MODULAR COMPOSITE UTILITY POLES ARE THE FUTURE
High performance modular composite utility poles accommodate a cost effective and reliable solution where environmental conditions, high strength, weight, safety, lead time and long service life are required. Major manufacturing techniques used for production of fiberglass reinforced poles (FRP) are: filament winding, pultrusion and centrifugal casting, where the filament winding process offers advantages both in economical production and the finished end product.
ADVANTAGES OF COMPOSITE UTILITY POLES
Utility poles like power transmission & distribution and communication poles which are made of composite feature many advantages compared to poles made of conventional materials like wood, concrete and steel. Although composite poles have a higher initial investment, the use of these poles is rapidly expanding in applications where weight savings, durability and other performance benefits have critical importance. Calculated over the lifetime, composite is the best investment where the main advantages are:
Easy and fast installation minimizing placement cost, the need for highly specialized assembly crews and eliminating any additional equipment requirements
Low logistics costs with more efficient transportation and the opportunity to compose tapered poles from modular segments on the spot.
Longest life with at least 75 year service life and minimum maintenance, integrated UV protection and immunity to corrosion, rot, termites and woodpeckers.
Lowest liability, high insulating properties accommodate increased safety for workers and the public, superior mechanical properties resulting in better storm and high wind performance.
Minimal environmental impact, no potentially toxic preservatives required.
AUTOMATED LINES AND FILAMENT WINDING EQUIPMENT FOR UTILITY POLE PRODUCTION
Autonational provides both turnkey fully automated pole (segment) production lines and individual filament winding machines for pole production. Our easily sizeable & expandable lines are composed from Autonational standard modular equipment, and include integrated resin mixing & dosing, winding, curing, extraction, machining, testing and automated transport & handling, if required.
An automated pole production line consist of different machines performing different steps in the process. In the first step of production a filament winding machine winds glass fibers onto a mandrel in a prescribed pattern to form the basis of the pole structure. The winding machine receives its empty (prepared) mandrels from a automated mandrel feeder and the fiberglass yarn (also roving or fabric) is derived from a l creel system. Via the creel, the fiber is impregnated in a resin tray filled with resin before it reaches the mandrel.
In the second step a surface of resin impregnated fiber is applied. Heat is then applied, in a continuous or box oven, to initiate cross linking (hardening) of the resin. After hardening, the pole segment is removed from the mandrel, is trimmed to length and any required holes are drilled. In the final step of the process the segments can be finished with top coatings based on for example pigmented polyurethane.
ADVANTAGES OF FILAMENT WINDING PROCESS
- Suitable for high volume automated production with low labor costs.
- Poles with higher mechanical properties compared to using centrifugal casting or pultrusion.
- Allows for a wide selection of thermoset matrices such as epoxy, polyester, vinylester and polyurethane.
- Allows for the production of cylindrical, oval, & tapered utility poles.
MODULAIR POLE SYSTEM
With the filament winding machines and production lines of Autonational modular pole segments can be created which can be combined with up to eight standard-sized tubular modules to create poles with heights ranging from approx. 30 ft. (9.1 m) to 155 ft. (47.2 m) that use standard industry hardware.
COMPUTER CONTROLLED PRODUCTION AND SUPPORT
The winding process and added belonging steps are fully CNC controlled. Programmable settings define an exact orientations of the fibres over the mandrel to achieve required pole strength, thickness and flexibility. Autonational provides their customers full process support. Not only in commissioning the systems onsite, but also in providing advice on programs, pole design and process recipes. As a turnkey solution provider Autonational makes sure that your process line or tool is fully tailored to your production needs.
