Why Do Suspension Clamps Only Require 10–20% Of The Cable's Tensile Strength To Hold?

In transmission line and fiber optic cable suspension systems, the design purpose of clamp cable suspension clamp is not to bear the full tensile force like a tension clamp, but to ensure the stability of conductor suspension and contact. The gripping force of clamp aerial cable suspension clamps on the conductor is typically controlled at around 10–20% of the conductor's tensile strength; this is an engineering specification based on actual stress and operational requirements.

The internal structure of clamp angle suspension clamp, including U-bolts, pressure plates, and a housing, achieves frictional engagement with the conductor through a preset contact method, allowing the conductor to be properly suspended from insulators or crossarms without causing excessive indentation or damage due to excessive gripping force. Under normal operating conditions, clamp harga suspension clamp primarily bears vertical loads, while horizontal loads and external disturbances are usually borne by the conductor's own tension and the tower system; therefore, the gripping force requirement is significantly lower than that of hardware bearing the full tensile force.

This gripping ratio setting also benefits construction, installation, and subsequent maintenance. The lower gripping force allows installers to secure the wires more easily, and the messenger suspension clamp can be disassembled without excessive external force when the wires need to be inspected or replaced.
