The utility company has traditionally used wooden poles treated with Creosote wood preservative. Following the recent re-classification of Creosote by the European Commission as a Class 1b Carcinogen, many European utilities are looking at safer alternatives to Creosote treatment.
If we also factor in the possibility of Creosote bleeding, where liquid Creosote can bleed out of the pole surface under certain climatic conditions, the need for change is clear: To protect both utility employees and members of the public from coming into contact with Creosote.
There are a range of safer alternative wood preservatives based on copper as the main active fungicide. Utility concerns over the longer-term performance of these wood preservatives, as well as attack by copper-tolerant fungi, have led many utilities to look for additional protection against groundline decay. This occurs at the ground line section of the pole, where mechanical loading and the likelihood of decay over time is high.
The selection criteria set by the utility included the following requirements:
Following an extensive review by the utility, Polesaver composite ground line barrier sleeves were selected for use with a copper in oil type wood preservative treated to a high retention level.
Installation of Polesaver sleeved poles commenced in 2021. With only small changes in work practices required, the switchover has been trouble-free. Both utility and sub-contractor employees commented positively about the clean and odour-free alternatives.
