本绝缘子清洁指南的范围是记录使用各种设备和技术清洁所有类型受污染电绝缘子（不包括核、有毒和危险化学污染物）的程序。由于各种条件、实践、电气系统设计和污染可能性，本指南描述了电力系统绝缘子清洗的多种方法。在决定是否以及如何使用本指南中的信息时，必须根据具体情况考虑所有因素。

The scope of this guide for cleaning insulators is to document the procedures used for cleaning contaminated electrical insulators (excluding nuclear, toxic, and hazardous chemical contaminants), of all types, using varied equipment and techniques. Because of the great variety of conditions, practices, electrical system designs, and contamination possibilities, this guide is offered to describe a number of approaches to insulator cleaning on power systems. All factors must be considered to specific situations in deciding whether and how to use the information in this guide.
