EXHIBIT_D_FKEC_Q_Feeder_-_Conductor_Tensions.pdf

This is a conductor tensions reference exhibit for the Q Feeder construction project in Florida, prepared by FKEC (Florida Keys Electric Cooperative). The document provides a technical specifications table detailing the maximum conductor tensions in pounds for various wire types and conductor sizes across different temperature ranges from 30 to 100 degrees Fahrenheit. The table covers multiple feeder segments including R00 to R01, R01 to R02, Q12_BACK to Q12, Q12 to Q20, Q22 to Q24, Q24 to STR 1295, STR 1298 to Q29, Q29 to Q45, Q45 to Q55, STR 1237 to B15, and B15 Three Phase Bank segments. Conductor types specified include 336 AAC, 7#8 wire, 1/0 AAAC, and #4 HD copper, with tension values decreasing as ambient temperatures increase, reflecting standard electrical engineering principles for overhead line installations.

This exhibit serves as critical design and installation guidance for the reconstruction of 1.5 miles of 25kV three-phase overhead distribution feeder and 3.5 miles of underground feeder designated as the Q Feeder extending from Crawl Key to Marathon substation. The tension specifications ensure proper sagging and stress management during construction and maintenance operations, preventing conductor damage and ensuring system reliability. The data provided is essential for bid preparation, allowing contractors to accurately estimate installation requirements, equipment needs, and labor costs associated with the feeder rebuild and reconductoring work.
