Process

Toroidal Transformer Main Materials (IQC process)

All the material is inspected strictly with ISO9001:2015 quality program.

Core: appearance inspection and core loss test.

Copper wire: pinhole test and coat of adhesion test

Toroidal Transformer Process

Core is from 0.23mm thick silicon steel Japanese material 23Z100.
Core is protected from 4 layer polyester films with 0.075mm thick (50% overlap 2 layers). The brand of polyester films is DUPONT.
Primary winding wire is polyesterimid enameled, have 130/155/180degress for choice.
Primary lead wire from type UL1617 double insulation for 600V voltage and 105 degree
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.
Secondary winding wire is polyesterimid enameled, have 130/155/180degress for choice.
Secondary lead wire from type UL1015 for 600V voltage and 105 degree
Outer insulation is overlap 50% 1 layers, 2 layers polyester films. The brand of polyester films is DUPONT.

Transformer Testing Items

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

Assembly Means

Two mounting way for choice.

1. Rubber + Metal disk Assembly

2. Epoxy in the centre
