Annular transformer

1.Application

Annular transformer core is made of quality cold-rolled silicon steel (0.35mm slice thickness is generally less), seamless rolled together, which makes it superior to the traditional core laminated iron core. Uniformly toroidal transformer coil around the core, the magnetic field lines generated by the coil and the magnetic core is almost completely overlap with the excitation energy and the laminated core loss compared to the decrease of 25%.
Product Details

2.Main Features

(1) electrical efficiency core without air gap, stacking factor of up to 95%, and core permeability desirable 1.5 ~ 1.8T (laminated iron core can only take 1.2 ~ 1.4T), electrical efficiency of up to 95% or more, empty only laminated load current of 10%.
(2) small size, light weight laminated transformer annular transformer than half the weight can be reduced, just keep core cross-sectional area equal to, annular transformer core is easy to change the length, width, height ratio, can be designed to meet the requirements of dimensions.
(3) less interference annular transformer magnetic core without air gap winding evenly around the ring on the core, this structure has led to small magnetic flux leakage, electromagnetic radiation is also small, can be used without additional shielding highly sensitive electronic device, such as an application in low-level amplifier and medical devices.
(4) low noise and vibration can reduce noise core without air gap.
