CD type transformer is a kind of C core transformer. It is built by assemabed C core which is made of Hi-B oriented silicon steel strip. C core is assemabled by 2 U shape cores, and there is gap between two U shape cores. C core is also called cut core, because it looks like a rounded rectangle cutted at the center. Air gap is not always bad for transformers. Sometimes it does good. C core is good at making choke and audio output transformer, because of it's adjustable air gap. Certain air gap can reduce the flux saturation.
Prepare 2 coils and insert the core. That is simple. There is no need to insert EI laminations one by one like EI transformer.
The air gap in C core can be adjusted as you wish to make different applications.It is suitable to make choke and audio output transformer.
0.23mm, 0.27mm, 0.30mm Hi-B oriented silicon steel strip will be adopted to make sure the best magnetic performance. It is made by a continuous silicon steel strip, no break point. The cut surface is smoothly processed, certain air gap in the magnetic core can make the transformer not easy to saturated.
OFC(Oxygen Free Copper) copper wire applied in our C core transformers. OFC has no hydrogen embrittlement, and has a high conductivity. It is commonly used in audio equipment, vacuum electronic components, wire and so on.
From picking up a core, calculating an appropriate copper wire to delivery test, every single C type transformer should undergo very strict processing flow. Only strict processing technics can guarantee a high quality C type transformer. And only transformers from regular manufacturers can guarantee strict processing technics.
