ZZB Oil-immersed Transformer Reactor And Other Electric Devices Composite Wire

Composite wire is a winding wire composite of several winding wires or copper and aluminum wires arranged in specified requirements, wrapped by specific insulating materials.Composite wire is mainly used in windings of oil-immersed transformer, reactor and other electric devices.

Hengte Electric is a professional manufacture of copper, aluminum paper covered wire, composite wire. Products are precise in size and shape, suitable in wrapping tightness; their continuous no-joint length is more than 8, 000 meters.

    Product Scope and Technical Specifications

    Our company specializes in the production of high-performance composite conductors, offering a full range of options including bare flat composite wire, paper-covered composite wire, enameled composite wire, and film-wrapped composite wire. These products are designed for reliable electrical performance, excellent insulation, and mechanical stability, making them suitable for use in transformers, motors, reactors, and other electrical equipment.

    Production Scope and Size Range

    We provide flat wire conductors with thicknesses ranging from 1.00 mm to 12.00 mm and widths from 3.00 mm to 25.00 mm, with a width-to-thickness ratio ≤ 20 and a maximum cross-section of 200 mm². For round wire conductors, the available diameters range from 2.00 mm to 5.00 mm, meeting the needs of various custom designs and insulation structures.

    For enameled paper-covered wire and enameled composite wire conductors, we recommend flat conductor sizes between 1.00–3.00 mm in thickness and 5.00–18.00 mm in width, while round conductors are available from 2.00–5.00 mm in diameter.

    In addition, our bare wire, paper-wrapped, and film-wrapped composite conductors are manufactured with thicknesses from 1.00 mm to 6.00 mm, widths from 4.00 mm to 20.00 mm, a width-to-thickness ratio ≤ 20, and a maximum cross-section of 150 mm².

    All our wires are produced under strict quality control with smooth surface finish, precise dimension tolerance, and uniform insulation coating. We are capable of customizing conductor dimensions, insulation materials, and packaging types according to customer specifications, ensuring stable performance and long service life in demanding electrical and electronic applications.
