Process

EI 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

EI Transformer Process

EI lamination has 0.35mm and 0.5mm thickness, material has Z11/H12/H14/H18/H50 of option.
The insulation for coil has 0.075/0.125mm thickness polyster film. 0.18/0.25mm DMD insulation paper and T410 Nomex paper. The brand of polyster film is DUPONT. The layers of overlap is deponds on the safety agent requirements.
Primary and Secondary winding wire is polyesterimid enameled, have 130/155/180/200degree for option.
Primary lead wire from type UL1617 double insulation for 600V voltage and 105 degree or UL3321 XLPE for 600V and 150degree.
Secondary lead wire from type UL1015 for 600V voltage and 105 degree.
Outer insulation is overlap 1 layer 0.075/0.125mm thickness polyester film or 0.18/0.25mm DMD insulation paper or T410 Nomex paper.

EI 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
