Aluminum foil winding in transformer

Dec 11, 2021

Aluminum foil winding in transformer is mainly used for the internal winding of dry-type transformers. It is generally made of pure aluminum. The edges are cut without burrs and the finished surface is smooth and traceless. The plate shape is flat, and the section is neat and round after chamfering. Angle, zero glitch.

In addition, it is required that the section of the aluminum foil is neat, rounded, and free of burrs, loose rolls, risers, towers and other defects.
Surface quality: Aluminum foil winding in transformer surface has no defects such as roll marks, black lines, bright spots, scratches, bumps, etc., and no oil spots, tears, blisters, etc. formed after annealing.
Packing:

　　 has large roll packaging and wooden box packaging.
　　Large roll packaging: The size of the large roll is determined according to the width, thickness, roll diameter and length of the large roll.
　　 Wooden box packaging: The size of the wooden box is determined by the length, thickness, width and single box weight customized by the customer.
