Submersible Single Phase and Three Phase Transformers Brochure

VanTran manufactures a full line of single and three phase submersible transformers for vault applications. Our submersibles feature 304, 316, or mild steel tanks with welded on covers and a heavy tar-like coating to prevent corrosion. High voltage bushings are top mounted, dead front, epoxy wells with inserts. Low voltage bushings are also top  mounted and come standard with spade terminals. Fusing is accomplished by under oil non-load break canister fuses interlocked to an on-off switch for safety.  VanTran custom makes all of our submersible radiators out of 3/16” steel plate to ensure our units will withstand the challenging, high moisture environments inherent to vault installations. These units are available in sizes up to 2,500 kVA and 150 kV BIL.
