Technical drawings
| Station-type structure with separated HV and LV connection areas | Provides a clearer wiring layout for field installation, inspection, and maintenance in substations, industrial facilities, and station service systems. |
| Dyn1yn1 vector group with X/Y low-voltage terminal arrangement | Provides a defined secondary-side terminal layout for distribution systems that require grouped LV connections rather than a simple single-secondary output structure. |
| 5-position off-circuit tap changer | Allows primary-side voltage adjustment when the transformer is de-energized, helping match actual site voltage conditions during commissioning or operation. |
| FR3 non-PCB insulating fluid | Used for insulation and cooling in the liquid-immersed transformer system while meeting non-PCB insulating fluid requirements. |
| HV porcelain bushings, 5 kV class, 60 kV BIL | Provides the primary-side medium-voltage connection and insulation level suitable for a 4.16 kV system. |
| LV 4-hole spade terminals, 1.2 kV class, 30 kV BIL | Supports bolted connection to busbars or cable terminals on the 480Y/277 V secondary distribution side. |
| Oil level gauge, temperature gauge, pressure indicator, and pressure relief device | Allows operators to check oil level, temperature, and pressure conditions during routine inspection, while providing basic pressure relief protection. |
| Drain valve and sampling access | Supports insulating fluid sampling, testing, and maintenance during service life. |
