RE: GE Type U power transformer bushings
The most well known problem with these bushings is the Rescon ink that was used as the capacitive layers to form the core. There are many problem with this design ranging from the ink, paper thickness, top can cover design etc...Mostly the problems lead to increasing power factor which leads to failure.
The Rescon ink core was not only used in type U bushings but also some type T's.
You can have these bushings repaired by a bushing manufacturer where a new core design will replace the troubled Rescon ink design. Both PCORE Electric and ABB offer repair services and are original equipment manufacturers of bushings.
As the above poster mentioned contacting Doble Engineering or ABB I am sure will provide you with some quick information.
