A tubular ceramic resistor has a fixed number of windings and is wound with alloy wire as a resistance element.  The staggering wound is made according to the desired resistance value, followed by the placement of the component mounts. It provides high starter resistor power and is durable, is high temperature-resistant, dissipates heat well, has a low temperature coefficient that varies in direct proportion, and is suitable for application loads involving brief current surges. Due to the set number of windings on the ceramic form, the resistance value range is relatively low. Tolerance is ±10% and this product is available in various shapes or in resistance boxes. Suitable for motor starters, load measurements, industrial machinery, electric power distribution, instrumentation, and automation control installations, etc.
