24kV To 36kV HV Porcelain Transformer Bushing

High Voltage Transformer Bushings

Product Overview

A high voltage porcelain transformer bushing covering the 24 kV to 36 kV band. Inside the transformer it insulates the leading wires from each other and from other conducting surfaces, which is what prevents short circuits at these voltages. It also provides mechanical support, holding the wires in position so they cannot move into contact. Ceramic offers the dielectric properties that keep insulation reliable under extreme voltage conditions.

Key benefits

Comparison

How It Compares

Glass insulator materialsBoth ceramic and glass offer excellent dielectric properties. Ceramic is the established choice for transformer bushings because of its mechanical behaviour at the tank interface.
DIN and EN pattern bushingsThose carry fixed dimensional and test values per standard. This listing covers the voltage band, so confirm the pattern your transformer drawing requires.
Use guide

Before You Order And After It Arrives

  • Confirm which voltage class within the band your transformer needs
  • Send the terminal board drawing so the pattern can be matched
  • Keep the leading wire clearances as the design intends
  • Inspect the bushing surface at every transformer service
Questions

24kV To 36kV HV Porcelain Transformer Bushing Questions

What voltage range does this bushing cover?
24 kV to 36 kV.
What does the bushing do inside the transformer?
It insulates the leading wires from each other and from other conducting surfaces to prevent short circuits, and it provides mechanical support that holds the wires in place.
Why ceramic rather than another material?
Ceramic offers the dielectric properties needed for reliable insulation under extreme voltage conditions, along with the mechanical strength required at the tank interface.
Which exact pattern will I receive?
Send the transformer terminal board drawing and we will confirm the pattern and dimensions before production.
Do you make DIN and EN patterns in this range?
Yes, including DIN 42531 and EN 50180 bushings at 24 kV and 36 kV.
Can you produce to a sample?
Yes, we produce to customer drawings and samples.
