OPGW Cable -24B1-123 [88.5;81.0]

OPGW Optical Fiber Cable in Nepal


The term "OPGW-24B1-123 [88.5;81.0]" represents a specific type of Optical Ground Wire (OPGW) cable. Here's a breakdown of what each part of the term typically indicates:

OPGW: This stands for Optical Ground Wire, which is a type of cable used in overhead power transmission lines. OPGW cables serve a dual purpose by carrying electrical power and providing a path for data transmission through optical fibers integrated into the cable structure.

24B1: This part likely indicates the construction or design of the cable. Specifically, it may represent that the cable contains 24 optical fibers arranged in a certain configuration. The "B1" portion could denote a specific arrangement or type of strength members or other components within the cable.

123: This could denote a specific model or variant of the OPGW cable. It might represent characteristics such as cable diameter, materials used, or other design features. Without additional context or specification information, it's challenging to provide a precise interpretation of this part.

[88.5;81.0]: This represents the diameter range of the cable in millimeters. The numbers within the brackets typically indicate the minimum and maximum diameters of the cable.
