Characteristics - Electrical
Derating Curve
These high power tubular resistors have a high resistance to heat, and a small
resistance to temperature co-efficient. Relatively small in size, their ability to take a
large load make them ideal for use in heavy electrical machinery. Available as
standard wire-wound resistor coated with flameproof enamel paint or ribbon style also
coated with flameproof enamel paint.
