Introduction:

Copper wires are widely used for electrical fittings due to their unique properties and advantages. Let's explore the reasons in detail.

1. Conductivity:
Copper is an excellent conductor of electricity. It has a high electrical conductivity, second only to silver. This property allows electricity to flow easily through copper wires, minimizing energy loss and ensuring efficient transmission of electrical power.

2. Low Resistance:
Copper has low electrical resistance, which means it offers less opposition to the flow of electric current. This characteristic reduces the power loss in the form of heat during transmission. Low resistance also helps in maintaining the voltage levels over long distances.

3. Ductility:
Copper is highly ductile, meaning it can be easily drawn into thin wires without breaking. This property allows the production of thin and flexible copper wires, which can be used for various electrical applications, including wiring circuits, electrical motors, transformers, etc.

4. Heat Resistance:
Copper wires have good heat resistance, which makes them suitable for applications where heat is generated, such as in electrical motors or high-power circuits. Copper can withstand high temperatures without significant degradation in its electrical properties.

5. Corrosion Resistance:
Copper is resistant to corrosion, making it suitable for long-term use in electrical fittings. This property ensures that the copper wires maintain their conductivity and performance over an extended period, even when exposed to moisture or harsh environments.

6. Cost-effectiveness:
Copper is relatively abundant and cost-effective compared to other conductive materials like silver or gold. This makes copper wires an economical choice for electrical fittings, ensuring affordability without compromising on performance.

7. Compatibility:
Copper wires are compatible with various insulation materials commonly used in electrical fittings. They can be easily combined with insulating materials like PVC or rubber to provide electrical safety and protection.

Conclusion:
Copper wires are widely used for electrical fittings due to their excellent conductivity, low resistance, ductility, heat resistance, corrosion resistance, cost-effectiveness, and compatibility with insulation materials. These properties make copper an ideal choice for electrical applications, ensuring efficient transmission of electricity while maintaining durability and safety.

Copper wires are used as a conductive wire as it is a good conductor of electricity. Of course Ag, (Silver) is the best conductor of heat and electricity but it can't be used because it is very costly.
