EMT’s Oil type Load Break Switch with the ARC unit of the perfect extinction performance distribution level gang operated side-break switches for 15kV through 35kV on the overhead distribution feeders and outdoor distribution System.
The Oil Type LBS have been specially designed for these live-switching duties :
♦ Line Switching for Load Current (Parallel / Loop Switching), Load Transfer Switching.
♦ Transformer Magnetizing Current Switching-load currents.
♦ Cable Charging Current Switching.
EMT’s Oil Type LBS equipped Oil type High performance Arch Extinguishing Chamber and Switching Operation with Manual, or Motorizing .The Motorizing Type LBS can be operated remotely with EMT’s RTU by SCADA system DNP 3.0, or IEC 101 Protocol
1) High Reliability
Main circuit switching parts of the switch are in the steel-made hermetically-sealed enclosure which ensures the
high rust-proof performance, therefore the switch can not be affected by the outdoor atmosphere.
Moreover, the switch has long life and consequently it is free of maintenance.
2) Flexible Installation and Operation
Operation : Manual, or Motorizing Operation ( Available operation with SCADA system).
* Automatic Trip & Closing as Reclosing Sequence : Optional
Switching ; Close (Close Handle ), Open (Open Handle) by Hook Stick
Mounting ; Horizontal Mounting on Pole mounted
In addition, the switch does not generate the regnition, re-strike and the abnormal voltage in making and breaking current.
