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  

 

 

FEATURES

 

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.
