Entergy Services, Inc.

Mississippi River Crossing, 230kV Transmission Line, LA

This extraordinary project consisted of the installation of a 230kV transmission line underneath the Mississippi River. To accomplish the work, Entergy negotiated the bore under a separate contract and issued a single RFP to the cable manufacturers for supply and installation of two circuits of 230kV XLPE cable. The RFP also required the supply and installation of a spare cable for each circuit as well.

Wilson was awarded the contract by J-Power Corp./Sumitomo Electric for the installation and termination of eight 230kV cables. The cables were 2500mm2 segmental CU conductor and utilized individually insulated strands to eliminate the skin effect. The total length of the run was approximately 3,300 feet.
