Usually FRLS [Fire Resistance Low Smoke] material it is used for jacket and less for insulation. But for general properties see:

FRLS is the insulation property(Type of cable) and XLPE is the Insulation..FRLS Cables available with XLPE Insulation..

Why do your own homework when someone just gives you the answer?

As I have stated a billion times, it doesn't help the lazy student or incompetent worker very much to give them the answer to the immediate question.

Unfortunately, the student/worker only learns how to get others to do their work for them.

That's OK if the student is studying to be a manager, I guess. Unfortunately, engineers are expected to DO THEIR OWN WORK!

Cheers. Enjoying retirement?

I agree with you, lyn, an engineer has to be independent and to approach any issue by his own means: knowledge, books and other.

First of all[for instance] you could get MS in Design and Engineering of Electrical Machine and you get a job in Power Station Operation. You have some general knowledge, but it is not enough.

You have the sensation of getting drowning - mostly. Second: English could not be your mother tongue. May be?

7anoter4,

If you go to any member's profile page you can view all the past posts of that member.

If one goes to Saminathan's profile page one will discover that all their questions are elementary and questions that someone with an education should already know, or know how to find.

Your profile, on the other hand reveals that you are intelligent, provide competent technical help and never ask questions that could be easily researched.

Saminathan should be more like you.

Having seen all manner of rudimentary questions coming from posters (I've been here for awhile) who claim to be engineers, or even graduate engineers, I have very little tolerance for providing information which should have been gleaned from classwork and studies.

Now it seems to me, also, that Saminathan tries to keep people busy by asking not specific questions of general engineering knowledge. Thank you, lyn.

FRLS Cables ( Flame Retardant Low Smoke Cables) are manufactured for use in special premises where there is risk of human life due to smoke from electrical fire. They are made out of special insulation which prevents smoke from the burning of insulation. The cable is mostly used for the wiring of Cinima halls, Multiplexs, Airports etc. refer IEC 6052 1 &3

XLPE Cable ( Cross Link Poliethelene ) is a cable insulation replacing PILC and PVC cables due to its better temperature withstanding qualities and long life. XLPE cable can also be manufactured to be FRLS.
You can get all the details about cables from most of the cable manufactures. Spend a little time and effort to read the subject rather than putting up a thread here. Lot of reading materls are available by simple google search.

...so <...XPLE...> is a subset of <...FRLS...>, therefore the concept of <...advantages and disadvantages...> of one over the other is actually meaningless.

Cables-mainly low voltage cables-are insulated with PVC as THHN or XLPE as XHHN. Both-according UL 44 for XLPE Thermoset-Insulated Wires and
Cables and UL 83 for Thermoplastic-Insulated Wires and Cables [PVC], may be flame retardant and smoke limited if they withstand the tests-according to UL 1685.

However, since the raw material and the test are expensive if is not necessarily, a customer may not require that.
