Wood Pole Overhead Lines
Wood Pole Overhead Lines provides comprehensive coverage of medium voltage wood pole overhead lines. It includes guidance on the planning and mechanical design of overhead lines, as well as details of statutory requirements and the latest UK and European standards affecting UK design of wood pole networks, Sag/tension calculations are explained, and details of the latest work on safe design tension limits to avoid conductor fatigue from vibration are included. The basic characteristics of bare and covered conductors are discussed as well as upgrading possibilities, condition assessment and the latest work on 'health indices' for overhead lines. Other topics include wood pole decay and mitigation methods, maintenance schedules, live line working and basic lightning protection.
What people are saying - Write a review
The section of this book which deals with wayleaves is seriously flawed and contains information that is not correct. In fact, if followed, the advice would mislead.
An electrical engineer is as familiar with wayleave matters as a Wayleave Officer is with electrical engineering, but you would not see a Wayleave Officer including technical advice in a book about wayleaves.
If anyone requires professional wayleave advice they should contact the RICS (Royal Institution of Chartered Surveyors). Do NOT take advice from anyone that is not RICS accredited.
