Suspension Clamp for Cable

Suspension clamps are essential for supporting electrical lines that carry high voltages. They hold cables securely, ensuring safe energy distribution.

Suspension clamps are commonly used in construction for scaffolding and structural support. They provide stability and safety in both temporary and permanent installations.

In the communication field, suspension clamps support cables that connect cities and networks. These clamps are particularly important for fiber optic cables, which require careful handling to avoid damage.

Beyond electrical and construction applications, suspension clamps are also found in transportation and manufacturing settings. For instance, they may secure overhead conveyor systems or support structures in manufacturing facilities.

Clamp Body (Frame): This is the main load-bearing structure of the clamp, responsible for enclosing and supporting the conductor. It is usually made from high-strength metal alloys to ensure durability under mechanical stress.

Keeper (or Pressure Plate): The keeper holds the conductor tightly against the clamp body. It applies pressure evenly across the cable and is essential for maintaining a firm grip without damaging the conductor surface.

Straps or Hanger Links: These are used to connect the clamp to the insulator string or the pole cross-arm. They transfer the mechanical load from the clamp to the support structure.

Bolts and Nuts: High-tensile steel fasteners are used to secure all parts together. These bolts are responsible for applying the correct clamping force and are designed to withstand long-term tension and vibration.

Washers: Washers provide additional stability and ensure that the bolts distribute pressure evenly, especially when the surface isn’t perfectly aligned.

Aluminum Alloy: Lightweight, corrosion-resistant, and suitable for coastal or humid environments. Commonly used in high-voltage transmission systems due to its excellent conductivity and low maintenance.

Galvanized Steel: Known for its high tensile strength and lower cost. The zinc coating protects the base steel from rust, making it ideal for areas with heavy wind or ice loads.

Stainless Steel: Offers exceptional corrosion resistance in extreme environments like coastal zones, chemical plants, or industrial areas. It also maintains structural integrity over long service life spans.

Composite Materials: Used in advanced or insulated applications, especially where electrical isolation or vibration damping is needed. These materials are lightweight, weather-resistant, and electrically non-conductive.
