Re[2]: Capacitor oil

     Hi all, With regard to capacitor oil, I would suggest an oil 
     specifically designed for high voltage operation. Here at BICC 
     Supertension Cables, we use C14B oil in paper insulated cables rated 
     up to 500KV. We also use a wax which is impregnated into the cable at 
     about 120 degrees. The oil is definitely safe to use on polypropylene 
     as this is a component in the cable. I would assume tentatively that 
     it would be ok on polythene as well.
       I could dig out details of C14B oil if people are interested, but I 
     would think its a bit special and quite hard to get hold of in small 
     quantities. Failing that a commercial transformer oil made by Shell 
     or equivalent should be the best bet. I scavenged some oil from a HV 
     transformer used in corona treatment which I have stored ready to use 
     in a cap sometime. Watch out for PCB's in older kit, you don't want 
     to be changing sex inadvertently.

In addition how about hydraulic fluid? The oils 
should have the water 'baked' out. Has someone 
done this?
