Why VCB and SF6 breakers to be used in HT used by cant ACB
of higher rating to be used for 11kv and 33kv.
Answer Posted / baskaran.r
in an acb the distance between terminals are fixed for 415
volts. for higher voltages this need to be much larger.
there are some makes acbs are available in 3.3 kv with
increased gap to the tune of 2 feet. For higher voltages the
gap required will be very much higher.arc handling will be
impossible in higher voltages
