Suspension and support clamps are essential components in powerline transmission hardware. They are used to securely hold and support power lines, ensuring their stability and reliability. Here’s an overview of their functions and types:
▶ Suspension Clamps: Suspension clamps are used to hang or suspend power lines from towers or poles. They provide vertical support and allow for controlled movement of the conductors due to factors like wind or thermal expansion. Suspension clamps typically consist of a metal or composite body that holds the conductor and attaches to the supporting structure using bolts or other fasteners.
▶ Support Clamps: Support clamps are designed to hold conductors on the top of an insulator as they pass around poles or towers. They provide lateral support to the conductor, preventing excessive movement and maintaining proper alignment. Support clamps come in various designs, including singlebolt or double-bolt configurations, and are made from materials that offer high strength and resistance to environmental factors.
When selecting suspension and support clamps for powerline applications, several factors must be considered, including the type of conductor, operating voltage, environmental conditions, and mechanical requirements. The choice of materials, such as steel, aluminum, or composite, is crucial to ensure the clamps’ durability and resistance to corrosion.
