What are the electromagnetic wire for transformers?
- Nov 07, 2018 -

Commonly used materials for winding transformers: enameled wire, yarn wrapped wire, wire wrapped wire, paper covered wire, the most commonly used enameled wire. For the requirements of the wire, the conductive property is good, the insulating paint layer has sufficient heat resistance, and has a certain corrosion resistance. In general, it is best to use the Q2 model of high-strength polyester enamel.

The main components of the transformer are the iron core and the coil, and the others are accessories.

Core material: The core material used in the transformer mainly includes iron piece, low silicon piece and high silicon piece.

Insulating material: In the wound transformer, the insulation between the coil frame layers and the isolation between the windings are all made of insulating materials. The general transformer frame material can be made of phenolic paperboard, epoxy board and cardboard.

Impregnating material: After the transformer is wound, the last process is to dip the insulating varnish, which can enhance the mechanical strength of the transformer, improve the insulation performance and prolong the service life. Under normal circumstances, cresol varnish can be used as the impregnating material or 1032 insulating varnish, resin lacquer.
