Answer: The term "power line" is a general term that refers to any line carrying electricity, from the high-voltage lines that span vast distances to the smaller lines that bring power directly to your home. A "transmission line" is a specific type of power line. It is a high-voltage line (typically 69 kV and above) used to transport large amounts of electricity over long distances from a power plant to a substation. All transmission lines are power lines, but not all power lines are transmission lines. We specialize in providing the necessary equipment for both.
