Load-bearing Mechanism And Mechanical Characteristics Of Parallel Groove Clamps

parallel groove adopts a compression structure design, using a special tool to crimp the two wires together. During the crimping process, the aluminum on the inner wall of parallel groove clamp connector undergoes plastic deformation, embedding itself into the stranded gaps of the outer layer of the wire to form an effective contact surface. This structure allows the gripping force between the conductor and the pg clamp connector to be approximately 20%-65% of the conductor's calculated breaking strength, with the specific value depending on the pg clamps model and the crimping process parameters.

The single bolt parallel groove connector's ability to hold wires comes from contact at multiple levels. First, under external pressure, the active oxide layer at the interface of the two conductors is compressed and ruptures, allowing aluminum electrons to form conductivity between the surfaces. Second, the aluminum on the inner wall of model parallel groove clamp undergoes plastic deformation, entering the stranded gaps of the conductor, significantly increasing the contact area and thus improving overall conductivity. This multi-layered contact mechanism ensures that the conductor's own weight is adequately supported and conducted at the connection point.
