European Spruce (Picea Abies), Scots Pine (Pinus Sylvestris)
Benefits: long service life, resilience, easy to handle, tough, easily workable, maintenance free, safe in use, economical
Wooden telephone and power poles sized from 6 to 9 meter long (poles diameters given in the table below) are our basic products. Poles are made from pine or spruce wood. Trees for the poles production are felled in winter season at the area of Lower Silesia. Timber is of standard value.
Poles can be set directly in ground.
Against the negative environmental influence poles are protected with impregnating agents by pressure method.
Preffered poles dimensions:
Pole length [m] (deviation +/- 1%)
Top Diameter 60cm from the top [mm]
Diameter 150cm from butt end [mm]
Spiece of wood:
- Scots pine (pinus sylvestris)
- European spruce (picea abies)
Wood class WCO1, grown in Northern Europe
Sweep and crook permitted to the extent that a straight line from the centre of the top to the centre of the pole 1,5 m from butt remains within the pole.
Knots up to 4 cm.
Other parameters in accordance with British Standard BS 1990-1:1984
We also follow Buyers’ individual requirements on the technical parameters.
Technology of impregnation:
Wooden poles impregnation consists in a full penetration with preservative of the sapwood up to heartwood which is naturally impregnated.
IV class wood impregnation is applied for telecommunication poles being in a permanent contact with the ground and/or water to protect them against insects, fungi, leaching and decay for a few decades of years.
Impregnation process is carried out in autoclave using Behtell or Rüping pressure – vacuum method.
Wooden poles moisture prior to treatment < 25 %.
Underpressure before impregnation (-) 0,02 MPa/ 0,5 hour
