Is Prysmian LSX a suitable replacement for armoured cable

Alan B

LSX cable has an aluminium screen , which according to the manufacturer "provides all the safety benefits in the event of nail penetration", "screen provides instant response if penetrated by a conductive metal object and coupled with a type B circuit breaker. https://uk.prysmian.com/markets/electrification/industrial-and-construction/building-wires/lsx .

They and others seem to say that it's acceptable for burying less than 50mm and not protecting with a RCD

Cleavland have CSX that goes up to 10mm https://www.clevelandcable.com/en/BS8436-protected-screened-fixed-wiring-cable-1mm-10mm 

I would think the thinner cable is easier to work with a terminate inside a dwelling, I haven't seen many people talking about using it. I am wondering why?

    Not just "they" - but BS 7671 too - it's the BS 8436 type mentioned in 522.6.204. I rather like the stuff and my home is almost entirely wired using it.

    It is a lot more expensive than T&E though - and hard to obtain and when most domestic final circuits at least need 30mA additional protection for other reasons, it's hard to justify economically. Originally it was only readily available to BS up to 4mm2 (although larger sized were available to Irish standards) which limited its use as SWA replacement - it's also no clear that its sheath is suitable for underground or exposed outdoor use.
