Like the United States, The United Kingdom was a very early adopter of the Telegraph and
therefore needing insulators in the mid 19th century. Almost from the
start, porcelain was the preferred material for these insulators. This may
have been due to porcelain's better performance in the damp English climate or
simply the availability of quality potteries. Very few glass insulators
were made or used in the UK. These insulators are identified by U-numbers, but in the range
of 1000-3999. The link below is for the reference book that covers these
insulators.
