How Long Does a Wooden Utility Pole Last

Wood poles offer an opportunity for atmospheric carbon sequestration not provided by other materials. An Electric Power Research Institute study suggested that wood poles lasted 50 years. Most utilities assume that their poles provide 30 to 40 years of service life.

What is the lifespan of a utility pole?

A survey of 150 utility companies found the average service life of utility poles to range from 25 to 37 years. The most common reason for replacement being, “strength degradation from ground line decay”.

Which pole has longer life?

poles are used in 11 KV and 400/230 volt system to a large scale, apart from this, we also use PCC poles in 33KV H.T. Line. This type of poles is costlier than a wooden pole but cheaper than a steel pole. This kind of poles has a longer life, and the maintenance cost is negligible.
