Tubular Power Wirewound Resistors are available in:
Commonly used in dc and ac low frequency circuits where appreciable power need be dissipated. Designed to meet the most demanding mechanical and electrical requirements. Rated at 350°c when suspended horizontally in free air. Cured at low temperatures therefore able to use heavier wire - increasing the transfer of heat from the interior of the resistor to the terminal, reducing hot spot temperature, dissipating overloads quicker and keeping the resistor cooler with increased reliability resulting in greater stability and longer life.
