Embodiment 1

[0090] Figure 28 An example of a utility pole of the invention ready for industrial production is shown in full size.

[0091] Determination of the individual dimensions of the parts forming the utility pole of this embodiment was carried out by, using a finite element software package, considering first the mechanical stresses and strains that the utility pole must resist and secondly the strength of the reinforcing polymer from which the parts are made. Resistance and the direction of these resistances (compression-formed isotropic materials for joints and caps and pultruded anisotropic materials for cylindrical parts).

[0092] The utility pole of this embodiment is 7m long and complies with the requirements regarding specifications for correspondingly sized utility poles suitable for installation in the network. It also meets the requirements of relevant international standards (EN 50341, EN 50423).

Abstract

The invention relates to modular fiber reinforced plastic (FRP) poles, suitable for distribution of electricity, telecommunications, lighting and all the other uses relevant to the poles, consisting of successive concave parts of constant cross section (tubes) of various shapes, corresponding annular joints and cap, which are joined together adhesively or / and mechanically. Production method of thepoles of the invention, consisting of the assembly of the individual parts, which can be produced industrially in a cost effective manner by the methods of pultrusion (concave parts - tubes) and compression molding (annular joints and cap). Use of the poles of the invention, which can be provided either fully assembled or as a modular product into separate individual parts, packaged in such a wayin order to save storage and transportation space and accompanied by the necessary materials, tools and manuals for their assembly and installation on-site.

Description

technical field [0001] The invention relates to utility poles made of reinforced polymers (Fiber Reinforced Plastics - FRP), a method of production of utility poles and the use of utility poles as modular products. Background technique [0002] Reinforced polymers belong to the category of composite materials and are composed of polymers and reinforcing glass fibers or other materials (aramid, carbon, etc.) in various forms (yarns, mats, felts, fabrics, grids). [0003] Utility poles are widely used for overhead distribution lines, telecommunications transmission line support, and for a variety of public and private uses (lighting, road signs, camera mounts, flagpoles, etc.). [0004] The first applications for overhead utility lines, lighting, telecommunications, etc. were made using wooden utility poles, as they were easier and cheaper to produce by harvesting trees. They also have the advantage of being insulating. Consequently, wooden utility poles are the dominant tec...
