3.8. CONTROL CUBICLE
The Recloser control cubicle is designed for outdoor pole mounted and substation operation which
is made of anti-corrosion stainless steel.
The door is locked with three position locking devise and sealed with replaceable urethane foaming
packing.
All vents are screened against vermin entry and the cubicle inside is fully covered with adiabatic
faming material which protects the inside components from the rapid temperature variation.
The control cubicle outside is protected with a sunshine shield cover which is required for keeping
the life cycle from shortening because the temperature sensitive electronic components and battery
is affected by sunshine heating.
The microprocessor based control compartment is completely sealed against water entry even
though the hatch door is opened in the rain during the recloser operation.
The condensation of the cubicle inside can be expected to foam due to the temperature variation
under the atmospheric conditions such as tropical and moderate climate, however, any
condensation does not affect any electronic components arranged with fully insulated sealed and
well vented design.

Consequently, any condensation on metal surface will run out of the bottom and automatically
dried without affecting the electronic modules by ventilation and self heating.
The standard control cubicle contains the relay, batteries for control power and mechanism driving
power.
