Description
Description:
The contact performance of the splicing connectors is related to the size of the contact resistance. The factors that affect the contact resistance are contact pressure, contact area and conductor material. The wedges of the upper and lower J elements are wedged into each other through the longitudinal tightening force of the bolts. After the installation is completed, the two J elements generate a transverse force on the conductor, causing the elastic deformation of the J element to act between the conductor and the wedge. Stable contact pressure between wedges. There is (multiple) point contact between the wire and the wedge, and there is surface contact between the wedges. The lateral friction when the wedge is wedged has a certain self-cleaning effect on the clamp itself and the conductor. These features ensure the connection performance of the J type pg clamp.
