热收缩型爬距增长器的研制

The Formulating and Processing of Heatshrinkable Creepage Extenders

本文从热收缩型爬距增长器的设计原理出发 ,分析讨论了材料性能要求 ,配方研制和辐照工艺要点 ,并将所研制产品的主要性能指标与同类产品的典型指标进行了比较。试验表明 :安装热收缩型爬距增长器 ,可使立柱绝缘子的爬电距离增加 16 %～ 32 % ,污闪电压提高 15 %～ 33% ,同时还具有明显的阻弧、防污作用。

This paper studies the formula and process of heatshrinkable creepage extenders on the principle of heatshrinkable high polymer.A comparision of main properties between a similarly typical product and ours was made.The test result shows that the creepage extender installed on a support-insulator can increase the creepage up to 16%~32% and the flash voltage up to 15%~33%,which have remarkably the function of resisting flash and anti-griminess.
