Choosing a suitable cable suspension clamp is a process that comprehensively considers the characteristics of the cable, environmental conditions, and installation requirements. The following are some key factors and steps:

1. Understanding the specifications of optical cables: Firstly, it is necessary to clarify the type of optical cable (such as ADSS, OPGW, etc.), outer diameter, ultimate tensile strength, and operating span of the optical cable (i.e. the distance between two support points). Different types of optical cables have different requirements for suspension clamps due to their differences in structure and performance.

2. Evaluate environmental factors: Consider the climatic conditions (such as wind speed, temperature range, humidity, salt spray corrosion, etc.) and geographical characteristics (such as whether it crosses rivers, valleys, urban streets, etc.) in the area where the optical cable is installed, which will affect the material selection and design type of the suspension clamp.

3. Determine the span and corner: Select the appropriate type of cable clamp based on the operating span of the optical cable. For example, short spans (such as less than 200 meters) may require tangent wire clamps or single-layer pre twisted suspension wire clamps, while long spans (such as 200 meters to 1000 meters or more) may require double-layer pre twisted wire or specially designed suspension wire clamps.

4. Consider the outer twisting direction: Especially for OPGW optical cables, the rotation direction of the twisted wires inside the clamp should be opposite to the outer twisting direction of the optical cable to increase friction and stability. If the outer layer of the optical cable is left-handed, special instructions should be made when ordering.

5. Choose appropriate accessories: Based on the type and design of the suspension points of the tower, choose suitable connection fittings, such as U-shaped screws, U-shaped hanging rings, UB type hanging plates, etc., to ensure a firm connection between the wire clamp and the supporting structure.

6. Pay attention to the structure and materials of the cable clamp: High quality suspension cable clamps should include corrosion-resistant aluminum alloy clamps, high elastic rubber gaskets, high-strength pre twisted wires and other components to ensure good protection and long-term stable suspension of the optical cable.

7. Follow manufacturer's instructions: Refer to the technical parameters and installation guidelines provided by the manufacturers of optical cables and suspension clamps to ensure that the selected clamps comply with product standards and industry specifications.

8. Consider installation and maintenance: Choosing suspension clamps that are easy to install and maintain can reduce construction costs and the complexity of future repairs.

In summary, selecting a suitable suspension clamp for optical cables is a meticulous and professional process that requires comprehensive consideration of the characteristics of the cable itself and external environmental factors, adherence to industry standards, and ensuring the safe and stable operation of the cable.
