Your online resource for preservative-treated wood utility poles in North America

Exciting new Powerline 2022 Overhead Conference set for Oct. 12

PowerlineThanks to a new partnership, utilities can now register to explore the newest developments in overhead wood pole systems at the Powerline 2022 Overhead Conference Oct. 12 in Overland Park, Kan.

The North American Wood Pole Council is partnering Endeavor Business Media to host the conference, which will held just before the International Lineman's Rodeo & Expo Oct. 13-15. Endeavor manages the lineman event and publishes T&D World and Utility Products magazines and websites.

The conference will feature a special panel of wood pole preservative manufacturers. Other presentations include a new look at sustainable design with wood poles for resiliency, wood pole quality control for utilities, BIL lightning strategies, national standards for wood poles and the performance of pole remediation treatments.

Powerline 2022 is intended for utility personnel who are involved with design, purchasing, installation, management and maintenance of the electrical distribution and transmission systems.

Register for Powerline 2022 and review the full conference agenda online. Sponsorship opportunities for the conference also are available on the site.

New guides released on today's wood pole preservatives

With the retirement of a preservative used for wood utility poles, there are two new guides available to help utilities review and select other preservatives used to protect poles from decay fungi and insects.

Preservative guides

The new Technical Bulletin Preservative Options for Wood Utility Poles reviews the commonly available preservatives used today It further details the process each preservative must go through to be approved for use in making durable, long-lasting utility poles. The eight-page bulletin provides a table of the retentions, or amount of preservative, for each species and respective Use Category that poles can be treated to, based on the conditions where they will be used.

There are six preservatives used today, depending on the species and region. Pentachlorophenol or penta, is no longer being produced, but many treaters have enough of the preservative in stock to treat poles for many more years. Eventually, treaters and utilities will transition to other preservatives listed in the guides.

A shorter, two-page guide Pole Principles - Preservatives for Wood Utility Poles offers an overview of the pole preservatives. Under each preservative is the species commonly treated and the companies that manufacturer the preservatives, including links to the manufacturer's website for additional information.

Check out the new guides in the Technical Library.

Sustainable alternatives explored for overhead resiliency

SustainBigger may not be better -- nor sustainable -- when it comes to increasing wood pole sizes to improve overhead system resiliency. The new Technical Bulletin Sustainable Wood Pole Design for Overhead Systems explores practical alternatives to specifying larger poles.

Utilities should incorporate sustainable forestry into resiliency efforts and can do so by utilizing more readily available pole classes with spans between closer together.

The 12-page bulletin explores the natural growth of trees and its importance in creating larger poles, which are often more expensive due to limited availability. An alternative to specifying bigger poles is to move poles closer together, which enhances reliability while balancing what pole sizes are available in today's renewable forests.

Detailed examples are offered showing how to meet NESC requirements with shorter spans, as well as cost considerations. Take a look at this environmentally responsible alternative to keep electric lines up and working.

Carbon calculator highlights wood pole, crossarm benefits

Utilities eager to tell customers about their commitment to the environment now have a new tool that quantifies the green benefits of preservative-treated wood poles and crossarms.

CarbonCalcThe Technical Bulletin Calculating Carbon in Wood Utility Poles and Crossarms details how to calculate the amount of carbon sequestered in a utility's inventory of wood utility poles and crossarms. The calculations take into account of the volume and mass of the wood, as well as the mass of carbon dioxide removed from the atmosphere while the wood is in service.

The Wood Utility Pole & Crossarm Calculator is available in an online version or as a downloadable Excel-based calculator. It calculates the volume and mass of the wood, as well as the mass of carbon dioxide removed from the atmosphere for a utility's inventory of wood utility poles and crossarms.

The calculator allows utilities to determine the amount of carbon residing in their inventory of poles and crossarms. The number of utility poles can be entered using pull-down selections for the class and length based on the standard ANSI pole sizes. Crossarm data is entered by its actual dimensions. Up to 30 different sizes of poles can be entered.

The calculator automatically determines the total volume and mass of the wood, the mass of carbon in Imperial and metric tons and the mass of carbon dioxide removed by using wood. The data can be entered into the online EPA Greenhouse Gas Equivalencies Calculator that can convert carbon data into real world examples of the environmental benefits, such as miles driven by an automobile or barrels of oil consumed.

New video series explains national wood pole standards

NtlStd-1A detailed overview of the national standards that guide the design and use of wood utility poles is now available in a special three-part video series.

The National Wood Pole Standards video series is an expanded version the most downloaded technical document on the website. Commentary is provided by Nelson Bingel, chair of the ASC O5 Committee, which oversees pole standards. Bingel also chairs the National Electrical Safety Code (NESC).

Each video is between 16 and 19 minutes long. Part 1 reviews the standards guiding the production and use of wood utility poles, the scope of those standards and the unique strengths and loading for wood poles. Part 2 discusses wood pole species, applied loads, pole circumferences, and groundline and height stresses. Part 3 reviews the NESC, grades of construction, transverse loading and other design factors.

The videos can be played in preview window on your computer. There are also links to view the videos on YouTube.

Energize your community outreach with customized coloring book

ColorBookUtilities can get an assist in expanding their community affairs activities and communicating important safety information on overhead lines with a special low-cost, customized coloring book.

The 16-page book Electricity from Tree to Me is designed for children from kindergarten through elementary school. It explains how wood utility poles are made from sustainable and renewable trees and includes important safety messages for about overhead lines, including what to do if lines are on the ground.

The book is designed to be customized with utility information on the inside cover page and the back cover. The pages can feature colored artwork, such as a utility or company logo, so it can be integrated into utility community affairs programs.

Utility specific coloring books can be ordered for about $1 each for 1,000 copies or more. Quantities of 500 and 750 are also available at a discounted price.

Benefits of wood crossarms detailed

For as long as there have been wood poles, there have been wood crossarms. The often overlooked benefits of wood crossarms compared to alternative materials our outlined in a new publication Wood Crossarms: Six Overlooked Benefits from a Century of Performance.

The one-page technical sheet reviews the extensive performance record of wood crossarms, which can be found throughout North America. Wood crossarms are a vital component that carry wires and other equipment to bring electricity to the continent.

Common misperceptions, such as wood crossarms are heavier, are explored in the sheet. It also notes that alternative materials are often three to four times more expensive than wood for crossarms that are functionally equivalent.
