EI Transformer Process
- EI lamination has 0.35mm and 0.5mm thickness, material has Z11/H12/H14/H18/H50 for option.
- The insulation for coil has 0.075/0.125mm thickness polyester film, 0.18/0.25mm DMD insulation paper and T410 Nomex paper. The brand of polyester films is DUPONT. The layers of overlap is depends 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
