AC Insulation Performance of HDPE Mixed with EVA Applied for Power Cable Insulation
In this study, each specimen blended at weight proportions of 80％ HDPE to 20％ EVA, 70％ HDPE to 30％ EVA, 60％ HDPE to 40％ EVA, and 50％ HDPE to 50％ EVA was manufactured respectively. The insulation performances of the proposed insulator were compared with conventional XLPE, main insulating material of CV cable on the basis of the investigation results of AC insulation performances. Also, validity as an eco-friendly alternative insulating material was proved by extracting superior and inferior factor respectively. For the AC insulation performance, AC breakdown strength compared and analyzed. As it was made by blending method between thermoplastic resins, cross-linking process is not necessary. AC dielectric breakdown strength of HE64 and HE55 specimen at 90℃ was higher than other specimens. Polar groups introduced in molecular chains of blended specimen plays an important role in enhancement of thermal conductivity. It was estimated that thermal stability was improvement. Therefore waste insulator can be recycled as raw materials for uses such as jacket of low voltage insulation wire, insulation layer of medium voltage cable various products.
