🔍 Introduction
Electrical insulating materials play a critical role in ensuring safety and efficiency in electrical systems. These materials prevent unwanted electricity flow, reducing the risk of short circuits, equipment damage, and electrical hazards. From industrial applications to household wiring, insulation is essential for reliable and secure electrical operations.
💡 What Are Electrical Insulating Materials?
Electrical insulating materials are substances that resist the flow of electric current, ensuring that electricity remains confined to its intended path. These materials are used to isolate conductive components, preventing accidental contact and minimizing energy loss.
🎯 Key Characteristics of Good Insulating Materials
✅ High Electrical Resistance – Prevents current leakage.
✅ Strong Dielectric Strength – Withstands high voltage without breakdown.
