(OP)
We have a 480V oil pump immersed into ATF (automatic transmission fluid). Pump vendor extended motor leads
using compression type butt splice with insulating sleeve
over the splice. Can we have any problems with that since
ATF would penetrate to conductors? May be there is a regulation which would require to use heat shrink tubing
on immersed wire splices? Please advise.

can they not use a liquid tight flex conduit and do the butt splice inside?..i am referring to the workmanship not taking the code in consideration yet..

You should have a liquid-tight seal or solder or something that will not allow any liquid penetration. There was a posting a couple of months ago about a DC brushed motor submersed in some sort of oil and the problems it had with maintaining contact.

Ask the vender if he used an epoxy filled heat shrink. This would give an excellent seal at the splice.

Something besides a common sense,and to prove the vendor
that he did a poor job which should be reworked in a proper
way.

if you want to get really mean...let them run new wire spliced right at pump motor termination box ( oil tight) then use oil resistant cable or liquid tight flex conduit going to the control station ( dry)...

It is very easy to screw up the splice and get a blown cable. I have never dealt with tranny fluid in this manner so I would verify with the wire mfg that they approve of submersion in tranny fluid, especially if you suspect an unqualified "vendor". Good luck.

For fluid-immersed motors using either built-up or 'kit' cable splicing, routine installation expense by competents can typically be a small fraction of repeat rigging and repair effort, aside from production-loss considerations.
