Optical-fiber network saddles for use in routing fiber-optic cable are designed with rounded edges to provide a smooth surface between the mount and the cable. This helps prevent potential stress on the cable and damage to insulation resulting from snagging or abrasion. Saddles are available in single-capacity versions for a maximum bundle size of 1.
Radiant floor-heating pump improves control and energy use in primary- and secondary-piping configurations.
AC adjustable-frequency drives save up to 40 percent of fan-motor energy compared to standard fixed-airflow systems. In cooling-tower applications, drives reduce fan noise and eliminate fan cycling as well as the need for output-water throttling valves, while maintaining water at design temperatures.
Transformer protector is designed exclusively for primary-side applications on distribution substation transformers rated up to 60 MVA at138 kV. Electrically linked, manually reset pole-units provide less than 1/4-cycle, three-phase tripping simultaneity. The device is compatible with any relay-tripping system.
