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 heat-shrinkable creepage extenders on the principleof heat-shrinkable high polymer. A comparision of main properties between a similarly typical product andours 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 thefunction of resisting flash and anti-griminess.
