Insulators & Insulation Materials

Insulators are materials that resist the flow of electric current, playing a crucial role in electrical systems.

Types of Insulators

• Post Insulators - Compact design for voltages up to 115 kV
• Pin Insulators, used for voltages up to 33 kV, mounted on cross-arms
• Shackle Insulators, used for low-voltage distribution, can be mounted horizontally or vertically
• Strain Insulators, designed to withstand mechanical tension, used in overhead wiring
• Suspension Insulators, used for voltages above 33 kV, consist of multiple discs in series

Insulation Materials

• Mineral wool - made from recycled materials, and also is afire-resistant
• Fiberglass - excellent thermal and acoustic insulation
• Natural fibers - Eco-friendly options like cotton or sheep's wool
• Cellulose - Made from recycled paper products, treated for fire resistance
• Polyisocyanurate - High R-value per inch and is suitable for limited spaces
• Polystyrene - Available in expanded (EPS) or extruded (XPS) forms
• Polyurethane - High insulation value, can be sprayed or used in rigid boards
• Perlite - Lightweight volcanic glass and is suitable for high-temperature applications
• Phenolic foam - High fire resistance and low smoke emission
• Cementitious foam - Non-combustible, used in structural applications
