Abstract
A polymer insulator having a core member, an insulation overcoat member arranged on an outer surface of the core member, and a securing metal fitting fixed to an end portion of the core member in such a manner that the end portion is contacted with the insulation overcoat member is disclosed. The disclosed polymer insulator further includes a seal portion arranged at a boundary between the insulation overcoat member and the securing metal fitting, which is made of a sealing agent in which 80-250 parts by weight of ATH (Alumina trihydrate, Al.sub.2 O.sub.3.3H.sub.2 O) is included with respect to 100 parts by weight of a polymer component. Therefore, the polymer insulator according to the invention has an improved tracking-erosion resistance performance.
