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.
