Pultruded profiles or tubes and rods have been successfully in service in electrical applications for 20 years. They are used in electrical motors, generators, transformers, power stations, etc. In power stations and transformer buildings, they are used for walkways, platforms and cable trays. The electrical insulation is most often combined with the need for high strength and low weight, not to mention corrosion resistance and fire retardancy.

Fiberbar rebar for concrete reinforcement is also used in electrical environments, when used in the foundations, walls and roofs of buildings for transformers and reactors. Fiberbar rebar provides electromagnetic transparancy.

Fibreglass profiles are also used as structures for telecommunications towers. The electronic signals pass through the fibreglass structures without distortion.
