 | In the new pole assembly area, the
core/coil assembly is mated to a tank which has been prepped with ground lugs, and decals. The interior assembly is then completed and all thru tank wall components are affixed and connected. Each transformer is then individually vacuumed (to complete the drying process) and filled with de-gassed high dielectric strength oil. The transformer remains under vacuum while the unit is filled with oil so as to ensure that all of the air and moisture are removed.
Upon complete interior assembly, the cover-retaining band provides even gasket compression plus conforms to ANSI requirements for a venting cover design. High voltage bushings are made of a strong wet process porcelain. The low voltage bushings utilize a polymer housing. Terminals are plated for compatibility with copper and aluminum leads. | |
