[0001] The utility model relates to the technical field of nitrogen oxide ceramic rods, and particularly relates to a reinforcing structure for a nitrogen oxide ceramic rod. Background Technique

[0002] A nitrogen oxide ceramic rod is a ceramic material product with special properties. High strength: Nitrogen oxide ceramic rods usually have relatively high mechanical strength and can withstand a certain amount of pressure and tension, performing well in some application scenarios with high material strength requirements. High temperature resistance: It has good high-temperature resistance and can maintain stable physical and chemical properties in high-temperature environments, being suitable for high-temperature industrial fields. Corrosion resistance: It has strong resistance to many corrosive media and is not easily corroded by acids, alkalis, salts, etc., extending the service life. Good insulation performance: It can be used as an electrical insulation material to ensure safe operation in electrical equipment.
