American-BOX TYPE CAGE OFF-CIRCUIT TAP SWITCH
This tap changer is mainly used for combined type (base type) transformer,which is called as “American-box type”in our country. It must tap and change under off-circuit status, and is used to finish voltage regulating function of primary coil.
American-BOX TYPE CAGE OFF-CIRCUIT TAP SWITCH- Used in mineral oil or silicon oil
- Rated Voltage 10KV-36KV
- Rated current from 63A-125A
- Tapping position: 3-5
- Regulation 2.5% per position
