Aug 11, 2020.Dry type transformers typically feature either copper or aluminum windings, also known as coils. Transformer windings refer to the coils within the transformer that draw and distribute power inside the unit. There are typically two windings in a dry type transformer one that draws power from the source and another that transfers that power to the load.

Windings are found mostly in relay coils, small transformers, Ignition coils, small electrical motors, and generally devices with relatively small wire gauges up to 0.05 mm. Achieved fill factors with the use of round wires are about 73% to 80% and are lower compared to Orthocyclic windings with a 90% fill factor.
In North America, aluminum is the predominant choice of winding material for low-voltage, dry-type transformers larger than 15 kilovolt-amperes (kVA). In most other areas of the world, copper is the predominant winding material. The primary reason for choosing aluminum windings is its lower initial cost.
Finally, annealing, winding and packaging, annealing is in the constant temperature of the annealing furnace for a period of time, through the high temperature change the internal grain size of the aluminium coil strip to obtain a variety of mechanical properties and elongation, and then after annealing, the need to reel through the winding
Oct 14, 2021.In the production process, the aluminum sheet and strip go from ingot to hot-rolled coil and then to the cold-rolled coil. Accordingly, it will be rolled and processed by different equipment, such as hot rolling mill, cold rolling mill, rewinding, annealing, shearing and bending, and straightening. The manufacturer needs to have strict production implementation guidelines
Jan 08, 2020.An aluminum coil produced using high-pressure die casting with seven windings and a conductor height of approx. 1.5 mm. A study has now shown that aluminium coils increase the continuous output of electrical machines compared to copper windings, reduce the operating temperature and at the same time save weight and raw material costs.
Jan 26, 2021.The cost of the aluminium coil is very low. Hence, it reduces the overall cost of the transformer. This type of winding can be rolled to thinner and more flexible than copper. Aluminium foil windings are best suitable for low and medium rated voltage transformer from (11 kV to 33 kV). Aluminium foil winding act as a good insulator against heat.
Jan 18, 2001.This means windings wound with aluminum wire will likely have greater volume compared with an equivalent copper wire motor. The second consideration is properly connecting the ends of the aluminum magnet wire. The reason for this goes back to your high school chemistry course.

Jan 18, 2001.Conductivity and Connections. First, aluminum conductivity is lower than copper. To compensate, aluminum magnet wire must have larger cross-sections than the equivalent copper wire to offer the same conductance. This means windings wound with aluminum wire will likely have greater volume compared with an equivalent copper wire motor.
