PREFACE

The purpose of this manual is to provide the reader with a basic knowledge of the principles and methods for the design and use of wood poles for overhead utility line structures. This manual is the result of a multiyear collaborative effort by engineers and technical experts from electric utilities, consulting rms, academia, and manufacturers engaged in the design and application of these structures.

Every effort has been made to ensure the accuracy and clarity of this document. The user is reminded that utility line structures are an integral part of a larger overhead line system and therefore cautioned that the application of these structures should come only after sound engineering judgment has been applied. Furthermore, as an overall treatise covering a wide variety of line applications, this document cannot conceivably satisfy all conditions. The user should bear in mind that often there will be specic local conditions and requirements that may dictate design and usage conditions that differ from those described herein.

The task committee is grateful for the dedicated effort of all who participated in the development of this manual.
