Well that was 30+ years, a direct lightning strike, and two kids ago and the transformer is still going strong. It will probably still be there after I'm in the ground.
And full of PCB's... -- Need-based health care not greed-based health care.
The transformer was installed in 1980 when we first moved onto the property. This was around the time of the big PCB scare. I was assured the transformer did not contain PCB. Utilities were going through a big replacement phase at the time so I have no reason to doubt the accuracy of that statement.
In the US manufacture of PCBs was banned in 1980. According the the EPA PCB use in transformers ended in 1977.
