TRANSMISSION lines are much larger than distribution lines. Their support structures come in a variety of shapes and heights. They can be made of metal latticework, concrete or wood, but the wooden structures are taller than distribution line poles.
Transmission lines are generally located in cleared corridors called rights-of-way.
Transmission lines carry from 44,000 to over 735,000 volts.
DANGER! These high-voltage lines are not insulated, and nothing should come near them. Carrying out work near these lines or planting anything in the right-of-way without proper authorization is prohibited.
