Beschreibung
Summary
Pole-mounted load break switch(pole-LBS) applies up to 36KV 400/630A, 50Hz pole-LBS associated with a state of the art controller. This SF6 gas-insulated switch can corporate with the distribution automation system, and also isolate a faulted section of distribution line from the control center.
A simple pole-mounting arrangement contribute to quick and low cost installation, and the switch can be operated manually with a electronic controller. Electronic controller is contained in a stainless steel cabinet for an all weather environmental conditions. Remote monitoring and control can also be provided mounting wire or wireless modem in a cabinet.
