Core & Coil Assembly parts diagram: 1 core laminations, 2 primary winding, 3 secondary winding, 4 electrostatic shield, 5 coil spacer. 5 parts in 5 top-level items. — Core & Coil Assembly parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Core Laminations	1×	0.3 mm grain-oriented silicon steel laminations, stacked and banded in cruciform shape
2	Primary Winding	1×	12 kV primary coil, multi-turn solid or stranded copper wire, Class H insulation (180 °C)
3	Secondary Winding	1×	480 V or 277 V secondary coil, larger wire gauge (lower impedance), stepping down voltage
4	Electrostatic Shield	1×	Grounded copper foil or winding shielding HV from LV, reducing capacitive coupling and transient impulses
5	Coil Spacer	1×	Wooden or epoxy spacers separating primary and secondary coils, maintaining dimensional stability
