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 everchanging 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!

In this symposium, attendees will hear from Nelson Bingel, the Chairman of the NESC and Chairman of the ASC O5 Wood Pole Committee.  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 and the California Public Utilities Commission on 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 Outcomes

  • Explain ANSI O5.1 wood pole manufacturing and dimension standards
  • Identify the NESC and/or GO 95 loading criteria
  • Compare all NESC requirements to all GO 95 requirements
  • Identity clearance basics
  • Discuss the process for third-party attachments
  • Compare of pole loading software programs
  • Discuss best practices for managing wood poles and the tremendous amount of related data

High Level Overview of California’s Overhead Electric Supply & Communication Line Requirements per CPUC General Order (GO) No. 95

CPUC GO No. 95, Rules for Overhead Electric Line Construction applies to all overhead electric supply and communication lines within the CPUC’s jurisdiction.  GO 95 was adopted in late 1941, superseding GO 64-A, with numerous revisions to the rules beginning in 1948 through 2016.  The latest edition became effective January 1, 2017.  This presentation will provide a high-level overview of select rules related to strength, loading, safety factors and clearances from the general provisions (Section I), requirements for all lines (Section III), and strength requirements for all classes of lines (Section IV).

Seattle City Light’s Joint Use application of IKE4 GPS and SpidaCalc Pole Loading Software

The Joint Use team of Seattle City Light found the need for additional pole loading analysis tools in order to ensure safety and reliability of its distribution system. With the use of the IKE GPS and SpidaCalc pole loading software, the team has been able to accurately model pole field conditions to ensure additional joint use attachments will not cause pole failure and that the poles are in compliance with current NESC rules.

Pacific Gas and Electric Pole Loading Database System

PG&E will to speak about our vision for the potential, high level structure of a shared pole loading system. We believe we are aligned with the ultimate 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?
