Optical Power Ground Wire

Structure of opgw fiber optic cable manufactured by ZMS cable
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 in transmission lines 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.

VERI OPGW Cable Advantages

VERI OPGW cables are mainly used in communication, monitoring, and data transmission of power transmission lines, which can effectively improve the safety, stability, and intelligence of the power system.

  • Safe and reliable: OPGW fiber optic cable’s good insulation performance and anti-interference ability can effectively ensure the safe and stable operation of the power system.
  • Energy saving and environmental protection: the use of fiber optic cable to transmit signals, reduce the use of copper wires in the power system, and reduce energy consumption and environmental pollution.
  • Convenient maintenance: OPGW fiber optic cable maintenance and management is relatively simple, greatly reducing maintenance costs and workload.
  • Large communication capacity: OPGW power fiber optic cable can realize high-speed, large-capacity communication transmission, suitable for a variety of application scenarios in the power system.

Generally, the number of optical fibers of OPGW fiber optic cable will depend on the specific needs, and the common specifications are 24 cores, 36 cores, 48 cores, and so on. 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. Therefore, 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.

VERI OPGW Fiber Cable Application

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 ℃
