- Lake Circuit No. 6 and 7 Line Upgrade Project
- The proposed project consists of the reconstruction of an approximate one-mile section of and existing overhead 69,000 volt (69 kV) sub-transmission power line (Lake Circuit No. 7) and installation of a second circuit (Lake Circuit No. 6). The existing line consists of three electrical conductors (wires) supported on wood poles. Existing conductors will be replaced with a slightly larger diameter (a 0.098" increase) conductor and a second circuit (Lake Circuit No. 6) consisting of three additional conductors will be installed--for a total of 6 conductors. This upgrade line will extend from SMUD's existing Lake Substation south within an existing utility corridor to the south side of Iron Point Road where it will connect to existing underground circuits. The addition of a second circuit requires eleven existing wood poles to be replaced with slightly taller (up to 11 ft) and stronger poles. Seven concrete poles (natural gray color, armless construction), three wood poles H-Frame (two wood poles connected by steel crossarm, used for line crossings), and one steel pole (self-supporting, unguyed, angle pole) will be used.
