Toroidal Transformer Materials

Toroidal Transformer Process

Tianyi toroidal transformer is constructed in the following order

1.Core from 0.23mm thick silicon steel Japanese materials 23Q115 edges are ground smooth

2.Core protection from 4 layers polyester films (2 layers with 50% overlap)

3.Primary winding wire ( polyesterimid enameled QZY 180) and temperature class 180°

4.Primary leads from type UL1672 double insulation for 600V voltage and 105° temperature

5.Primary to secondary insulation from 6 layers polyester films (3 layers with 50% overlap)

6.Secondary winding wire ( polyesterimid enameled QZY 180) and temperature class 180°

7.Secondary leads from type UL1015 for 600V voltage and 105° temperature

8.Final insulation from 2 layers polyester films (1 layers with 50% overlap)
