Cylindrical ceramic insulator

Q: Are you looking for an electrical insulation solution that can maintain stable performance even in high voltage, high temperature, or harsh environments?
Q: Are you concerned about equipment failure or safety hazards caused by aging, creepage, or mechanical stress on insulation components?
Q: Do you need an insulation product that can be customized in size, has strong adaptability, and has a long service life?
Answer: Cylindrical ceramic insulators are designed to solve these problems. It is widely used in power, electronics, rail transit, and industrial equipment due to its excellent insulation, mechanical strength, and weather resistance, effectively ensuring the safe and stable operation of the system.

Cylindrical ceramic insulator is a cylindrical insulating component made from high aluminum oxide or high-purity industrial ceramics through high-temperature sintering. Its design structure is simple and the geometric shape is uniform, suitable for various scenarios that require electrical isolation, mechanical support, or environmental protection. The product has high dielectric strength, low loss factor, excellent thermal stability, and chemical corrosion resistance, making it an ideal substitute for traditional plastic or composite insulation components.

Core strengths

1. Excellent electrical performance
   -High insulation strength (up to 20-40 kV/cm), effectively preventing arc and creepage phenomena.
   -Low dielectric loss, able to maintain stable capacitance characteristics in high-frequency or high-voltage electric fields.
2. Excellent mechanical and thermal stability
   -High compressive strength (up to 1000 MPa or more), wear-resistant, and not easily deformed.
   -Wide working temperature range (-50 ℃ to+500 ℃), heat-resistant and shock resistant, suitable for high temperature environments.
3. Strong environmental adaptability
   -UV resistant, acid and alkali resistant, anti-aging, suitable for long-term use in outdoor or chemical environment.
   -The surface is smooth and dense, not easy to accumulate dirt, and can reduce maintenance frequency.
4. Long lifespan and reliability
   -Ceramic materials have no aging or creep, and their service life can reach decades, reducing replacement costs.
