Because of their light weight, composite towers are easier to transport. The same flatbed truck that carries three concrete towers can haul 72 composite poles. McCombs says they can be lifted to remote sites by helicopter. Their light weight also makes them easier to manipulate and install. The poles are completely field-modifiable.
Fittings slip into vertical notches running the length of the pole.
They then lock into place by tightening a molly-type bolt that squeezes them against the sides of the notch. The system can be used with conventional transmission line hardware of Composite Power's own configurations. Once installed, composite poles resist corrosion and insect and fungal attack. Accelerated aging tests suggest lifespans of more than 50 years. Because they are insulating, they do not attract lightning, the most common cause of line outages.
