Oil Filled Transformer Porcelain Ceramic Bushings

Description

Porcelain Transformer bushing / Insulator  For voltages of approximately Um ≤ 36 kV, a simple dry type
bushing is commonly used. Dry bushings consist of a conductor
surrounded by a high-grade porcelain insulator body. ‘Dry’
indicates that no insulating fluid is used in the bushing
construction. The porcelain body surrounds the entire conductor
except for the terminal ends.   
For higher distribution voltages, Um ≤ 52 kV, electrical grade
mineral oil is often used as part of the insulating structure to
increase the electrical withstand capabilities of the bushing. In
order to achieve this, a void (empty space) is created during the
bushing’s manufacture and oil then fills the space between the
conductor and insulator (porcelain body).  
Variations in oil filled bulk type bushings include:  

• Oil shared with the transformer main tank:
• Oil that is sealed within the bushing.
• Oil that can be accessed through the bushing body (this allows for easy oil replenishment, or, oil sampling with dissolved gas in oil analysis (DGA) diagnostics etc., but is no longer favoured because of contamination concerns).
