AI Technical Summary
Misalignment in the installation position of the busbar trunking can lead to uneven contact between the conductive busbar and the connecting components, causing excessive local current density and overheating, which affects power transmission efficiency and accelerates the aging of the busbar trunking components.
The system employs horizontal and vertical fixing components. Through the cooperation of the limiting block and the limiting groove of the slider assembly, it adapts to the width of the busbar groove and maintains its straightness. At the same time, the busbar groove is tightened by springs to increase its firmness, and the vertical fixing component provides reliable support.
It effectively reduces the contact between the screw and air, extends the service life of the screw, ensures the stable operation and firm connection of the busbar, prevents the busbar from shifting, and extends the service life of the busbar.
