Building Automation Triad Solid Cables: Where They Fit and How They Help
Windy City Wire’s Building Automation Triad Solid Cables are designed for control and signal circuits that benefit from three clearly identified conductors bundled together and twisted for consistency. The solid conductor construction provides reliable terminations on screw-clamp and spring terminals common in control panels and field devices, while the triad format reduces wiring complexity by combining power, common, and signal in a single pull. A non-shielded, TFN, 600-volt design makes these cables a practical choice for dry-location building automation work in low-noise environments and in raceway-based installations.
