Product Description
Custom Industrial High Voltage Al2O3 Alumina Steatite Electrical Ceramic Insulator Tube
 

Product Introduction

With our machining and manufacturing capabilities, Jinghui Ceramics can offer a wide range of standard and customized alumina ceramic insulator tubes. They are regularly made from high-purity aluminum oxides such as 95%, 99%, 99.5% and 99.8% depending on the applications in the different fields. In order to cater the precise fitting relationship, some secondary processes have to be conducted at-house, including fine grinding, drilling, tapping and CNC machining. Therefore, we can meet various technical specifications and grades of ceramic tubes in the market to achieve customers' demanding needs. 

Aluminum oxide (Alumina) has an extensive application due to its versatility and low cost of material than other advanced ceramics. Alumina offers high electrical insulation resistance, high-temperature resistance, strong hardness, wear resistance, and good chemical stability. This makes it an ideal material choice for applications requiring high temperature and corrosion resistance.
