Single Phase and Three Phase


Product Scope & Ratings:

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.
