OPGW (Optical Fiber overhead Ground wire)


Description:
Optical fiber is added to the features of overhead power transmission lines. It protects power transmission lines from lightening and failed current when power transmission lines fail, allowing the addition of communication features to OPGW. OPGW is currently used for many aerial lines.
Characteristics
OPGW is categorized as loose buffer-type OPGW made by containing optical fibers in a plastic tube and SSLT-type OPGW made by containing optical fiber in a stainless steel tube, depending on the structure of the optical fiber unit that wraps the optical fiber.
OPGW features:
1-Laser welded stainless steel tubes provide mechanical and thermal protection for optical fibers.
2-Light weight and small diameter
3-Good resistance to moisture and hydrogen ingress
4-Fiber counts up to 96fibers
OPGW standard compliance
