Powr-Rib® Edgewound
Edgewound and Round Wire
Designed in both Edgewound and Round
Wire formats, these rugged resistors can
handle 700 to 1000 Watts of power.
Specify our Edgewound design for
very low resistance and high power
capacity. When higher resistance with lower power
capacity is required use our Round Wire design.
These resistors are constructed of a heavy resistance alloy mounted on
ceramic insulators and supported by a metal mounting bracket. Metal parts,
except for the resistance element, are heavily plated to prevent oxidation at high
operating temperatures and to prevent corrosion. The mounting bar is slotted
on each end to facilitate installation. Edgewound units provide clamp-type ter-
minals, permitting a reliable connection which can be moved along the resistive
element to obtain intermediate values.
