Utility Wood Pole Inspections and Supplemental Treatment

Experienced and accredited inspectors inspect utility poles to identify unserviceable poles in an electrical power system. Wood poles are damaged by lightning, attacked by fungi and termites, or may crack and become dangerous over time.

The poles are graded according to the level of the damage or decay and in line with the utility’s standards. Supplemental treatment is applied where and when required to eliminate or minimize attack by natural elements. Information is captured electronically in a database with GPS co-ordinates to use in GIS systems. The data is processed and analyzed for easy interpretation by the client. Wood Pole Inspections is a preventative maintenance procedure adopted by Eskom and other utilities, to identify poles on the distribution system that need to be replaced.

Idube inspectors have experience of more than 200 000 wood utility poles, inspected and treated. Included in our service is a comprehensive electronic data-base tailored to conform to the client’s requirements.
