Applications
Composite conductors are primarily used in windings of oil-immersed transformers, reactors, and other electrical equipment, especially suitable for: Large power transformer windings: Meets the requirements for long continuous winding, enhancing overall winding performance. Reactor windings: Compact structure and neat arrangement, ideal for reactor designs requiring high inductance and low losses. High-reliability electrical equipment: Suitable for applications with strict requirements for electrical insulation and mechanical strength. Customized winding structures: Flexible arrangement and insulation material options based on electrical and structural needs. High power density equipment: Ideal for winding designs with limited space but high current-carrying capacity requirements.
Exclusive Advantages
Ultra-long continuous manufacturing for improved winding efficiency: Single conductor length exceeds 8,000 meters without joints, significantly reducing winding joints and improving manufacturing efficiency and reliability.
Wide range of arrangement options for strong adaptability: Supports axial stacked, axial aligned, radial aligned, and combined arrangements to meet various electrical and spatial layout requirements.
Multiple insulation material options for design flexibility: Available in paper-wrapped, enameled, and film-wrapped versions to suit different insulation grades and environmental conditions.
Broad cross-section range for greater design freedom: Flat wire thickness from 1.00 to 12.00 mm, width from 3.00 to 25.00 mm, width-to-thickness ratio ≤20, and maximum cross-section up to 200 mm², covering most mainstream winding design needs.
Compact structure with excellent electrical performance: Tightly arranged and evenly wrapped conductors ensure optimal electric field distribution and mechanical strength, enhancing equipment operational stability.
