Overview
HFW-40.5 outdoor pole mounted SF6 insulated load break switch is suitable for the distribution network with rated voltage of 12 / 24 / 40.5kV, rated current of 630A, frequency of 50 / 60Hz to open and close the load current and overload current in the power system, which can automatically isolate the fault distribution line section.
Product Details
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.
