CHEC energizes new transmission cables over Oregon Inlet

On February 27 & 28, CHEC and contract crews completed the installation, testing and energizing of the transmission

cables that are attached to the new bridge over Oregon Inlet. The new 115kv transmission lines span the

2.8 miles of the bridge in fiberglass conduit, which are held in place by a hanger system located underneath the girder

sections and inside the segmented box sections of the new bridge. The project includes four splice boxes, necessitating

20 cable runs and 24 splices and terminations throughout the project. The new transmission cable system is rated for

100 MW load and includes a spare cable, improving reliability for Hatteras and Ocracoke islands.

Contract crews from New River Electrical, South Wire High Voltage Solutions and Lee Electrical Construction worked

along side CHEC to complete the project. Booth and Associates provided engineering consultation throughout the project.

CHEC’s staff and directors have anticipated the historic opening of the new bridge and have long awaited the day

when the cooperative would energize new transmission cables over the inlet. This project further ensures safe and reliable

delivery of electric service to Hatteras and Ocracoke Islands for years to come.
