Toroidal transformer

Toroidal transformer is a kind of electronic transformer. It's been widely used in home appliances and other electronic equipments which require high performance. The main usage of toroidal transformer are as power transformer and isolated transformer. We have full series of toroidal transformer, and the scale of our manufacturing is big. Our toroidal transformer can satisfy customers from not only domestic but also abroad. In domestic, toroidal transformer is widely used in audio equipment, auto control equipment and quartz lamp. Toroidal transformer is a kind of cost-effective transformer, which has good performance with relatively low price. toroidal transformer also has good output performance and reliability, so toroidal transformer is a kind of competitive transformer.

Low noise

The core of toroidal transformer has no air gap, so there will be less induced shaking noise. And copper wires embrace the core tightly, which effectively reduced the hum noise.

Low temperature rise

Toroidal transformer has high efficiency .The core loss of toroidal transformer is low. The windings, which worked on a low temperature core, can obtain an effective heat radiation.

Toroidal core

Hi-B oriented silicon steel sheet, thickness 0.23mm, 0.27mm, 0.30mm would be adopted. Toroidal core with closed magnetic path has less flux leakage, which make sure it has the most advanced magnetic performance. With the help of loop wire winder, toroidal transformers can be manufactured quickly. We have various kinds of material, which can guarantee different needs of our customers.

Copper wire

OFC(Oxygen Free Copper) copper wire applied in our toroidal 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 toroidal transformer should undergo very strict processing flow. Only strict processing technics can guarantee a high quality toroidal transformer. And only transformers from regular manufacturers can guarantee strict processing technics.
