As a precison ceramic insulator manufactures, we can produce all of sizes and types of the ceramic insulator with advance ceramic raws(A variety of ceramic materials are available).High Purity Alumina is an exceptional material for electrical insulation or isolation requirements, particularly compared with currently used conventional ceramics such as steatite and porcelain.


Electrical Properties

In terms of electrical properties, Ultra High Purity Alumina compared to steatite or porcelain has:

  • A 2.6 times lower loss factor Tan δ – too high a tan δ can lead to excessive heating brought about by the incoming active power and thus to a shorter life time of the insulator
  • A Dielectric Constant of approx 1.6 times higher than Steatite – the dielectric constant affects how electronic signals move through the material; a high dielectric constant means this energy travels more slowly through the material
  • Higher Dielectric Strength – the value at which the insulator, when placed in an electric field will lose its insulating properties if the field exceeds a certain critical value
  • A lower Dielectric Loss – the proportion of energy lost as heat; the lower the dielectric loss the more effective the insulator

Operating Environments

Ultra High Purity Alumina is also suitable for higher temperature applications and generally has a limit of operation up to 1600°C. This, coupled with a high corrosion resistance makes it ideal for insulators, particularly those found in electrostatic precipitators which usually have operating conditions of high temperature, humidity and acid or alkaline conditions.
