Insulators are materials used to prevent the passage of electricity or heat, serving critical roles in both electrical and thermal applications[8].
Electrical insulators are widely used to:
- Prevent unintended current flow in electrical and electronic equipment, reducing risks of damage and hazards[1].
- Support and insulate overhead power lines and components in substations to ensure safe and reliable electricity distribution[2].
- Manufacture motors, cables, transformers, and virtually all electronic devices to keep conductive components safely separated[4].
- Protect and insulate wire and cable in various industries—medical, military, automotive, and consumer electronics—ensuring durable and safe connections[7].
- Enable signal integrity in telecommunications infrastructure by protecting fiber optic cables and antenna systems[2].
Thermal insulators are used to:
- Minimize heat transfer in buildings (insulation boards, foams, fiberglass) for energy savings and comfort[5].
- Protect industrial equipment, such as boilers and furnaces, by slowing heat loss and shielding nearby components[3].
- Maintain temperature stability in specialized fields, including automotive engine compartments, spacecraft, and refrigeration systems[3].
Modern insulators, including advanced plastics, composites, nanomaterials, and specialty coatings, continue to expand capabilities in miniaturized electronics, data centers, electric vehicles, and high-performance manufacturing[1].
