Method of detecting overcoating rubber flowed in space between core member and securing metal fitting of polymer insulator |
摘要 |
<p>A method of detecting an overcoating rubber flowed in a space between a core member and a securing metal fitting of a polymer insulator having the core member, the overcoating arranged around the core member and the securing metal fitting fixed to at least one end of the core member, is disclosed. The method includes the steps of: applying a torque in a circumferential direction to the securing metal fitting, after forming the overcoating rubber but before fixing the securing metal fitting to the core member; deforming an index provided on a surface of the overcoating; and detecting whether the overcoating rubber is existent or not in the space between the securing metal member and the core member in response to a deforming extent indicated by the index. <IMAGE></p> |
