受污染的聚合物绝缘子的柄部区域容易受到局部电弧的热损坏。为了缓解这个问题，最近已经提出用规则的突起图案塑造聚合物表面的轮廓，以降低这些区域中的漏电流密度和电场强度，并通过相同的方式实现爬电长度的增加。描述了用各种类型的纹理图案和一系列尺寸的半球形突起制备的样品的斜面测试性能，以及用于比较的非纹理平面样品的结果。通过这种纹理化，在满足标准测试标准、限制表面放电活动以及减少样品的漏电起痕和侵蚀方面取得了显着的改进。
The shank regions of a polluted polymeric insulator are vulnerable to thermal damage from partial arcs. To alleviate this problem, it has recently been proposed to contour the polymeric surface with regular patterns of protuberances in order to reduce both the leakage current density and electric field strength in such regions, and by the same means to achieve an increase in creepage length. The performance in inclined-plane tests of samples prepared with various types of textured pattern, and a range of sizes of hemispherical protuberances, are described, along with results for non-textured plane-surface samples for comparison. A remarkable improvement is achieved by such texturing in the satisfaction of the standard test criteria, and in limiting surface discharge activity and reducing the tracking and erosion of the sample.
