aluminium strip
What are the processing and production steps of aluminium strip?How to produce aluminum strip for transformer winding?
Demand for aluminum foil using for aluminum coil for transformer is new and will be more.
Aluminium strip/ foil for transformer are made of high quality pure Aluminium. They are soft with high conductivity, flat surface, smooth edge and no burr. They are the key raw materials for making Transformer winding. Using qualified Aluminium strip, Transformer has the advantages such as miniature and light weight, nice insulation performance, anti-flaming, no pollution, small partial discharge, moisture resistant, stable operation, low noise & low maintenance cost etc.
Transformers are designed and built with copper or aluminium windings. But transformers using aluminum foil winding have advantage of small size, light weight, good insulation properties, flame retardant, non-polluting, partial discharge, resistant to moisture, smooth and reliable operation, low noise, and low maintenance cost.

ype transformers, aluminium–aluminium windings have been commonly used nowday. Aluminium foil strip can replace copper conductors in distribution transformers. Aluminum foil and sheet in appropriate strip widths and lengths have widely replaced wire in electrical transformers.
The aluminium strip 25mm x 3mm 1mm 2mm 5mm 10mm 50mm production process:
First step:raw material slitting
Aluminum foil raw material with Slitting equipment made into the width customers needs
Second:Aluminum foil winding
In order t0 ensure the quality of aluminum foil,the side treatment is made on the equipment
Third,Aluminum foil fixed
The detection width and thickness deviation of the aluminum foil are in line with the technical requipments of the customer,Add a paper sleeve to the scrolls and fix aluminum foil with glass fiber tape
