Transformer Insulation Material
We’ve been hearing a lot of emphasis on insulation material
for capacitors, wires and such. What about output transformers? Yes, it is the
same! Transformer insulation material matters.
Traditionally, Kraft paper is always used. Nowadays, with
new (well, not so new really) materials are available due to technological
advance on materials processing, like Kapton, Nomex and Teflon for insulation
materials. These materials bring new variations to transformer making, and it
will greatly impact the end results, good or bad.
Insulation material, as what it is named, is to insulate the
conductors. When it comes to insulation, we need to analyze the electrical
characteristics of the material to properly evaluate the design implementation
of the output transformer as that would affect the input / output electrical
characteristics.
