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 RESIS-
TANCE WITH LOWER POWER CAPAC-
ITY IS REQUIRED USE OUR ROUND
WIRE DESIGN.
THESE RESISTORS ARE CON-
STRUCTED OF A HEAVY RESISTANCE
ALLOY MOUNTED ON CERAMIC
INSULATORS AND SUPPORTED BY
A METAL MOUNTING BRACKET.
METAL PARTS, EXCEPT FOR THE
RESISTANCE ELEMENT, ARE HEAV-
ILY PLATED TO PREVENT OXIDATION
AT HIGH OPERATING TEMPERATURES
AND TO PREVENT CORROSION. THE
MOUNTING BAR IS SLOTTED ON
EACH END TO FACILITATE INSTALLA-
TION. EDGEWOUND UNITS PROVIDE
CLAMP-TYPE TERMINALS, PERMIT-
TING A RELIABLE CONNECTION
WHICH CAN BE MOVED ALONG
THE RESISTIVE ELEMENT TO OBTAIN
INTERMEDIATE VALUES.
