pew square section copper winding wire also called pew square section cu winding wire is one of Coil Winding Wire, square winding method reaches the highest fill factor and is the best way to fill the available winding cross-section with round wires. 

What is the fill factor of a winding?
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.

What is square magnet wire wire?
Square magnet wire wire is useful where space constraints are concerned. When formed into a coil an equivalent amount of square wire put in a coil can be placed in a tighter coil configuration than the same amount of round wire. This enables engineers to create compact coils and small motors that deliver more power in less space.

What is a coil winding wire coil?
Coil Winding Wire Coils provide the magnetic field of motors, transformers, and generators, and are used in the manufacturing of loudspeakers and microphones. The shape and dimension of the wire used in a coil winding are designed to fulfill a specific purpose.
