How Should Parallel Groove Clamps Cope With Wind-induced Vibration?

The basic structure of parallel groove clamp employs a parallel groove design, with two metal structures joined by a bolted assembly to provide stable mechanical clamping for maintaining the relative position of the conductors. The grooves on the inner side of parallel groove connector are shaped according to the conductor diameter, resulting in a wider metal-to-metal contact surface, reducing contact resistance and improving connection consistency.

To address conductor swaying caused by wind vibration, the clamping material and fastening method must be considered in the design of aluminium pg clamp. Materials such as aluminum alloy and galvanized steel are commonly used to manufacture the body of bimetal pg clamp, balancing weather resistance and service life. The connection method, which does not rely on welding or permanent deformation, allows blackburn parallel groove clamp to maintain gripping force under repeated loading conditions.
