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
