Would this be a possible substitute for fiberglass sleaved fixture whips? Temperature Control Cable: SRG-S
Possibly and I do mean that. By the way vinyl coated fiberglass sleeving stands up to more abuse than normal fiberglss sleeving in high abuse situations.
There is also some in addition to silicone coated cable on the market that in general is a little less resistant to chemicals in the air such as DF-50 fluid or abuse in general such as a thumb nail cutting thru it, other types on the market with vinyl coated sleeving much like SJ cable but 200c heat resistant. This in addition to a sort of like varnish coated fiberglass sleeved solid in filler heat wire on the market which is solid in being bullet proof.
Problem with the above cable as with others is in strand count of the conductors. Sure I could go with a 250c heat wire for instance, but there is less strands of conductor in having larger strands per wire size that are less flexible. That flexibility is just as much a problem as outer jacket failing in the end. Ain't flexible enough and it's like having a solid wire within your whip in that it will flex for a while but break later in use.
Sent a copy to work in being interested but for the most part my first thoughts of concern on such a cable would be on stranding of the individual conductors in it being flexible for constant service as opposed to perminant non-moving install.
Could be great but I have spools of "coluld be great" heat wire cables that were not flexible. TMB has some good heat wire on the market but after that since Rockbestos has been discontinued, not much else out there I know of given a specific very popular brand not mentioned due to the above resistance to chemicals or nicking.
About the flexibility verses resistance. SF-2 200c heat wire is good and fine, it in a vinyl coated fiberglass sleeve is also a good improvement. After that, I'm still play testing myself but found the TMB products so far good. One silicone coated but a different more resistant silicone, and the other a more like Rockbestos like heat wire within a high-temp and resistant vinyl sleeve to be useful, but also flexible for cord whip.
