  • HIGH-CAPACITY/EFFICIENCY TRANSMISSION LINE DESIGN
    Publication number: 20150083483
    Abstract: A transmission tower structure for suspending from an arched crossarm a three phased circuit arranged in a compact delta configuration that improves the surge impedance loading (SIL) of a transmission line, reduces its series impedance, lowers both resistive and corona losses, and moderates electromagnetic fields and audible noise effects at the ground level—all achieved in a cost effective manner. The structure further has a low overall height and aesthetic appearance enhancing the public acceptance of the embodiments.
