Aluminum strip transformer windings are suitable for low voltage (hundreds of volts), high current (hundred amps to thousands of amps) transformer, and are commonly used as secondary windings for distribution transformers. The foil type transformer adopts high conductivity copper foil strip or
aluminum strip as the conductive material, and the thickness of the copper foil or
aluminum strip foil is about 0.1 to 2.5 mm. The <strong>
aluminum strip for transformer winding price</strong> is lower than copper foil price, so, the
aluminum strips occupy more market in transformer enterprises.<br></p>

We all know that, the conductivity of copper foil is higher of
aluminum foil, but why more and more customers prefer
aluminum foil strips than copper foil is not just because of saving coat. Moreover, for the dry type transformer, since the thermal expansion and contraction coefficient of aluminum is closer to the thermal expansion and contraction coefficient of the epoxy resin than the copper, the crack resistance of the <strong>
aluminum strip for transformer winding</strong> is better than that of the copper. Moreover, since the strength of the dry transformer winding itself is very good, the difference in mechanical strength between copper and aluminum has no practical significance. Due to using the 1000 series aluminum, the <strong>
aluminum strip for transformer winding price</strong> on the market is not high, 1060 and 1070
aluminum strips with round edge and no burr are good choice to processing dry type transformer winding.</p>
