U Number Overall Listing

This section provides the U numbers representing unipart pintype porcelain insulators from outside the United States.  Note that U-100 to U-999 represent insulators manufactured in the United States.  Numbers from U-1000 to U-3999 are assigned to the unipart pintype porcelain insulators from any other country.  The exception are insulators made outside the united states that match US styles - these will retain their sub U-1000 number.  The listing below does not differentiate by country - if that is desired see Country listings.
