Optical Power Ground Wire
- It has two functions, one is as a lightning protection line for transmission lines, providing shielding protection for transmission lines against lightning strikes and discharges. The other is for video, data and various control signals to form a multi-channel broadband communication network.
OPGW fiber optic cables in luftledningar generally have skeleton type, center tube type and layer stranded type. It is mainly used for lines with voltage levels of 100kV, 220kV and 500kV. It is easy to be affected by line blackout, safety and other factors, and is mostly used for new lines.
OPGW Cable More 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 till 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 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 till 2 layers of monofilament.
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 eller 2 layers of monofilaments, which can be all aluminum-clad steel wire or a mixture of aluminum-clad steel wire and aluminum alloy wire.
Rust Steel Tube Structure OPGW - Layer Stranded
The stainless-steel tube is twisted with 2 till 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 till 2 layers of monofilament, which can be all-aluminum-clad steel wire or a mixed-stranded aluminum-clad steel wire and aluminum alloy wire.

Key Features of OPGW Cables
VERI OPGW cables are mainly used in communication, monitoring, and data transmission of power transmission lines, which can effectively improve the safety, stabilitet, and intelligence of the power system.
- Säker och pålitlig: OPGW fiberoptiska kabels goda isoleringsprestanda och anti-interferensförmåga kan effektivt säkerställa säker och stabil drift av kraftsystemet.
- Energibesparing och miljöskydd: användningen av fiberoptisk kabel för att överföra signaler, minska användningen av koppartrådar i kraftsystemet, och minska energiförbrukningen och miljöföroreningarna.
- Bekvämt underhåll: Underhåll och hantering av OPGW fiberoptiska kabel är relativt enkel, avsevärt minska underhållskostnaderna och arbetsbelastningen.
- Stor kommunikationskapacitet: OPGW makt fiberoptisk kabel kan realisera hög hastighet, kommunikationsöverföring med stor kapacitet, lämplig för en mängd olika tillämpningsscenarier i kraftsystemet.
Allmänt, the number of optical fibers of OPGW fiber optic cable will depend on the specific needs, och the common specifications are 24 kärnor, 36 kärnor, 48 kärnor, och så vidare. The more the number of optical fibers, the stronger the communication ability of the cable.
OPGW Cable Diameter: The diameter of OPGW fiber optic cable is an important parameter affecting its installation and laying. The smaller the diameter of the fiber optic cable, the less space, and resources required for installation, while also reducing the impact on existing facilities. Existing facilities. Därför, when selecting optical ground wires, it is necessary to consider the diameter of the cable to match the actual laying conditions. OPGW cables need to be considered when selecting cables for laying.
Applications of OPGW Cables in Power Systems
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 an operating temperature of -40 —70 ℃
