Transposed wire is mainly used in the winding of large oil immersed power transformers,reactors and large capacity dry-type transformers.
Continuously Transposed conductors(CTC)is the important material for transformer winding.It has the advantage of well using of space, low eddy current loss, high mechanical strength and less time of coil winding.
Soft copper flat wire of enameled flat wire complies with the provisions of GB5584 2-2009 , when 20ºC , resistivity ≤0.017241Ω.mm²/m ,according to different mechanical strength requirements.
Soft aluminum flat wire of enameled flat wire complies with the provisions of GB5584.3-2009,when 20ºC,resistivity≤0.02801Ω.mm²/m.According to different insulation requirements,can choose thin film from 0.06 to 0.11mm or thick film from 0.12 to 0.17mm.The thickness of hot adhesive enameled flat wire self-adhesive layer is generally 0.03 to 0.06mm.Our company monitor the thickness with dielectric loss meter.
