supplementary information:
1) RI=reinforced insulation.
Concentric windings on single bobbin.
Core is
considered as primary.
Triple insulated wires used as secondary wi
nding.
Teflon tube used to separate the primary winding and secondary triple insulated wires where they are
crossing at 45
-90
o
angle.
All
lead pins were directly moulded in bobbin.
Two layers insulation tape wrapped around of core of transformer as suppl
ementary insulation.
Two layers insulation tape wrapped overlap of core near secondary pins side as supplementary insulation.
