In the electrical industry, motors, generators and transformers use rectangular wires with a prescribed corner radius, that is, Rectangular Enameled Copper Wires.
Compared with the round wire, the rectangular wire has the advantage that the winding is more compact, which saves space and reduces weight. Electrical efficiency is also higher, thus saving energy.
Especially when the wire is to be insulated with enamel, the accuracy of the width and thickness and the geometry of the corner radius are crucial for the defect-free use of the electrical coil.
The application fields of rectangular enameled copper wire are:
Suitable for AC and DC motors and generators from 200 to 240
AC motor driven by inverter
Electromagnetic coil and conductor coil withstand voltage peak
Electric motors and generators for the aviation and marine industries
Refractory motor for tunnel ventilation
Motors and equipment in the nuclear field
Oil-immersed and dry-type transformers
