Product introduction
Cement resistor is a resistor sealed with refractory mud, that is, the resistance wire is wound on non alkaline heat-resistant porcelain, and heat-resistant
Wrap and fix with moisture-resistant and corrosion-resistant materials, and put the wire wound resistor into the square porcelain frame, and seal it with special incombustible heat-resistant cement.
Cement resistor is a kind of wire wound resistor. It belongs to the resistance with large power and can allow a large current to pass through. Its role is the same as that of general resistors,
It can only be used in occasions with large current, such as in series with the motor to limit the starting current of the motor, and the resistance value is generally not large. The cement resistor has a large overall size
Shock resistance, moisture resistance and heat resistance, good heat dissipation and low price. It is widely used in power adapter, audio equipment, audio frequency divider, instruments, meters, TV sets, automobiles and other equipment.
Advantages of cement resistors
■ shock resistance, moisture resistance, heat resistance and good heat dissipation;
■ insulation, suitable for printed circuit board;
■ winding the wire on the porcelain rod and then welding the joint to make accurate resistance value and prolong the service life;
■ the high resistance is made of metal oxide film instead of winding;
■ good heat resistance, small temperature coefficient of resistance and linear change;
■ short time overload resistance, low noise;
■ good explosion-proof performance and protection;
Product application
Cement resistors are usually used in occasions with high power and current. There are 5W, 7W, 10W, 15W, 20W or even higher power, such as air
conditioners, televisions and other electrical appliances with power of more than 100 watts. Basically, cement resistors are used.
