Ceramic post insulators

Ceramic post insulators are one main of high voltage ceramic insulators for electrical systems and electrical equipment and made from unique vertical integration raw material.

Ceramic post insulators

The ceramic post insulators manufacturing process
◆ Selection of raw materials
◆ The insulator materials are of high purity and with constant properties
◆ The optimized mix is mixed and ground exactly in accordance with the formulation
◆ These Vacuum extrusion presses then shape the plastic filter cakes into cylindrical blanks, the so-called "bodies"
◆ A precisely defined drying process
◆ Glazing in colors, such as blue, grey and brown
◆ Insulator testing

After a precisely defined drying process, Ceramic post insulators already have high strength for clay bonding. During the insulator glazing, Ceramic post insulators shall be coated the RTV silicone rubber coatings applied in the immersion bath.

During the subsequent firing, Ceramic post insulators have high hardness is created. Ceramic post insulators have more good performance and properties.
