American Electric of Jacksonville has been hired for military contracting with Navel Station Mayport to install primary wire. The navy base is located northwest of Jacksonville where the St. Johns River meets the Atlantic Ocean. We installed 800 ft of primary wire from transformer to transformer through a manhole as a backfed grid system to restore power if it goes out.
We layed a 6″ PVC conduit in ditch to protect the primary wire then encased the conduit in concrete, with a copper locate wire inside, shown in the photo. A bare copper wire was also placed on top of the concrete to counterpoise, providing a grounding path for a lightening strike. The concrete was then left to dry for a day and was back-filled.
The manhole had to be core-bored and grouted where the conduit entered. And, the copper wire entering then had to be fire-taped and racked around the hole, completing the project.
American Electric of Jacksonville is grateful for the men and women who serve in our military and are proud to provide our reliable services. To our luck during this project, the USS Iwo Jima was even present, shown in the background of the photo.
