High Voltage Resistant Round Enameled 42 AWG Copper Wire is an insulated covered fine copper wire typically used in high voltage applications.

Available in High Voltage Resistant Round Enameled 42 AWG Copper Wire is typically used in applications where high voltages need to be withstood. These applications may include high frequency electronics, transformers, inductors, circuit boards, and other electrical equipment that needs to be thin and resistant to high voltage.

42 AWG copper wire is a very fine gauge wire and therefore has a high resistance. The amount of resistance depends on the length and cross-sectional area of the copper wire. Higher resistance may result in power loss and heat generation in the line.


High voltage resistant round enameled 42 AWG copper wire is usually insulated with Polyamide-imide or other high temperature insulating materials. These materials have good heat and voltage resistance properties and provide effective electrical insulation protection.

The voltage resistance of high-voltage round enameled 42 AWG copper wire depends on the material and thickness of the insulation. The insulation must be thick enough to prevent electrical breakdown and leakage. When designing and selecting copper wire, the proper level of insulation needs to be determined based on the voltage requirements and safety standards of the application.

Since 42 AWG copper wire is very fine, its current carrying capacity is limited. Therefore, when designing a circuit, you need to ensure that the current does not exceed the rated capacity of this copper wire to avoid overheating and damage. In addition, due to the small wire diameter, 42 AWG copper wire has low mechanical strength and may not be suitable for applications requiring high mechanical strength.

When using high voltage resistant round enameled 42 AWG copper wire, applicable electrical safety standards and codes need to be followed. These standards ensure the safety, reliability, and regulatory compliance of electrical equipment.

For specific applications, it is recommended that you consult with a circuit designer, electrical engineer, or professional electronics engineer. They can provide more detailed and accurate recommendations based on your specific needs and application environment to ensure that the copper wire selected meets the requirements and ensures the safety and performance of your equipment.
