R core transformer
R core transformer is a new kind of dry type transformer. the magnetic core of R core transformer is made from continuous silicon steel strip, and the cross section is round, like O core transformer. R core transforer has the advantages of low noise, low flux leakage, low no-load current, low loss, and high efficiency. R core transforer is a kind of copper saving transformer, needs less copper for each turn. It has greater explosive power than toroidal transformer. The bobins of R core transformer are made of PBT plastic, which has a strong dielectric strength and fire resistance. R core transformer is widely used in industrial control, home appliances, hi-fi audio equipment, signal equipment, office device, communication apparatus, test instrument and medical instrument.
High dielectric strength
The windings are evenly distributed in 2 different bobbins, it is much more convenient to make high voltage transformer by seperate one winding into several layers.
Low noise
R core transformer has high isolation degree. it can improve the signal-to-noise ratio, isolate the harmonic interference, reduce the noise, make he background cleaner. R core transforer can fully improve the quality of sound.
R core
0.23mm, 0.27mm, 0.30mm Hi-B oriented silicon steel strip will be adopted to make sure the best magnetic performance. the magnetic core is made by a continuous silicon steel strip, no break point. The flux path is continuous, no gap and less flux leakage, which guaranteed the high magnetic performance.
Copper wire
OFC(Oxygen Free Copper) copper wire applied in our R 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.
Workmanship
From picking up a core, calculating an appropriate copper wire to delivery test, every single R core transformer should undergo very strict processing flow. Only strict processing technics can guarantee a high quality R core transformer. And only transformers from regular manufacturers can guarantee strict processing technics.
