Where did the idea come from?
Development of the Jerol distribution pole started in 2008, after a fatal accident at a Swedish utility company, where a timber pole became conductive. Soon after, the first distribution poles were installed in the north of Sweden in the winter of 2009. So far over 3500 distribution poles have been installed in Sweden, Norway and Finland in 75 different projects. The response from customers has been 100% positive.
What is a Jerol Composite Utility Pole ?
The Jerol composite pole consists of two layers; an inner fibre composite (GRP) and an outer layer of tough 3-4 mm coloured UV stable polyethylene (PE).
The core gives the pole its strength, which can be varied by increasing the thickness. The polyethylene offers high levels of UV protection and a tough outer layer enabling the pole to be safely climbed . This material combination makes this pole light and easy to install, yet strong enough to cope with the most demanding of loads. Also because the pole is hollow you have the option of routing cables internally.
The installation method of our composite pole is the same as a timber pole, which means existing crews can install the poles with minimal training and standard equipment. Swedish climbers can be used to ascend the pole safely.
The pole is manufactured in standard lengths up to 16 m. Taller poles up to 24 m can be produced to order.
The pole is significantly lighter than a timber pole, the weight of a 10 metre Medium pole is 213 kg, and a 12metre Stout pole weighs in at just 402 kg, about half the weight of the equivalent timber pole.
The diameter of the pole is very consistent, varying by only a few millimetres throughout its length, unlike timber poles that taper considerably.
The wall thickness of 12-40 mm varies depending on the length and load requirements of the pole. The pole is strong enough to handle all current equipment.
No leaching of carcinogenic pollutants that can harm the environment.
Storing and waste handling
Our composite poles are non-toxic, so no special storage precautions are needed. The poles can be reused or cut into pieces and used as ground sockets or cable protection. Damaged pole pieces can be submitted to a recycling facility to be used as fuel.

Better for the Environment
The environment should be one of the key considerations when choosing new or replacing existing distribution poles. This is where our composite pole comes in, as it is the perfect environmental solution. Our poles are non-toxic and a giant technological leap forward from when creosote impregnated timber poles were the only option.
Today, millions of creosote poles carry cable networks across farm land, forests, meadows and cities of every country. Creosote is extremely toxic and has powerful carcinogenic properties, which leach into land and water courses, causing environmental damage, not to mention the risk to the installation personnel. Our composite distribution pole, on the other hand, contains no such toxic elements.
- A network with leak-proof poles for power and telecom networks sends a sincere message that you are environmentally focused and want to protect and conserve our natural landscapes.
- As our distribution poles are non toxic, an environmental authority permit is not required for temporary or permanent storage.
- The pole can be coated in a range of RAL colours to suit the surrounding or setting.
- Our distribution pole does not contain any carcinogenic material meaning that it is far safer for the installation crew.

Quality & Traceability
The Jerol composite pole is a completely man-made product, allowing full control of the manufacturing process and 100% consistency from one pole to the next. This is achieved by utilising the latest computerised production and quality management technology. Each and every pole that leaves the facility matches the specified dimensions perfectly.
The pull tests that have been carried out on both Medium and Stout poles, prove that the overall pole strength exceeds the safe working load for single or double stays when using the Jerol Stay Wire Fixing Kit.
Results verified by extensive testing showed that the torsional strength of the Jerol composite pole, far exceeds that of the equivalent UK timber pole. This will provide enhanced safety in the event of ice build up, falling trees or conductors breaking due to high winds.
he poles are classified as non-conductive by STRI Sweden. In the full scale test the pole was subjected to 425 kV in dry conditions without leaking current. Another test was to apply 90 kV at 600 mm distance between the electrode and ground, without leaking currents exceeding more than the EU norm limit of 0,15 mA. The poles were also tested in wet (rainy) conditions and all values were within the EU norm limits.
