Heat resistant flex 3183TQ vs 3093Y

[ringer]

What is the difference between these two specs for heat resistant flex? Have to fit some in a chip shop and not sure which to go for.

All i can see is ones flame retardant and resistant to oil and grease sounds like the one to use

Thanks for that Nick. Unfortunately I am non the wiser because I am unable to discern the difference (apart from 85 degs vs 90 degs) and I am not conversant with the british standards quoted.The application is in a chip shop, and the heat it has to resist comes from outside the cable, not necessarily due to large currents flowing through the cables. 3093Y seems to be significantly cheaper which makes me rather doubtful as to its suitability. Any suggestions as to which one I should select?

Does it have to be flexible or is it to be permernantly fixed ,what are you using it for

 

[ringer]

To be honest, am not sure yet - am just going on say so of shop owner. Planning on going round soon (may get free bag of chips!) to check it out. Just wanted to be genned up on technical specs so I can best assess what is needed.

Looks like 3183TQ would be best - rubber/butyl outer and resistant to oil & grease (which will likely be there is spades in this environment)
Am guessing 3093Y is more appropriate for lighting applications and have seen a description 'unsuitable for industrial environments'.

 

[nickblake]

the reason i asked is if they are going to be permanantly fixed why not use FP200 or a mains rated flame retardent cable ,but out of the youve quoted id use the 3183TQ as its resistant to oil and grease as well as 85 degree and chip shops are full of grease

Just been to look - it is not heat damage but rodent damage. The critters got a 10mm earth as well as the 3-core flex.

 

[nickblake]

yes i had that problem grrrr so id just go for the 85 deg cable then job done

Nick, are you saying that heat-protection covering (butyl) gives rodent protection? Thought I might need swa. Not sure how to protect the 10mm earth though.

Just had a thought, I may be able to route them out of harms way. If so then no special protection reqd. Will have to work out how to support cables as they are within a (hot) metal enclosure. Drilling is out ,so is adhesives. Guess I could spot weld them

ITs a food service area they should not have rodents , well the little squirrel attack i had , i had to replace all the wiring and the whole lot was re done with SWA and also installed two ultra sonic rodent reppelants
