Take a deep dive into Prysmian’s high-voltage underground cables system and solution. Prysmian Group is the undisputed leader in high-voltage land cable systems and solutions that are fundamental parts of power grids across the world.

Prysmian’s Abbeville, SC, facility is home to a vertical continuous vulcanization line for the production of high-voltage (HV) and extra-high-voltage (EHV) cables. Added in 2009 as part of a $46 million investment into the facility, the line provides state-of-the-art EHV production technology, giving customers world-class products produced domestically. Since beginning production, the vertical continuous vulcanization line has supplied power cables to major utilities and industrial customers around the world to support over 300 projects. That’s approximately six million feet of high-voltage cable. That is equivalent to the distance between New York City and Tampa, FL.

Prysmian employs a North American-based organization of engineering and operations personnel dedicated to providing turnkey high-voltage underground project services from cable and accessory installation and termination services to onsite testing, asset monitoring and support. Our team has experience with the largest and most complicated projects ever installed in North America. Prysmian’s locally based project team allows us to self-perform 100% of critical project tasks ranging from preliminary engineering through final commissioning testing. The integrated nature of our group ensures that projects can be executed to the highest standards with the greatest efficiency.

In addition to being the world’s largest HV/EHV cable manufacturer, Prysmian is one of the largest cable installation contractors in North America, capable of managing multiple large-scale projects across the country. Prysmian’s dedicated team of installers specialize in HV/EHV cable installation, resulting in unparalleled experience and competence to complete the most challenging activities. The absence of third-party contractors prevents external coordination and planning issues from impacting project schedules.
