Transformer aluminium strip suppliers on the market

Transformer aluminium strip suppliers occupy more proportion on the market for dry type transformer winding strip. The dry type transformers which all the winding of high and low voltage winding are made of aluminum strips has the advantages of fire proof, flame retardant and pollution-free. 1060, 1050, 1070 and 1350 aluminum can be used as the transformer aluminum strip, the 1060 O aluminum strip are common used.
 
Compared with copper wingding, aluminum strip transformer winding also have the following characteristics.
1. the thermal expansion coefficient of aluminum strips is closer to epoxy than copper and can prevent cracking completely.
2. the aluminum strip coil has large linear capacitance, good impact resistance and uniform distribution of impact voltage gradient, which can effectively suppress potential fluctuations.
3. the transformer aluminum strip coil is light in weight, and under the same resistance value, the aluminum strip coil is only half the weight of the copper strip coil.
4. the special aluminum strip for transformer is used. The aluminum strip has enhanced mechanical strength, high electrical conductivity, and the surface is bright, and it is not easy to oxidize.
5. welding is strong and reliable, low contact resistance, no local heating, and increase the overload capacity of the transformer.
