Paperback. Condition: New. Print on Demand. This book by the author investigates the causes of why electricity poles twist as they are subjected to the effects of weather conditions and other environmental pressures they face in service. The author's research underlines that the lesser-known growth patterns of trees and their spiral grain characteristics are the principal cause of such twisting. The book highlights how the study of forestry can have a real-world impact on the industries involved with the cultivation and use of wood. It examines the difficulties faced by pole producers in identifying the grain of unpeeled poles and the problems faced by pole users when a pole distorts or breaks while carrying electricity. By providing insights into the causes of this twisting, the book can help improve the ability to select suitable poles, improving the stability of existing electrical infrastructure and contributing to the safe and efficient delivery of electricity.
