Steel Suspension Clamp
A suspension clamp is a mechanical device used in overhead power line construction to securely support conductors while allowing limited movement to absorb mechanical stresses. It is designed to hold conductors without causing damage, maintaining line integrity under wind, tension, and vibration. Commonly used in transmission and distribution networks, the clamp is typically installed on crossarms or utility poles using bolts or pins.
Key Features:
- High mechanical strength for supporting heavy conductors
- Corrosion-resistant materials (galvanized steel or aluminum alloy) for long-term durability
- Smooth grooves or rubber inserts to minimize conductor wear
- Vibration and stress absorption to reduce fatigue damage
- Suitable for both bare and insulated conductors
- Easy installation with standard tools and minimal maintenance
- Designed for various conductor sizes and voltages
