Impregnated Wire Pole

Wooden Poles

Impregnated Wire Pole

Treated pine wire pole in light, medium and heavy classes for overhead wires.

Species
Pine

A wire pole keeps the wires of an overhead line hanging with a balanced sag. As the wires get longer, thicker and more numerous, the load on the pole grows. On windswept uplands and in winters with heavy snow, that load grows even more.

Our wire poles are made 9 to 12 metres long in three classes. The body is pine, impregnated under vacuum and pressure; the part below ground is protected too. The light class is used on short spans, the medium class on standard lines and the heavy class at angle and end points. If you write the climate of your region and the spans, we will suggest the right class.

Wire pole sizes are not just length and class; the setting depth and the height left above ground are counted too. On soft ground choosing a pole one length longer gives the depth needed while keeping the wire's height above ground.

Advantages

  • Easy to haul: far lighter than a concrete pole of the same length.
  • Gives under impact: takes a vehicle strike or a storm without snapping.
  • Does not conduct: the wooden body gives maintenance crews extra safety.
  • Worked on site: no special tools are needed for holes and cuts.

Areas of use

Overhead lines, upland and village lines, regions with high wind and snow loads.

Frequently asked questions

What do the letters H, O and A on poles mean?

The letters are the pole's thickness class: H light, O medium, A heavy. For poles of the same length, the higher the class, the larger the top and butt diameters and the more load the pole carries. The diameter limits of each class are defined in TS EN 14229 and appear in the table on the product pages.
