Optical ground wire (opgw): meaning
A type of electric wire used in overhead power lines is called an optical ground wire. Such a type of electrical cable combines communication and grounding capabilities. One or more optical fibers are contained in a tubular structure called an OPGW cable, which is covered in layers of steel and aluminum wire.
OPGW: purpose
In addition to the standard overhead ground wire, which shields the transmission electrical cables from lightning strikes and ensures current flow in the event of cable faults, optical ground wire, or OPGW, also incorporates communication functions made possible by the integrated optical fibers.
Is OPGW multimode or single mode?
Single-mode fibers are used in the OPGW.
Where is OPGW employed?
The electric utility business is the main user of OPGW. It is installed in the safe uppermost position of the transmission line where it "shields" the vital conductors from lightning while offering a telecommunications path for both internal and external communications.
What are the top 5 advantages of OPGW cable?
The high-quality signal transmission, anti-electromagnetic interference, and other features of OPGW-type power optical cable are inseparable from its widespread use in transmission networks of different voltage levels.
● It benefits from little transmission signal loss and excellent communication.
● Due to its anti-electromagnetic interference properties, it can be placed on the top of a transmission line tower without taking the best frame into account. Problems with electromagnetic corrosion and installation hanging position.
● In relation to transmission lines of different voltage levels, the operating life is longer.
● Because it is connected to the ground wire in the power network, there is no need to repeatedly build and maintain it, saving a lot of money.
● Good security, difficult to steal from and cut, and difficult to be assaulted destructively.
Types of Opgw:
Eci-wires company is the most popular company having four main types of Opgw cable:
OPGW FIBER OPTICAL PROTECTION CONDUCTOR CONDUCTORS
A type of conductor used in electrical transmission lines called an OPGW (optical ground wire) serves as a protective conductor and shields phase cables from lightning strikes. This conductor combines communication and grounding capabilities. The 95 mm² OPGW conductor is an aluminum-clad and aluminum alloy wire-encased steel tube with optical fibers within. In order to prevent the fiber optics from being harmed during the assembly and use phases, the stainless steel tube is filled with thixotropic gel.

OPTICAL FIBER STAINLESS STEEL TUBE CONDUCTORS
Eci provides a range of tube sizes and fiber counts for a number of applications as the creator and owner of the technology for inserting optical fibers into stainless steel tubes. To prevent the trapped fibers from deteriorating due to the environment, each tube is hermetically sealed and filled with a thixotropic filler material. This item is also known as FIST (Fiber in Steel Tube) or FIMT (Fiber in Metal Tube).

ACS ALUMINUM-COVERED STEEL WIRE CONDUCTORS
A high-conductivity aluminum coating is applied to the center steel wire to create aluminum-clad steel (ACS). The steel core is consistently and flawlessly covered with an aluminum coating. During transfer and twisting, the coating retains its stickiness.
