Re: [RFI] Fwd: A `Time Bomb' Sits Atop 30, 000 Utility Poles In State

Thanks, Tom - interesting piece.  Our HV distribution here is 7500V, so our 
cutouts may not be the same series, but it strikes me as worth asking.

Also, this may belong on Towertalk, but this procelain cracking phenomenon is 
far from confined to powerline insulators.  I installed the jonny-ball 
insulators on my bottom set of guys upside down, so that the unglazed surface 
is up.  Recently I noticed that all the insulators are only part 
there,evidently as a result of freeze-thaw cycles and water in the porcelain.

73, Pete
