To safeguard against this, in 2017, Lehighton Light and Power began using Polesaver barrier sleeves which are designed to prevent wooden poles from ground-line rot. When applied to the wooden pole, the Polesaver dual layer barrier sleeve forms an airtight and watertight seal - elements that are necessary for decay to occur. With the ground-line section of the pole isolated from the causes of decay, the wooden pole will maintain 100% of its strength over the duration of its service life.
Lonny Armbruster, Lehighton Light and Power’s Superintendent, said he was excited to have been made aware of a solution to prevent ground-line decay from a company based in the United Kingdom. He said that Polesaver has been manufacturing products that have been safeguarding in-ground posts and poles from decay, since 1994.
“The technology has a proven in-service track record with more than 8 million barrier sleeves sold worldwide over 25 years and this, coupled with extensive independent test data from prominent European and USA testing establishments, made the decision to invest in Polesaver very easy” said Mr Armbruster. “Polesaver is a tried and test product with an excellent reputation.
The sleeves are sent to us directly from the United Kingdom and our people apply them quickly and easily to the new poles in our pole yard. The Polesaver protected poles are then transported to site and erected.”
Richard George, Polesaver’s CEO, said he was pleased that Lehighton Light and Power were now an established customer of Polesaver UK and he looked forward to supplying the barrier sleeves for many years to come.
50 installation engineers attended a 2 day training session organized my Umeme at its headquarters in Kampala, Uganda. The purpose of the training was to demonstrate the benefits of applying a Polesaver sleeve to wooden utility poles.
Peter Williams, Director of Global Business Development for Polesaver UK, commenced the two day event with a formal presentation which educated the delegates about the threats of ground-line decay on wooden poles, and how this threat can be prevented. Simply by applying a Polesaver sleeve to the pole at the correct place, ground-rot and core-rot can be eliminated, resulting in the pole having a significantly extended service life.
The classroom session ended with an informative questions and answers session.
The following day, all of the installation engineers took part in a practical exercise of applying the sleeves to poles in Umeme’s pole yard.
They were taught the safety principles of working with LPG gas bottles and the safe use of gas torches. This was followed by a practical demonstration on how to correctly apply Polesaver sleeves to poles. During the course of the day, each delegate was given the opportunity of applying several sleeves to poles.
Polesaver’s Director Peter Williams assessed their level of competence. At the end of the day, everyone, without exception had achieved the standard necessary to apply Polesaver sleeves correctly.
Certificates of competence were presented to each participant.
Umeme’s project manager, Mr Dan Tumuhimbise, announced to the team that he was delighted with the level of success they had achieved after only one day’s training.
He said, that by using Polesaver sleeves, it aligned extremely well with Umeme’s core values of Safety, Customer Service and Innovation.
Furthermore, he said that Umeme were always looking for better ways to do things, and, by adopting Polesaver sleeves, this clearly shows that Umeme are embracing new technology. Poles, with Polesaver applied, will be safer and the electrical networks they support will be more reliable, thus leading to greater customer service.
Mr. PJ McGarrigle, Umeme’s Network Asset Manager, addressed the engineers at the end of the day. He explained that, currently, some poles in Uganda are lasting only a very short time (typically, between 2 and 5 years). He said that this was unsustainable and, therefore, something had to be done.
By adopting Polesaver as standard on all future pole installations, it will ensure that Umeme’s wooden pole network will last for many, many years and thus prove to be excellent value for money, as well as offering a safer and more reliable network.
Mr. Kevin Bwire, Network Asset Information Manager, said that the RFID technology incorporated into the Polesaver sleeves, would enable Umeme to map out and manage its pole network successfully.
The RFID technology enables companies to identify the exact GPS location of each pole in its network. Also, additional information can be assigned to the company’s database, for example, date of installation, who supplied the pole, type of preservative used and schedule of future inspections.
Photographs of the pole can also be uploaded to the company’s asset tracking database, to enable engineers to track the condition of each pole in its network.
Mr Dan Tumuhimbise said that Umeme intended to start the national roll out of Polesaver with effect from 26th June 2017. From this date onward, all poles erected by Umeme will have a Polesaver sleeve applied.
Peter Williams of Polesaver, added that he was impressed with the overall enthusiasm, dedication and pride the Umeme installation team had demonstrated during the two day training programme.
As I boarded the O.A bus from Bolgatanga to Accra, I gave a sigh of relief from the mighty harmattan which had wrestled me throughout my entire stay during the Christmas holidays. Little did I know that the grass along both sides of the road had had their own share of pain from the devastating twin brother (fire) of the harmattan. As flood washes away structures elsewhere in the capital, fire swoops the entire grassland in the Savanna belt of Ghana.What a pity!!!
Throughout the journey, the electrical engineer in me could not help but take into account the effects of these fires to the electrical poles erected in the grassland or similar conditions. Putting cost to the replacement of these poles and the loss of electricity supply made me cringe inside. For a moment, I was excited that this problem was outside the boundaries of ECG and my company was insured. Then I had an electrical epiphany, I remembered that this phenomenon of pole burning is not limited to NEDCo (Distribution Company for Northern Ghana) because several of ECG’s districts have poles planted in bushfire prone areas.
After taking my shower when I arrived in Accra, I started to think through as to what solution could be suitable in addressing this pole burning phenomenon with the least cost. As an R&D Engineer, the only convincing answer that came to mind was the use of steel poles which ECG is already employing. However, the cost of replacing all wooden poles in bush fire prone areas is unconceivable. Mind you the cost of steel poles is almost twice as much as the wooden poles. “How economical is changing all wooden poles that are likely to burn due to intermittent bush fires with steel ones? There must be a way out,” I thought to myself.
Upon resumption of work, I had discussions with my boss nicknamed Dr. Ferroresonnance (I pray he does not read this article), he made me aware of a proposed solution to the pole burning phenomenon with the use of a fire protection fabric. “Fabric!!!” I exclaimed unbelievably and in a state of shock. “What type of fabric can save a pole from bush fire?” I queried. I was giving a brochure and manual about the product to help my ignorance and engage my curiosity.
A pilot project was proposed for 5 ECG regions with a total of 2000 poles considered. The fire protection fabric was wrapped around the base of the pole up to about 6feet.
My visit to the pilot project site revealed that 50% of the project sites had experienced bush fires after the fire protection fabric was installed. To my surprise, not a single pole with the fire protection fabric got burnt. The evidence became clear when it was observed that other poles without the fabric within the same vicinity were burnt. (There are pictures attached to this article that verifies my claim). Still not convinced, I decided to gather a number of the dry grass/weeds under one pole protected by the fabric and then set it on fire. This happened at a cleared piece of land in a village next to Otuam, the hometown of the former president of Ghana, the late J.E.A. Mills.
The farmers and my entire team at the site watched the demonstration in awe as the fire had no effect on the pole under investigation. After five minutes under that intense flame, we quenched the fire after a successful demonstration. The fabric itself had not damaged only the sooth from the fire, that had settled on the surface but it was washed away by water. I remembered that famous quote from the Good Book “for lack of knowledge my people perish”.
As a child finding solutions to problems has been my passion and this drove me to pursue an engineering career. I felt fulfilled when feedback from all the districts which the pilot exercise was carried out was extremely positive. The project is expected to be rolled over to all poles under ECG jurisdiction. Finally, an economical solution has been found for the burning poles, Oh pole protection fabric, thou art a Pole Saver. My job as a researcher still continues……….

Polesaver launches new Creosote Bleed Protection kit. It is well known that Creosoted wooden utility poles can bleed creosote to the surface in warm weather. This kit covers the pole surface with an impermeable barrier to contain creosote bleed, whilst any creosote running down the pole is directed behind the impermeable barrier by a unique spacer system.
Find more information here: Polesaver Creosote Bleed Protection Kit
To help reduce the environmental impact a number of Northern European and African utilities are now using Polesaver sleeves to reduce Creosote loss to the ground as well as giving extra protection to the ground line section of the pole especially to prevent early pole failures due to core rot. Wood preservative generally provides no protection from core rot..
