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.
Conductor material: oxygen-free copper; temperature rating: 220°C
Conductor material: oxygen-free copper; temperature rating: 240°C
Conductor material: oxygen-free copper; temperature rating: 240°C
To achieve this, a specified number of acetal-insulated copper flat wires are arranged in two parallel columns with their wide faces in mutual contact. On the upper and lower surfaces of these two columns, the wires are transposed in the same direction along their narrow faces, and the winding is then tightly and continuously wrapped in multiple layers using electrical insulating paper tape.
A bundled transposed conductor consists of two transposed conductors arranged in axial parallel alignment, collectively enclosed by a specified insulation.
A special type of bundled transposed conductor in which pre-stranded transposed conductors are arranged in parallel and then formed into a stepped configuration.
The internally shielded transposed conductor consists of two transposed conductors arranged in parallel, with multiple shielding wires vertically positioned between them in a narrow-face contact configuration, all collectively enclosed by a common insulating sheath.
It refers to a winding wire formed by arranging a specified number of ultra-thin enameled copper flat wires into two parallel columns with their wide faces in mutual contact, performing turn-to-turn transposition on the narrow faces of both columns in the same direction as required, and inserting insulating paper of a specified thickness between the two columns. The entire assembly is then continuously wrapped with electrical insulation paper, tape, or mesh band to form the final winding.
To enhance the local electrical insulation of the windings at specific locations—such as the top, bottom, and sides of the interposed lead wires—insulating paper is inserted; heat dissipation is then accomplished through the remaining surfaces where no insulating paper is applied.
Paper-covered copper flat wire is a type of winding wire in which multiple layers of insulating paper tape are continuously wrapped around the surface of a copper flat wire.
It is a winding wire composed of multiple paper-insulated copper flat wires or enamel-coated copper flat wires arranged radially along the winding, with multi-layer continuous insulation wrapping using insulating paper.
