Overview

When it comes to wood utility pole strength and loading, the experts say, “know the code!”, the National Electric Safety Code or California’s General Order 95 that is. In the ever changing world of electric utility and telecommunication companies, knowing the codes, regulations, and best practices, is vital to not only keeping the power on, but to ensure the safety of linemen and the public. With the advent of 5G on the horizon, telecommunication and wireless companies are eager to attach additional equipment to utility poles, thus making it more important than ever for electric utility and telecommunication companies to know and follow the codes!

Pole strength capacities will be explained along with the loading criteria of the NESC and GO 95. An overview along with hands-on examples of basic pole loading calculations will help with understanding the important aspects and variables that impact how a pole is loaded. Variations of the third-party attachment processes around the country will be briefly explained and followed with an emphasis on the importance of wire and equipment clearances and the make ready process. Managing wood pole data including strength and loading details will also be discussed.

This symposium will include case studies from electric utility and telecommunication companies including their experiences with pole strength and loading, various software programs, and “best practices”. The goal of this program is to not only educate the attendees on the topic, but to also facilitate a discussion amongst the group to share their insights.

Learning Objectives

  • Explain ANSI O5.1 wood pole manufacturing and dimension standards
  • In-depth review of NESC strength and loading criteria along with an overview of GO 95 criteria
  • Comparisons of key NESC requirements to similar GO 95 requirements
  • Identify clearance basics
  • Discuss the process for third-party attachments
  • Comparisons of pole loading software programs
  • Discuss best practices for managing wood poles and the tremendous amount of related data
  • Discuss best practices for adding attachments to existing poles

Pole Loading and Pole Remediation Programs

A variety of inspection and in-service treatments are performed on wooden utility poles to ensure a strong and safe wood pole plant. Good inspection data is critical to any strength rating calculation and the aluminum inspection tag that is placed on the pole tells the basic history of what has, or has not, been done to qualify that pole as sound.  

This presentation will explore each of the currently available inspection techniques and uncover the ground-line area defects in wood poles that these inspections are designed to identify.  After inspection, a number of remedial wood preservative treatments are available to prolong the life of this valuable asset.   A summary of these treatments will inform the audience of their uses and benefits.  Finally, inspections can identify poles that might benefit from in-service reinforcement techniques.  The most common reinforcements will be reviewed.

CASE STUDY: Pacific Gas and Electric Pole Loading Database System

PG&E will speak about our vision for the potential, high level structure of a shared pole loading system. We believe we are aligned with the goal of the CPUC for a statewide pole and conduit

database. Our demonstration will use conceptual images and discussion to convey three points: (1) How could we give our end users and business partners self-service access to information about available pole capacity? (2) How would a view of available capacity transition to an electronic application or request to attach? (3) How could a user be profiled to be given visibility into a list of historical submissions and their statuses?

Clearance Basics

  • Vertical clearances over surfaces
  • Clearances between wires on different supporting structures
  • Clearances of wires from buildings, bridges, swimming pools, and others
  • Clearances for wires carried on the same structure
  • Climbing Space
  • Working Space
  • Edition of the Code
