Insulating Materials for Electrical Wires
Electrical wires require insulation to prevent unintended electrical conduction and ensure safety. The insulating material used must possess certain characteristics, making PVC the most suitable choice.
Characteristics of Insulating Materials
- Electrical Resistance: Insulating materials must have high electrical resistance to prevent current leakage.
- Thermal Stability: They should withstand a range of temperatures without degrading.
- Chemical Resistance: Insulators must resist various chemicals to maintain integrity over time.
Why PVC is Preferred
- Cost-Effective: PVC (Polyvinyl Chloride) is inexpensive to produce, making it accessible for widespread use in electrical applications.
- Durability: PVC is resistant to moisture, chemicals, and UV light, enhancing its longevity.
- Flexibility: The flexibility of PVC allows for easier installation of wires in various configurations.
Other Materials Considered
- Sulphur: While sulphur has insulating properties, it is not used for electrical wire insulation due to its brittleness and low durability.
- Graphite: Graphite is a conductor rather than an insulator. Its use in electrical applications is typically limited to conductive materials rather than insulation.
Conclusion
In summary, PVC stands out as the ideal choice for insulating electrical wires due to its excellent electrical resistance, durability, and cost-effectiveness. Other materials like sulphur and graphite are unsuitable for this purpose, confirming that the correct answer is option 'C'.
