The coil is wound with copper wire or foil, reinforced with glass fiber, epoxy resin without filler, vacuum drying, degassing and dehumidifying, integral casting, high mechanical strength, short circuit resistance, and strong impact resistance.
Three-phase dry transformers are the main components of various power supplies and electrical equipment. It is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core).
A transformer is a device that transforms AC voltage, current and impedance. When an AC current is passed through the primary coil, an AC magnetic flux is generated in the iron core (or magnetic core), which induces a voltage (or current) in the secondary coil.
Dry-type transformers are widely used in local lighting, high-rise buildings, airports, terminals, CNC machinery and other places. Simply speaking, dry-type transformers are transformers whose cores and windings are not immersed in insulating oil.
