Research into the possibility of the production of glue-laminated electro-conducting poles

The paper presents the results of research into the production possibility of laminated poles from the wood elements of fir, alder and poplar glued by resorcin-phenol-formaldehyde. Before gluing the elements were treated by preservatives. Preserving process and gluing were carried out in accordance with the set testing plans. The tests were performed in laboratory and field conditions. Experimental poles were put up in outdoor climatic conditions in order to test their behaviour for some time.
