Description:
Wirewound Power Resistors feature corrosion resistant wire, helically wound into a long spring-like coil. The coil is then wound onto a spirally grooved, solid porcelain core, where each end of the wire is fitted to a terminal, which clamps to the end of the core. Terminals, clamps, and all related hardware are made from heavy stainless steel. The resistors are typically mounted between "L" brackets, using a 'throughbolt'. Multiple mounting racks are often furnished. This construction can be supplied open or with enclosures for personnel protection, or louvered enclosures for both personnel and all weather protection.
Features:
FDL Series terminals are formed at a 90 angle to allow the use of flat bus-connectors. This eliminates the need for cumbersome jumper wires when interconnecting resistors. The open 'double helix' design permits considerably more wire to be wound around the porcelain core. The electrically efficient construction of the GWR element allows the highest possible wattage ratings per linear inch, consistent with NEMA standards performance. As an added benefit, the same design feature that permits the high wattage ratings, (so much more of the wire surface is exposed to the air), makes the GWR Series Resistors an excellent space heater, both for natural convection and forced air use. Post Glover's GWR resistors are available UL Recognized and CSA Certified.
Applications:
•Small horsepower crane control
