Specifications

Advantages: long service life, resilience, easy to handle, tough, easily workable, maintenance free, safe in use, economical

Our poles are made from pine or spruce wood. Trees for the poles production are felled  in winter season 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.

Basic parameters:

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

Pressure during impregnation 0,9 – 1,0 MPa/ 6 – 8 hour.

After impregnation drying vacuum (-) 0,02 MPa/15 minutes.

 

Applied preservatines:

 

Wolmanit CX-8 – water-solvable wood protection agent based on cooper and boron compounds, delivered by Dr. Wolman GmbH company (Germany)

Solution concentration  3,5 – 4,0 %.

Wood Saturation 4 kg/m3.

 

Tanalith E – water-solvable agent  based on cooper compounds and derivatives of aliphatic amines (triazoles) Arch Timber Protection Company (England)

Solution concentration  3,5 – 4,0 %.

Wood Saturation (retention) 4 kg/m3.
