The standard utility pole in the United States is about 40 ft (12 m) long and is buried about 6 ft (2 m) in the ground. However, poles can reach heights of 120 ft (37 m) or more to satisfy clearance requirements.The average life expectancy for a wood pole varies, depending on location, from 30 to 40 years. This useful life of a pole may be shortened due to several factors. One of the most common problems associated with wood utility poles is decay of the wood. New poles receive a preservative treatment to help prevent decay. lifespan of telephone pole
Interestingly, most utility companies estimate the serviceable life span of a pole to be only 35 years. Wood Utility Pole Treatments. Utility poles are usually treated with either pentachlorophenol, chromated copper arsenate, copper napthenate, or creosote.
The pole inspection data collected by power utilities under conventional practices provide limited and indirect information about the pole survival rates. The paper therefore presents advanced statistical methods to analyze inspection data for the estimation of pole life expectancy (LE) and lifetime distribution. Maintenance is also a major factor in pole service life. A 2012 Quanta Technology study on wood pole service life calculated the average expected lifetime of a wood utility pole with an inspection and treatment program at 96 years. Osmose Utilities Services reviewed data on 751, 000 utility poles inspected across the U. S. between 1988 andlifespan of telephone pole Of these, approximately 87, 000 about 27 of the DWP utility poles have exceeded their 60year lifespan, according to an article in the Los Angeles Daily News, DWP lagging behind on replacing old power poles.
The poles are then transported from the pole yards to the utility company that will put it up, and, from there, the utility company trucks the pole to its final destination. At the final destination, line beds andor cranes are used to lift and set the poles into the ground. lifespan of telephone pole POLES Several utility industry surveys have been conducted in the last 15 years seeking information on n Vanous materials used in the construction of transmission Of and poles is WOOD POLE LIFE SPAN: WHAT YOU CAN EXPECT By H E CO These are questions that should be How can the answer be improved?
