Here are Application scenarios for different types of power line clamps:


1. Utility Pole Double-Bolt Clamp 


Used to secure crossarms and insulator brackets to the main body of transmission/distribution utility poles, commonly applied in the installation of pole-mounted equipment for 10kV and lower distribution lines.


2. Cable Hoop Clamp 


Fits the outer diameter of overhead cables, securing low-voltage service cables or communication lines at the branch positions of utility poles to prevent cable abrasion caused by wind-induced sway.


3. Crossarm Mounting Clamp 


Used to fix the main crossarms of utility poles in long-distance transmission lines, bearing the combined load of crossarms, insulators, and conductors. It is commonly used in 35kV transmission lines.


4. Equipment Mounting Clamp 


Fastens the brackets of pole-mounted transformers, metering boxes, and other electrical equipment to the upper part of utility poles, requiring alignment with the mounting holes of the equipment brackets.


5. Branch Pole Clamp


Used to secure small brackets for branch lines on main utility poles, matching smaller branch pole diameters (usually ≤150mm). It is commonly found at branch points of rural low-voltage distribution lines.
