Polyethylene molding for cable terminiations
Since 1975, Teledyne D.G.O’Brien has put over 25,000 molded polyethylene cable terminations in penetrators, array systems and other applications, from shipboard to the seabed.
Polyethylene is favored for its very low moisture absorption. It's the appropriate jacket insulation whenever long-term moisture exposure threatens to degrade electrical or optical performance over time.
Polyethylene cable joints can be brittle if not manufactured properly, so Teledyne D.G.O’Brien oversees the process with cable manufacturers and operates a tightly controlled, computer-driven molding system of our own design and manufacture.
The process is precisely developed and controlled, but the outcome results in 25-year longevities. Bond delamination is not an issue. Polyethylene-molded hull penetrators we built for Trident submarines in the 1970s are still in service.
Should cable systems require fabrication at your site, Teledyne D.G.O’Brien field technicians take portable molding machines to your facility with the same quality assurance we provide from our factory.
