Cable Structure
Applications
Reconstruction of old power lines and low voltage level lines.
Coastal chemical industrial areas with heavy chemical pollution.
Main Features
● Good anti-corrosion performance.
● Material and structure are uniform, with good resistance to vibration fatigue.
● Short circuit current has small effect on the optical fiber transmission properties.
● Good anti-lightning performance.

The Advantages of GL' OPGW Optical Ground Wire
Benefits
OPGW Optical Ground Wire Cables provide all of the benefits of a traditional shield wire, such as providing short circuits a path to ground and protecting the circuits from lightning strikes, and good compactness, in addition to providing an optical pathway for communication, highly stable, high reliability, high tensile strength, high communication quality, low cost, low transmission signal loss, anti-electromagnetic interference, not easy to be stolen and cut, and not easy to be destructively attacked.
Manufacturer
Our OPGW fiber cable factory with 20 Years of industrial experience, For Now, GL 20 sets of OPGW cable equipment, Our factories can produce OPGW can reach 200KM/day, our annual capacity is about 54,750km. Our OPGW Cable is 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 the purchaser and manufacturer.
As a general rule the tests will be performed meet the international standards such as IEC60794 and IEEE1138 and can be manufactured according to customers' requirements.
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 the makerʼs certificate of a 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.
