Advantages

Squarelike coils feature minimal gaps and exhibit superior heat dissipation compared to round wire coils of the same size. With a small radius and high slot fill factor, these coils reduce DCR by 15-20%, enabling higher current capacity, increased power output, and reduced heat generation.

Enameled flat wire with a large width-to-thickness ratio

Wellascent is capable of producing enameled flat wires with a large width-to-thickness ratio of up to 30:1. While achieving this high ratio, we ensure uniform enamel coating on the wire sides and consistent insulation thickness across the entire cross-section.

Special-Shaped Copper Wire

The special-shaped rectangular copper wire can increase the area of conductor in limited size or space.

lt is mainly used for magnetic ring inductance and motor products.

Advantages

► More inductances are obtained with the same core design than with round wires.
► Higher space factor, reduce temperature rise.
