Is Technical Petroleum Jelly (Vaseline) an Electrical Insulator or Conductor?

Hello.
From what I remember petroleum jelly is a cousin of paraffin so it is an insulator. Its role in electrical connections is to prevent oxidation of these connections and thus reduce their resistance.
V541 is right.

And like a fool in flip-flops in the middle of the night I rushed to the workshop for a can of Vaseline. I put the probes with the MIC-2500 and on all ranges it showed that the measurement was out of range (that it was supposed to be perfect). So I don't know anymore.

... there are no literal insulators, because any material will eventually pass current (it's just a matter of voltage).

... But when we cover the ends of the wires with a layer of petroleum jelly and touch them, the current will flow. It's probably a poor insulator.

To please both parties - a semiconductor

Yes, but since, according to Łukasz-O, petroleum jelly is a semiconductor, it should be stated whether it is intrinsic or doped, and what goes on with the acceptor or donor admixture and the second thing is whether petroleum jelly is a semiconductor - with a straight energy gap or with an oblique energy gap, I think , that it cannot be left unanswered in the face of such a bold hypothesis put forward by Col. Łukasz-O which may be, first of all, meeting the need to provide a correct and exhaustive answer to the fundamental question.

Hello
In my opinion, it's like water, chemically pure, it doesn't conduct, only where to get it, and ordinary tap water conducts and don't check it because I touched such "strange water" and potelepała that hey.
