The iron cores can be customized according to the user's size and performance requirements, adopting the crafts such as coiling, laminating, rivet stacking, self fastening and rubber molding. This kind of iron cores has excellent magnetic performances of super high initial permeability and high permeability, super low coercivity and low saturation magnetic induction
They are suitable for the application in weak magnetic field, can be used for manufacturing high sensitivity and small power transformer, low power magnetic amplifier, relay, head of magnetic recording device, zero sequence current transformer, power converter, precision current transformer, magnetic amplifier, power transformer, choke, pulse transformer, change polarity pulse transformer, DC voltage converter, magnetic modulator, constant inductance element, unipolar pulse transformer, magnetic shielding, and so on.
C-type:
Structural features: Because its structure is two halves put together to form a closed magnetic circuit, it is an open structure. Therefore, the coil can be made separately from the core, and then the coil is put on the core, so the production period can be shortened.
Application: Super C cores of various specifications are widely used in new energy fields such as wind power generation systems, solar photovoltaic, high-speed railroads, and so on.
ED-type:
Structural characteristics: Because of its structure for the three-phase two halves together to form a closed magnetic circuit, for the open structure. Therefore, the coil can be produced separately from the iron core, and then the coil is put on the iron core, so the production period can be shortened.
Application: Widely used in three-phase transformers, reactors, chokes and other electromagnetic components in electronic and electrical equipment.
Silicon core can be customised
