Cement Resistor

Cement resistors are resistors filled with cement (actually not cement but refractory mud), that is, the resistance wire is wound on non-alkali heat-resistant ceramics, and heat-resistant, moisture-resistant and corrosion-resistant materials are added on the outside to protect and fix it The wire-wound resistor is placed in a square porcelain frame and filled with a special non-combustible heat-resistant cement.

There are two types of cement resistor series: ordinary cement resistors and cement wire wound resistors. Cement resistor is a kind of wire-wound resistor, It belongs to a resistor with higher power and can allow a larger current to pass.

Cement resistors series are widely used in power adapters, audio equipment, audio frequency dividers, instruments, meters, televisions, automobiles and other equipment.
