The knee-type disconnector consists of one articulated arm which, by moving “horizontally” on the plane of the insulators, closes the circuit on a fixed contact located on the side insulator.
Since the movement of the arm takes place on the same plane as that of the insulators, the phase-to-phase spacing is minimized.
Compared to the vertical-break disconnector (SLOB), the dimensions of the knee-type model in open position are reduced, thus allowing for top metal structures (if any) to be placed at lower heights.
