Pad Mount Switchgear
Pad Mount Switchgear
General Features
Pad mount switchgear is designed
for distribution automation system
with combination of circuit breaker,
load break switch and direct circuit.
Multiple selection of load break
switches and circuit breakers make
the end user`s distribution line
system more flexible.
SF6 gas insulated switchgear and
Solid insulated switchgear will
provide full support with various
choice of controls in order to
complete distribution line system.

Technical Features
1. Control
Circuit Breaker/Load Break Switch controller, Protection Relay, FRTU, Modem can be placed
Remote operation available (Built-In RTU : Option)
2. Load Break Switch(LBS)
All circuit has independent operation function
Each circuit has one operation hole to Close/Open/Earth
Status Indicators of circuit breaker and load break switch are available
Prevention of switching from Close to Earth by using 3 Position operations for LBS
Operation Counter
* 3-position operation
Dual contacts : Enhanced Making and Disconnecting capacity
Increased contact distance of Open status results the increment of Insulation capacity
Due to Close-Open-Earth turn operation, mis-operation is prevented and
provide Natural Locking structure
Long life of contacts due to dual contact(divided arcing, less wear-out)
* Solid Insulation type Load Break Switch
Polymer insulation not by SF6 gas
Environment Friendly
