To determine the height of the connector box and the cable frame for Optical Power Ground Wire (OPGW) cables, several factors and specifications must be considered.
Connector Box Height
1.Installation Height: The OPGW joint box should be installed at a height ranging from 8 meters to 10 meters above ground level. This ensures optimal performance and accessibility across the transmission line.
2.Uniform Positioning: It is essential that the installation position of the connector box is uniform across the entire line to maintain consistent performance and reliability.
Cable Frame Height
1. Cable Sag Considerations: The height of the cable frame will also depend on the sag of the OPGW cable, which is influenced by factors such as temperature, tension, and span length. Generally, sag should be controlled to avoid excessive bending or stress on the cable.
2. Tower Design: The design of the supporting towers or poles needs to accommodate the required height for both the connector box and the cable frame. This includes ensuring that the bending radius of the cables is not less than manufacturer specifications, which typically require a minimum radius to prevent damage.
3. Environmental Factors: Consideration must also be given to environmental conditions such as wind load and ice accumulation, which can affect both sag and tension in OPGW installations.
In a word. we should consider the beolw 2 factors at least:
- Connector Box Height: 8 to 10 meters.
- Cable Frame Height: Dependent on sag and environmental conditions; must ensure compliance with bending radius specifications.
To determine the height of the connector box and cable frame for OPGW cables, we need to account for cable specifications, environmental conditions, installation requirements, and industry standards. Combining these factors will help determine the appropriate dimensions for the connector box and frame to ensure safe and effective operation. By adhering to these guidelines, we can effectively determine the appropriate heights for both the connector box and the cable frame in OPGW installations.
