High Power Wire Wound Resistor

The conductive wire is then wound around a non conductive core.

High power wire wound resistor.

The challenge can be how to accomplish this in optimally within the smallest possible amount of space. As a expert manufacturer of rohs approved high power slim type aluminium housed resistors we cater to a wide cross section of industries. As the name indicates the wire wound resistor consists of a resistive wire that is wound around a former of nonconductive material. The wire wound resistor is used in a variety of applications and in particular as a power resistor where larger amounts of power need to be dissipated.

Wirewound resistors are constructed using a conductive wire. We are one of the leading manufacturers of rohs certified aluminium housed chassis mounted wire wound resistors from india. Wire wound resistor construction varies widely. Following high temperature anodizing the enclosure is filled with a special non flammable silica sand it is firmly combined with resistor matrix resistance element and aluminum enclosure to keep higher.

Aluminum housed wirewound braking resistors 07 10 2013. These high power resistors can be wire wound but the most important feature of the high power resistor is of course its ability to efficiently dissipate power. A wirewound resistor is an electrical passive device that limits or restricts current flow in a circuit. Definition of a wirewound resistor a wire wound resistor is a resistor where a wire with a high resistivity is wrapped around an insulating core to provide the resistance.

Aluminum housed wirewound resistor with silver colour 07 06 2013. Retroarcade us 040293115579 25 ohm 3 watt rheostat 5 tolerance wirewound variable resistor potentiometer 6 95 6. What are wirewound power resistors. In general it is true that wirewound resistors fulfill the requirement of producing lower resistance values in the end.

The parameters of the wirewound resistor such as the resistivity of the wire in use can be tightly controlled. Example of a wire wound resistor construction. Ceramic encased wire wound resistor.
