LSZH sheath, LTS3
Low smoke halogen free thermoplastic. Red or white as standard. The aluminium tape screen is bonded to the inside of the sheath, so stripping the sheath takes the screen with it.
Product range
A low smoke zero halogen, screened fire performance cable with silicone E12 insulated solid conductors and an aluminium tape bonded to the outer sheath. LPCB approved under certificate 1812d to BS 6387:2013 Category CWZ and EN 50200:2015 Class PH30.
Ordering codes
Two core with CPC, solid conductor, supplied on robust plastic reels. Other lengths, core counts and sheath colours are available to order.

The LPCB approval covers 1.0mm², 1.5mm² and 2.5mm² solid conductors in 2, 3 and 4 core constructions. Sizes outside the stock list above are supplied to order — ask us for a lead time.
Construction
Low smoke halogen free thermoplastic. Red or white as standard. The aluminium tape screen is bonded to the inside of the sheath, so stripping the sheath takes the screen with it.
A full aluminium tape screen with a tinned copper drain wire gives a high level of data protection on signalling and audio circuits.
Fire resistant low smoke zero halogen silicone insulation over bare solid copper, with mica tape in the lay-up rather than on the conductors.
