aluminum flat wire for transformers

Jun 12, 2023

Aluminum flat wire for transformers is a winding wire made of electrical aluminum rod drawn or extruded by a mold of a certain specification, coated with insulating paint multiple times or coated with glass fiber. Mainly used in windings of transformers, motors, generators and various electrical equipment.

Production range： Wire thickness dimension a: 0.40-5.00 mm Conductor width dimension b: 3.00-16.00 mm The aluminum flat wire for transformers for enameled aluminum flat wire meets the requirements of GB Ting 5584.3. The resistivity at 20℃ is not more than 0.0280 0 .mm2/mo According to different electrical insulation requirements, a thin paint film of 0.08-0.11 mm or a thick paint film of 0.12-0.16mm can be used. The thickness of the self-adhesive layer of thermally bonded enameled flat wire is generally 0.03-0.05mm. Our company uses the D11 D11 screening paint process to make the curing of the paint film more perfect. If you have special requirements for the thickness of the paint film, please contact us.

According to customer requirements, glass-fiber-coated aluminum wire is evenly wrapped with 1-2 layers of non-alkali glass fibers on aluminum flat wire for transformers, and is immersed and baked with insulating paint with the required temperature resistance index and compatibility to make the glass fibers In between, the glass fiber and the conductor are bonded together. At present, the temperature resistance index of these products has three grades of 130, 155, and 180, and the insulation thickness is generally 20, 30, 40, and 50. This product is widely used in windings of transformers, electromagnets, welding machines or other similar

The glass-fiber-coated wire insulation layer has certain abrasion resistance, adhesion and flexibility, and has good thermal shock resistance and overload performance.
