Porcelain Insulators For Distribution Transformer Manufacturers
Terminal boards designed around one bushing pattern that the original supplier has discontinued
What Gets In The Way
- Terminal boards designed around one bushing pattern that the original supplier has discontinued
- Bushings arriving without the gaskets, connectors and fasteners needed to complete the assembly
- Tank holes cut to a drawing before the bushing dimensions were confirmed
- Separate suppliers for the HV and LV side of the same transformer
What This Sector Needs From A Supplier
- Both DIN and EN patterns held in production rather than one or the other
- Published tank hole size and stem thread against each current rating
- Complete assemblies including NBR gaskets and stainless steel fasteners
- Production to drawing when the pattern is not catalogued

Product Families To Start From
High Voltage Transformer Bushings
Bushings for the high voltage side of distribution and power transformers, from the 10kV class up to 36kV.
Low Voltage Transformer Bushings
Bushings for the 1kV and 3kV winding side of distribution transformers, from 250A up to 4000A.
Screw Thread Transformer Bushings
Bushings whose threaded stem takes the terminal connection directly, the arrangement used on ANSI terminal boards and smaller pole transformers.
Where These Parts End Up
- Oil-immersed distribution transformers from 10kVA to several MVA
