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.

High Power Tubular Resistors
Type TT Series
Type TTR Series
These resistors are made by winding resistance ribbon around a ceramic tube in a wave shape, externally
coated with enamel.
They are extremely good in dissipation of heat, and their small size vs large current capacity makes them ideal
where space is at a premium.
