subject: Which Properties Make Wire Enamels Useful For High-end Applications? [print this page] Wire enamels are the liquid resins that are used to coat wires, usually of copper, to enhance their utility in different applications. The wires coated with rubber are not suitable for some applications that require wire insulation. Rubber can be easily replaced by different varieties of enamels so that the insulation wires become more useful. Here are some applications that make use of enameled wires:
The transformers use enameled wires to step up or step down the power supplied.
Enameled wires are used by the motors to convert electrical energy to mechanical energy.
Mechanical energy is transformed into electrical energy using generators that again make use of enameled wires.
So, what are the properties of wire enamels that make them eligible for the above-mentioned applications and other purposes? Learn about these properties from the following discussion.
Less Space Required
Normal wires with thick rubber coating take up more space when used as coils in the devices like transformers and motors. This ultimately increases the overall size of these devices. However, the enameled wires dont require much space due to thin coating offered by polyester wire enamels and other types of enamels.
Mechanical Strength
Enameled wires possess strength to withstand extreme mechanical force during the operations like conversion of one form of energy to another. For example, the polyurethane wire enamels are designed to protect wire against wear and tear. So, one can expect long life for the enameled wires.
Temperature Withstanding Power
Different type of wire enamels have high temperature withstanding power and are therefore suitable for the applications like those mentioned in the beginning. As such applications deal with high temperature and excess heat conditions; you can rely upon enameled wires for good performance.
Protection against Corrosion
Wires made of certain metals are less resistive to corrosion. However, coating them with different types of enamels solve the problem as these enamels produce resistance to corrosion. This makes the use of enameled wires possible in different types of working conditions.
Advantage to Soldering
Finally, the enamels like polyester and polyesterimide wire enamels offer advantage of responding well during soldering. These enamels act as flux when burnt during the process of soldering. Unlike normal wires, the enameled wires dont require to be sandpapered or scraped before soldering.
Wire enamels are the most preferred wire insulation materials due to the above mentioned properties. These enamels significantly contribute towards the long-term usability of the electrical devices.
