U-503's Along the Street
By David Dahle
|At the left, four yellow U-503's on a pole.|
|At the right, a pole with three yellow U-503's and two brown U-502 Westinghouse. Note the broken conductor on the left, and the poor splicing job on the wire!|
The yellow U-503's in these pictures are on old street lighting lines operated by the City of Sioux Falls, SD. They had also used a few yellow U-503's on their old 2400V lines, but all those lines have since been upgraded or dismantled.
The yellow U-503s are just one of the many types of insulators used over the years by the City of Sioux Falls, SD.
You can read my story about The Yellow U-503 Cache for more information.
