Heat resistant tape recommendation please

[JBrennand]

I had to replace the grill element on the oven today and noticed that the wiring was a little "scorched" (see photo) presumably by contacting the heat pipe going up. Its not damaged or perished but its a bit disconcerting. I would like to shield the wiring before reinstating.
What would you suggest using ? Oven typically operates up to 220 deg C.
I have silicon rubber tubing (from a lab) that might work but I am guessing a heat resistant tape might be better - any recommendations or alternatives please.
Thanks John

It probably is.

Something to keep the wiring from touching that pipe, for example a strip of SRBP fixed to terry clips.

Oven typically operates up to 220 deg C.

And typically the insulation on cables like those is not expected to be used on cables operating at > 70°C.

AFAIK, "heat resisting" tapes are designed to resist the effects of heat on themselves, i.e. to not get damaged, have the glue fail, etc, not to act as thermal insulation.

What about wrapping the pipe in glass fibre thermal tape - similar to this one.

I'd be quite surprised if that turned out to be ordinary 70°C PVC wiring. Given the application and the appearance of the wiring I would expect it to be 180°C SIF

How old is it?
Maybe ask the manufacturer for advice. I'd worry that those wires are already damaged.
