What are the different types of OPGW fittings?
OPGW fittings are essential components of overhead fiber optic cables. These fittings can vary in shape and size, depending on their function, installation requirements and the specific cable configuration. Therefore, understanding the characteristics of different OPGW fittings can help you determine which fittings you need and how they will work for your specific cable project.
1. Dead-end assemblies.
Dead-end assemblies, also known as tension sets, are fittings that are used to anchor OPGW cables at the end of the line. They are commonly used for overhead transmission and distribution lines since they provide a strong and secure anchor for the cable. The use of tension sets minimizes the stress on the OPGW cable when it experiences changes in temperature or wind gusts.
2. Splice closure boxes.
Splice closure boxes are used for splicing OPGW cables. They are critical fitting components of the OPGW system, and they must be designed to handle harsh environmental conditions like extreme temperatures, high humidity, and saltwater spray.
3. Suspension clamps.
Suspension clamps are installed at regular intervals to support the weight of the OPGW cable. They also help to prevent the cable from sagging under its weight and improve its stability. Suspension clamps ensure that the OPGW cable stays in place and that it does not move too much due to wind or heavy usage.
4. Running.
Running fittings are installed along the length of the OPGW to provide additional support and improve the cable's strength. They are used in areas where the cable is likely to be exposed to heavy winds, rain, snow, or other harsh weather conditions. Running fittings can be used in combination with suspension clamps to enhance the overall stability of the cable.
5. Vibration dampers.
Vibration dampers are used to reduce the risk of galloping, which is a common problem with overhead electrical and fiber optic cables. Galloping occurs when wind gusts cause the cable to move up and down rapidly, resulting in the loss of signal transmission. Vibration dampers help to reduce the movement of the cable, which, in turn, reduces the risk of signal loss.
In conclusion, understanding the different types of OPGW fittings is critical to ensuring the successful installation and performance of overhead fiber optic cables. It is important to identify the specific type of OPGW fitting that is appropriate for your project and to ensure that it is installed correctly. OPGW fittings from reliable suppliers are recommended since they are manufactured to meet the standards for high-quality and long-lasting equipment.
