Custom Rectangular Enameled Wire
Custom Rectangular Enameled Wire Overview Rectangular copper wire has specific requirements for the R-angle size. It is a special-shaped enamelled wire extended from flat wire, composed of a rectangular conductor (copper, copper alloy, and other materials) and an insulating coat. A bonding coat can also be compounded on the surface of the insulating coat to achieve self-adhesive effect. The R-angle size of flat wires is typically half of the thickness, while rectangular wires
Rectangular copper wire has specific requirements for the R-angle size. It is a special-shaped enamelled wire extended from flat wire, composed of a rectangular conductor (copper, copper alloy, and other materials) and an insulating coat. A bonding coat can also be compounded on the surface of the insulating coat to achieve self-adhesive effect.
The R-angle size of flat wires is typically half of the thickness, while rectangular wires can be manufactured with smaller R-angle sizes according to specific application requirements. This requires more precise workmanship and presents greater production challenges compared to flat wire.
- Compared with traditional round wires, rectangular wires provide larger surface area and superior heat dissipation performance when cross-sectional area is identical
- Rectangular wires offer significant advantage in copper space factor. Under the same space constraints, compared with round and flat wires, rectangular wire achieves the highest copper space factor due to their smaller R angle advantage
- Compared with round wires, rectangular wires can reduce wire DCR by 15–20%, significantly improving the electrical performance of coils
