Power resistors
Wire-wound resistor tubes
High-class ceramic tubes and perfect windings are the basis of
the high quality of our resistors and they make a long service
life as well as a great reliability possible. By means of a layer
made of a special cementation the windings are mechanically
fixed and protected against mechanical impacts from outside.
Moreover, the heat conduction is improved. In order to adapt
the resistance value, regulating clamps can be put onto the windings.
Wire-wound resistor tubes in basic version without regulating
clamp and without clamping bolt
winding support: ceramic
winding: CuNi 44
For the resistor’s winding we use round resistor wire or resistor
band with a low thermal coefficient of resistance. Our resistors
are outstandingly suitable for applications requiring a high resistance
accuracy over a broad temperature range. Thanks to
the high resistance accuracy, there are no tolerances concerning
the resistance values.
capacitance: DIN = 0,5– 0,8 W/cm 2
MAX. = 0,7–1,0 W/cm 2
rated voltage
for air gaps and
creep distances: 600 V AC or DC
