Technical drawings
| Feature | Description |
|---|---|
| Outdoor pad-mounted design | Designed for outdoor ground-mounted installation, suitable for medium-voltage distribution projects where enclosed equipment access and field operation are required. |
| Dual secondary voltage output | Provides two secondary outputs in one transformer: 995 V for 500 kVA load and 480Y/277 V for 1000 kVA load, helping support different load groups on the same site. |
| 5-position tap changer | The off-circuit tap changer allows voltage adjustment before energization, helping match the transformer to actual site voltage conditions. |
| Bayonet fuse protection | The high-voltage side includes bayonet fuse protection, providing a clear and serviceable protection arrangement for pad-mounted transformer applications. |
| Defined insulation level | HV BIL 125 kV and LV BIL 30 kV are provided for insulation coordination review during project specification and technical approval. |
| Factory-tested before delivery | Factory tests cover winding resistance, insulation resistance, voltage ratio, no-load loss, load loss, impedance, withstand voltage, pressure integrity and insulating liquid condition. |
