Aluminium foil/strip with round edge and without burr
Aluminium strip/ foil with round edge and without burr used 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/foil, 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.
