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. The purpose of this guide is to present information on the equipment needed and the methods that can be used when cleaning contaminated insulators. The methods or equipment, or both, presented in this guide are not intended to prescribe specific procedures, but to present the successful experience of many individuals who have safely cleaned contaminated insulators. The guide is intended to serve as a reference source for a company, or persons, seeking information on insulator cleaning procedures so that they may consider the experience of others in modifying or formulating insulator cleaning programs and practices. Revision Standard - Inactive-Reserved. Procedures for cleaning contaminated electrical insulators (excluding nuclear, toxic, and hazardous chemical contaminants) of all types, using various equipment and techniques, are provided.
