Cable switch module and Busbar sect

Cable switch module and Busbar sectionalizer with load break switch
(C-mechanism)
The mechanism (3PKE) has two operating shafts; the upper one for the load break
switch and the lower one for the earthing switch.
Both shafts are single spring operated and operate one common shaft which is
directly connected to the three position switch (CFE-C) inside the SF6 tank. When
both load break switch and earthing switch are in open position, the switch satisfies
the specifications of disconnector.
Due to the mechanical interlock between the upper and lower operating shaft, it is
impossible to operate the load break switch when earthing switch is in earthed
position or operate the earthing switch when the load break switch is in closed
position.
