CONSTRUCTION NOTES
- C LV and HV copper masses are per phase. The C tank total adds each once; this assembly contains three windings of each kind. The C totals are retained in the source snapshot and are not treated as the CAD assembly mass.
- Winding solids represent copper/insulation packs. Their geometric volume must not be multiplied by pure copper density. Copper mass is separately assigned from the C winding calculation.
- Core packet cross-section is area-matched to C gross area. Packet schedule and butt-joint geometry are construction assumptions, not a fabrication lamination schedule.
- The C core mass uses gross area and steel density. CAD repeats that convention; insulation between laminations is not resolved.
- C tank dimensions are interpreted as the clear internal cavity. Exterior walls, flange, cover, cooling tubes and fittings increase overall size.
- Bushings, clamps, lead routing, conservator and hardware are assumed general-arrangement components. Dielectric, pressure, weld and mechanical design are not certified by their geometry.
- Nominal oil domain is a display aid, excluded from STEP and mass totals; it is not a boolean-subtracted oil-volume calculation.
- Cooling tube heat-transfer height follows the C parameter; bends and connection details are CAD assumptions.
- Star-connected windings display an accessible neutral bushing; delta windings display three bushings. Internal vector-group jumpers and neutral lead topology are not resolved.
