Thin metallic wire is widely used in electrical, electronic and automobile technology. It is, however, necessary to anneal and clean the copper wire after drawing. The traditional manufacturing process of fine wire consists of three processes: drawing, annealing and cleaning as shown in Figure 1 and 2 [1]. These processes use Joule heating and chemicals to anneal and clean the wire [2-4]. However, this method has some drawbacks: low efficiency due to the division of the annealing and cleaning processes and environmentally harmful because of using chemical to clean thin wire, for example, Tri-chloethane, it is hazardous to human body and has ozone layer effect. The new annealing system in which the annealing and cleaning processes are simultaneously operated in Atmospheric Pressure Dielectric-Barrier Discharge (APDBD) [5-9] is the potential solution for these drawbacks. In previous studied, it is shown that wire annealing [10, 11] and cleaning [12] using APDBD is totally possible. Also, our previous studies showed that annealing using APDBD is possible for thin copper wire [13], [14] however; the annealing efficiency is low due to choosing the material, size and shape of the dielectric, discharge gas, applied power,... In this study, the efficiency of dielectric material on the annealing and cleaning results was investigated. It is, however, the dielectric material and the dielectric size are the first two important parameters need to be investigated. Moreover, the efficiency of the frequency and the applied voltage of the applied power in the dielectric permittivity were also investigated. To clarify these dependences, an equivalent circuit model is used to analyze the effect of dielectric.
