Transformer aluminium strips suppliers in China

In the production of dry type transformers in Europe, America, Japan, South Korea, etc., aluminium strips have been widely used to replace copper foil or copper wire to wind low-voltage and high-voltage coil winding. The advantages of aluminium strips for transformer have been recognized and experienced by the majority of users. The product manufactured by transformer aluminum strips suppliers are used as the conductor of high and low voltage coils, which meets the requirements of miniaturization, light weight, crack resistance and aging of dry type transformers, greatly improves the technical performance parameters of the product, and improves the service life to more than 40 years.

If the copper wire is used to wind the high-voltage coil, which is bound to increase the dry volume and increase the loss. Moreover, the insulation reliability is lowered due to an increase in the voltage between the conductor layers. At the same time, due to the reduction of the electrostatic capacitance between the conductors, the ability of the high voltage coil to resist overvoltage is reduced, which affects the service life and operational safety of the dry type transformer. Because the price of aluminum is much cheaper than copper, and the density of aluminum is much smaller than that of copper, so the aluminum of the same section is much lighter than copper, but its conductivity is not much lower than copper, as long as the use of aluminum with a larger cross section, it can achieve the same or even lower power consumption than copper. The grade of aluminium strips for transformer are 1060, 1050, 1070, 1350, the temper is O(soft), the thickness is 0.2--3.0mm, the width is 20-1650mm. The surface is smooth and free of scratches, there are no burrs on the sides and can also have round edge.
