JEA will be modifying six 230kV transmission circuits to increase clearances over the St. Johns River in Jacksonville, FL to provide access for Post-Panamax class shipping vessels.to JaxPort. The project is comprised of six (6) PyraMax towers, and twelve (12) monopole structures to be installed among the six circuits. Additionally, the project requires modification of the distribution within the project sites that feed the FAA lighting systems. Both overhead and underground distribution primary and secondary will be required. New FAA lighting systems will be installed on new structures. · New transmission conductor will be 1033.5 ACCS/TW-C7 Ocala Type 16 by others. · Existing conductors include 1590 ACSR Falcon and 954 ACSR Cardinal by others. · New OPGW will be 72-count SMF by others. · Existing OHGW include 3#6 AW by others. · New insulators will be toughened glass. · New distribution overhead conductor will be 1/0 AAAC Primary & Neutral · New distribution underground cable will be 1/0, 28kV Single Conductor AL
