Electrical Power Transformer Manufacturer.Choke Coil Supplier.
We provide reliable, energy-efficient design to meet energy efficiency requirements and specialize in supplying low voltage,high frequency electric transformers. Offering a wide range of common mode choke, choke coil design.
  • Choke Coil Transformer Laminations The coils are firstly wound on a former which has a cylindrical, rectangular or oval type cross section to suit the construction of the laminated core. In both the shell and core type transformer constructions, in order to mount the coil windings, the individual laminations are stamped or punched out from larger steel sheets and formed into strips of thin steel resembling the letters “E’s”, “L’s”, “U’s” and “I’s”. For example, two “E” stampings plus two end closing “I” stampings to give an E-I core forming one element of a standard shell-type transformer core.
