Ceramic insulator, also known as ceramic insulator, is an insulation device used in power transmission lines and electrical equipment. Its main function is to support wires and prevent current from returning to ground. They are usually made of ceramic materials, with high insulation strength, good mechanical properties, and weather resistance, and can operate stably in various complex environments. The main characteristics and advantages of porcelain insulators:High insulation strength:Ceramic insulators have high dielectric strength and can effectively prevent current from passing through, ensuring the safety of power transmission. Good mechanical performance:Ceramic insulators can withstand the weight of wires and various mechanical stresses, such as wind force, ice and snow, ensuring the stable operation of the line. Excellent weather resistance:Ceramic insulators have good weather resistance and corrosion resistance, and can be used for a long time in various harsh outdoor environments. Wide range of applications:Ceramic insulators are widely used in high-voltage transmission lines, substations, electrical equipment, etc., and are an important component of the power system. Classification of porcelain insulators:According to structure, it can be divided into suspension insulators, rod insulators, pillar insulators, etc.According to voltage level, insulators can be divided into different voltage levels such as low voltage, high voltage, and ultra-high voltage.According to the usage environment, insulators can be divided into ordinary and pollution resistant types. Pollution resistant insulators are suitable for areas with severe pollution. The main applications of porcelain insulators are:Overhead transmission lines:Ceramic insulators are used to support wires and prevent current from returning to ground, and are an essential part of overhead transmission lines. Substation:Ceramic insulators are used to support busbars, isolating switches, and other equipment to ensure the safe operation of substations. Electrical equipment:Ceramic insulators are used for insulation of various high-voltage electrical equipment, such as transformers, circuit breakers, etc.
