In some industries it is called "heat trace cable". Several sources including
this one have it available in shorter lengths and/or by the foot by using
appropriate terminals. It is also available in a 12/24V DC configurations.

Subject: [TowerTalk] Heat tape for relays
I have a lot of relays in this station, and many are outdoors (in enclosures).
Over the last few years it has become apparent that the occasional super cold
nights are making some of them flakey. They stick -- if I go out with a
hairdryer I can free them up.
These are enclosed relays.
I am wondering if anyone has ever tried using heat tape for this kind of
application? I could just flip it on when I needed it. Most heat tape I see
is for water pipes and is 6 feet long or so. I could try to use this, but what
I really need is something smaller and possibly flatter.
Any ideas? Thanks.
