Toroidal Transformer Main Materials (IQC process)
All the material is inspected strictly with ISO9001:2008 quality program.
Core: appearance inspection and core loss test.
Copper wire: pinhole test and coat of adhesion test

UL CE Toroidal Transformer 220V 110V to 12V 24V Transformer

Toroidal Transformer Process
1. Core is from 0.23mm thick silicon steel Japanese material 23Z100.
2. Core is protected from 4 layer polyester films with 0.075mm thick (50% overlap 2 layers). The brand of polyester films is DUPONT.
3. Primary winding wire is polyesterimid enameled, have 130/155/180degress for choice.
4. Primary lead wire from type UL1617 double insulation for 600V voltage and 105 degree.
5. Insulation between primary and secondary is overlap 67% 2 layers , 4 layers polyester films or 50% 4 layers, 8 layers polyester films. It is subjects to different safety agency requirements. The brand of polyester films is DUPONT.
6. Secondary winding wire is polyesterimid enameled, have 130/155/180degress for choice.
7. Secondary lead wire from type UL1015 for 600V voltage and 105 degree.
8. Outer insulation is overlap 50% 1 layers, 2 layers polyester films. The brand of polyester films is DUPONT.

Transformer Testing Items
1. Exciting current & core loss: 100% test
2. DC Resistance: 100% test
3. Layer insulation: 100% test
4. Loading test: 100% test
5. Hi-pot test: 100% test, but the time is only approx 10seconds for the production-run.
6. Aging test: Spot check, 10% of product quantity
