Rectangular-section bare conductors made from high-purity oxygen-free copper, with no insulation layer, exhibit outstanding electrical conductivity, thermal conductivity, and mechanical strength. Available in thicknesses ranging from 0.8 to 12 mm and widths from 3 to 25 mm, these conductors can be custom-configured as multi-wire assemblies. They serve as the core base material for enameled, paper-insulated, and other types of insulated conductors and are widely used in transformers, reactors, motor windings, busbars, and other applications.

Bare copper flat wire

Copper conductors are coated with insulating varnishes such as polyester, polyester-imide, and polyamide-imide to form a thin, dense insulation layer. These coatings offer excellent electrical insulation, heat resistance (Class B–220), flexibility, and scratch resistance, making them well suited for high-speed winding applications. Available in round and flat forms, they are the mainstream choice for motor, transformer, and appliance windings, serving a wide range of applications including household appliances, industrial equipment, and general electrical systems.

Product categories

Enameled winding wire

It is constructed by regularly transposing and insulatingly wrapping multiple (5–87) enameled rectangular wires, effectively reducing the skin effect and load losses while enhancing winding heat dissipation and mechanical strength. With a compact structure and high winding efficiency, this design is specifically tailored for high-power equipment such as large power transformers, traction transformers, and reactors, significantly lowering temperature rise and improving operational stability.

Product categories

Transposition conductor

Bare copper flat wire is uniformly wrapped with electrical insulating paper (such as cable paper and NOMEX paper), resulting in a uniform insulation layer that exhibits excellent heat resistance, oil resistance, and high mechanical strength. It is well-suited for oil-immersed environments, offering stable insulation performance and available in a full range of specifications. As the traditional preferred material for windings in oil-immersed power transformers, instrument transformers, and reactors, it ensures long-term reliable operation.

Product categories

Paper-impregnated winding wire

Rectangular-section enameled wire specially designed for drive motors, inverters, and on-board motors in new-energy vehicles. It features a high-temperature, corona-resistant, and refrigerant-compatible insulation system, achieving a slot-fill factor 15–30% higher than round wire, thereby reducing resistance and losses while enhancing power density and thermal dissipation efficiency. The product meets automotive-grade reliability standards, is compatible with 800V high-voltage platforms, and supports efficient, lightweight, and long-life motor operation.
