The optical power ground wire (OPGW), also known as the optical ground wire, is a type of cable or wire that is used in transmission line construction and contains the optical fiber unit for communication.
It has two functions, one is as a lightning protection wire for transmission lines, providing shielding protection for the transmission wire against lightning strikes and discharges.
Video, data, and various control signals form a multichannel broadband communication network. OPGW cables generally have a skeleton type, central tube type, and layer twist type.
OPGW optical cables are mainly used on lines with voltage levels of 100kv, 220kv, and 500kv. Affected by factors such as line power outages, safety, etc., they are mostly used in newly-built lines.
For Veri Cable, it always starts with a quality product. Since the first use of fiber optics, Veri Cable has led the way in innovative cable products, like overhead cable, voltage cable, solar cable, rubber cable, and fiber cable, providing our customers with superior solutions. Our robust product line is now available in more than 150 countries around the world. But quality cable products are only part of the story.
With Veri Cable, you are hiring a team of experienced engineers who carefully analyze each customer’s application and then customize the product to best suit those needs. Our resources are available for on-site training and installation supervision to ensure your cables operate reliably for years to come.
OPGW Fiber Wire
OPGW fiber operates between high-voltage transmission towers and optical fibers within the cables are used to transmit data for protection, control, and/or voice communications.
As a global leader in OPGW optical fiber cable capacity and product diversity. Veri Cable has supplied more than 200,000 km worldwide. Veri Cable also manufactures a complete range of accessory hardware for installing optical ground wire.
OPGW Cable Types
Aluminum Tube Layer Warping Core Type OPGW
Our optical fiber is located in a PBT plastic loose tube, and the outside is covered with a seamless aluminum tube. The aluminum tube is stranded with 1 to 2 layers of monofilament, which can be all-aluminum-clad steel wire or a mixed twist of aluminum-clad steel wire and aluminum alloy wire.
Aluminum Tube Center Tube Type OPGW
This fiber optic product is housed in a PBT plastic loose sleeve over a seamless aluminum tube.
The aluminum tube is stranded with 1 or 2 layers of monofilaments, which can be all aluminum-clad steel wire or a mixture of aluminum-clad steel wire and aluminum alloy wire.
Aluminum Clad Steel Tube Structure OPGW
The optical fiber is placed in a sealed stainless-steel tube, and the outer layer is covered with an aluminum layer to form an optical fiber unit. The aluminum-clad stainless-steel pipe is stranded with 1 to 2 layers of monofilament.
Rust Steel Tube Structure OPGW – Layer Stranded
The stainless-steel tube is twisted with 2 to 3 layers of aluminum-clad steel wire, or the aluminum-clad steel wire and aluminum alloy wire are twisted together, which can accommodate single or multiple optical units.
Stainless Steel Tube Structure OPGW – Center Type
The center stainless-steel tube is twisted with 1 to 2 layers of monofilament, which can be all-aluminum-clad steel wire or a mixed-stranded aluminum-clad steel wire and aluminum alloy wire.
OPGW cable can be installed as an overhead ground wire on the ground wire hanging point of any span power tower directly.
OPGW optical cable can be directly installed as an overhead ground wire on the ground wire hanging point of any span power tower. The specially designed OPGW optical cable can directly replace the overhead ground wire of the original high-voltage line without replacing the original tower head.
The construction of the optical wire communication system with the high-voltage line can save the construction cost of the optical cable and reduce the cost of the communication project. The cable diameter is small, and the weight is light, will not bring a large additional load to the tower, with operating temperature -40 —70 ℃
- Outer Layer Stranding Direction: Right
- External Diameter: 10.20 mm
Storage Temperature:-40 —70 ℃
The Difference Between Optical Fiber Cable and Electrical Cable
In material: Cables use metal materials (mostly copper, and aluminum) as conductors; optical fibers use glass fibers as conductors.
In the transmission signal: Cables transmit electrical signals. Optical fibers transmit optical signals.
In the scope of application: Cables are now mostly used for energy transmission and low-end data information transmission (such as telephone). Optical fibers are mostly used for data transmission.
Optical fiber wire (OPGW wire and ADSS wire) operate between high-voltage transmission towers and optical fibers within the cables are used to transmit data for protection, control, and/or voice communications.
Transportation with Professional Service
Veri Cable company has multiple ways to protect your cables, sturdy and professional shipping packaging, and comprehensive insurance. Before shipping, our cables are packaged in wooden reels and corrugated box coils. During transportation, to protect the cable ends from moisture, we seal them with BOPP self-adhesive tape and non-hygroscopic.
Of course, we will send you the pictures during production and packaging. And we will deliver each order strictly according to the delivery time to ensure the smooth progress of the customer’s project.
In addition to the cables mainly introduced on this page, we also have ADSS cable (All Dielectric Self Supporting), if you have cable purchase needs, you can check the vericable website or email us, and we will have a professional cable sales representative to serve you.
As professional OPGW cable manufacturers, we support customized to your requirements. High-quality material at a low price and comprehensive OPGW installation services for you. Please feel free to contact us.
