Aluminum strip for transformer winding price

Author: Nydia View: Time: 2018-10-12 15:08

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 aluminum strip for transformer winding price is lower than copper foil price, so, the aluminum strips occupy more market in transformer enterprises.

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 aluminum strip for transformer winding 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 aluminum strip for transformer winding price 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.
