Definition of insulator An insulator is a component used to isolate the conductive part of electrical equipment from the ground or other equipment. It has good electrical insulation performance, can effectively prevent the occurrence of current leakage and short circuit and other faults, to ensure the normal operation of the power system. Insulators are usually made of ceramic, glass, rubber, plastic and other materials, with excellent insulation and mechanical properties.
Types of insulators According to different uses and working environments, insulators can be divided into many types. Common insulators include:
1. Ceramic insulators: mainly used in high-voltage transmission lines and substations in power systems, with good insulation properties and mechanical strength.
2. Glass insulators: mainly used in optical fiber communication and sensors and other fields, with excellent optical and electrical properties.
3. Rubber insulators: mainly used in electrical equipment such as motors, electrical appliances, cables, etc., with good elasticity and oil resistance.
4. Plastic insulator: mainly used in electronic equipment and communication equipment, has the advantages of light, easy processing and low cost.
