Cable Structure：
Fiber Type:
Fiber Type: G652D; G655C; 657A1; 50/125; 62.5/125; OM3; OM4 As Options
Applications:
Aerial, Overhead, Outdoor
Main Features:
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.

Standard:
Our OPGW cables are 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 Products supplied from GL Technology meet international standards such as IEC60794 and IEEE1138 and can be manufactured according to customers' requirements.
The advantages of GL’ OPGW Optical Ground Wire:
Technology:
GL continuously develops new OPGW products like the most comprehensive and most complete OPGW accessories.
Manufacturer:
Our OPGW factory with the 19 Years industrial experience,since 2023,our annual capacity is about 54,750km.Our OPGW Cable widely used in more than 80 countries and regions, Such as Ecuador, Chile, Peru, Philippines, Vietnam, Iraq, Poland, Thailand, Spain, Brazil,etc.
Quality:
GL support complete, advanced test support for our OPGW Cable and hardware fittings.
OPGW tests shall be in accordance with applicable standards or agreements between purchaser and manufacturer.
As a general rule the tests will be performed according IEC 60794-4-10.However, if necessary tests can be done according to IEEE Std1138.
The Optical Fibres of OPGW cables supplied in this specification meet the requirements of ITU-T G.652.D, ITU-T G.655.
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 byrelevant standards and agreed quality plans. GL has passed the tests by authoritative institutions at China Electric Power Research Institute and Shanghai Electric Cable Research Institute.
Service:
GL Provides the perfect pre-sales, sales, and post-sales service for our customers.
