email protected].
