Types of electrical insulators & their uses: Electrical insulators are essential components in power generation, transmission, and distribution systems. They support energized conductors, prevent unwanted current leakage, and provide electrical isolation between live components and grounded structures.  Insulators are manufactured from materials such as porcelain, glass, and polymer composites, with their design selected according to voltage level, mechanical loading, environmental conditions, and installation requirements. ⚡ 1. Disc insulator Uses: Disc insulators are connected in strings to support overhead transmission conductors at medium and high voltages. Additional discs can be added to meet the required insulation level for different voltage classes. 🔌 2. Pin insulator Uses: Pin insulators support conductors on poles using a pin or spindle arrangement. They are commonly used in overhead distribution networks, particularly at lower and medium distribution vo...
