Advantages and disadvantages of a wire wound resistor
Electricity has become an indispensable part of our daily life, and the use of electricity is more and more extensive, but the existence of electricity also has a certain degree of danger. The higher the current, the greater the danger, so the use of wire-wound resistors The role is highlighted. What is a wire wound resistor : Wire-wound resistors are constructed by winding resistance wires on an insulating frame. The resistance wires are generally made of nickel-chromium and manganese-copper alloys with a little resistivity. The insulating frame is made of ceramic, plastic, metal coated with an insulating layer and other materials into a tube shape, a flat shape and other shapes. The resistance wire can be wound into one layer or multiple layers on the frame as required, or a non-inductive winding method can be used. This kind of resistance is divided into fixed and variable. It is characterized by strong working stability, good heat resistance, small error range, and the ...
