EE25.4 High-Frequency Transformer Manufacturer Customized DW3406
EE Transformer applied in the switching power supply,main power
transformer
Features of our power transformer:
Our transformers are automatic cable and layers of insulation.
Our transformers are producted with high-temperature high-strength
copper enameled wire and good quality silicon steel sheet,
They are small size,safe and reliable wiring,high degree of
protection
They are able to work in the rated load long-term effective.
Quality assurance of our power transformer:
1. The main materials used in our transformer are copper and steel,
both of which are getting scarcer with cost increases as a
consequence.
2.No impregnation is needed to keep the laminates quiet so this
potential environmental hazard is avoided
3. The utility model has the advantages of small size, safe wiring,
high protection level, good performance, etc., and can work
effectively in rated load for a long time.
OEM ODM is of course Accepted.
