This ANSI transformer bushing series covers 15 kV and 25 kV ratings with current options from 125 A to 600 A. Catalog variants use 2-hole, 4-hole or 6-hole terminal pads and 6-shed or 7-shed profiles. The comparison table lists each model together with its dimensions, conductor thread, mounting-hole arrangement, creepage distance and reference code. Any source-table inconsistency is identified in the note column.
Series Overview
- Voltage range: 15–25 kV
- Current range: 125–600 A
