C Type Transformer

The C TYPE TRANSFORMER, the core of the transformer is C-shaped and two C-shaped cores can be combined to a closed core with a mouth shape. The material of the core is usually cold rolled silicon steel sheet. It has the advantages of small magnetic leakage, small size and core structure. So, it is often used to make a variety of small transformers. The operating principle is the same as the general transformer. When there is AC current in the primary coil, An AC magnetic flux is created in the core to induce a current in the secondary coil, to change the output voltage.  

As a common transformer, C Type Transformer has the following characteristics:
1. High safety performance, low loss and low noise.
2. Heat dissipation performance is well.
3. The size is small, weight is light and easy assembly.

That is why widely used in various electronic and industrial equipment.

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

Transformer Process

• 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.

Transformer Testing Items

• Exciting current & core loss: 100% test
• DC Resistance: 100% test
• Layer insulation: 100% test
