Aluminum power resistor
It is an aluminum encased resistor
Variable wire wound power resistor
Slide type resistor - Consists of a tubular ceramic form having copper-alloy or chromium-alloy windings as a resistance element, with the resistor mount attachment method being the same as the other resistors described.
Except for the sliding contact surface on the windings, the entire component is coated with a high-temperature, non-flammable resin.
The adjustment mechanism is a rotating point that slides directly on the resistance element
A tubular ceramic resistor has two terminals, and is wound with copper wire or chromium alloy wire to provide the resistance and then coated with a high temperature, non-flammable resin
SQ cement resistors are made by winding resistance wires around non-alkaline ceramic core, which is added with a layer of heat and humidity resistant and non-corrosive protective material
