Northwire Inc., a custom-designed cabling company, is opening new markets for robotic cables that flex by using DuPont™ Hytrel® thermoplastic polyester elastomer for insulation. “Because of its combination of high mechanical strength and dielectric strength, we can use Hytrel® in thinner layers than many alternative materials,” said Ted Beach, director of sales, Northwire.
In multi-conductor cables, thinner insulation results in a substantial reduction in cable diameter, which means longer flex life at a given bend radius. Slimmer cables can permit tighter bends while meeting a particular flex life target.
Northwire also is delivering the benefits of Hytrel® in cables that flex in other fields ranging from lift bridges to retractable cables for telescoping antennas on mobile broadcasting vehicles.
In Northwire’s UL-recognized robotic cable, a tough, thin layer of DuPont™ Hytrel® provides effective insulation and excellent flex life.
