with good safety practice and the handling of
high-voltage electrical equipment.
GENERAL
Cooper Power Systems' RTE
are used in underground residential applications with
loop feed, and in three-phase commercial industrial
installations where the ability to use an alternative source
of power is necessary. They can also be used to switch
on and off a primary cable tap on a transformer.
RTE sectionalizing switches rotate 360° in either
direction for alternate source selection. A spring-loaded
activating mechanism ensures quick loadbreak action
and positive contact engagement through all positions.
The under-oil switch can be installed near the
transformer core/coil assembly, thus minimizing cable
capacitance. With cable capacitance minimized and all
three phases switched simultaneously, the likelihood of
ferroresonance is greatly reduced. Sidewall or cover
mounted switches are hotstick operable and available in
six different blade configurations for one, two or three
pole connections.
