what are the differenc between vcb and sf6 breakers
Answer Posted / kunjan singh
VCB can be used for upto 33 KV ,due to difficulty in
maintaining the vacuum inside a VCB at higher voltage,,and
also ,there are some size limitations...nowadays,at all
voltage level we can use SF6 CB having pressure of 5 to 6.5
kg/cm2..
