How to read a Layer-list designation (CU/XLPE/SWA/PVC style, IEC and BS practice) cable code

A Layer-list designation (CU/XLPE/SWA/PVC style, IEC and BS practice) designation (UK / International) is a row of letter groups, and each group stands for one part of the cable: conductor, insulation, screen, armour, sheath, or the standard it follows. The decoder knows 117 symbols for this system.

What does MGT mean in a Layer-list designation (CU/XLPE/SWA/PVC style, IEC and BS practice) cable code? MGT means Mica Glass Tape (fire barrier).

What does XLPE mean in a Layer-list designation (CU/XLPE/SWA/PVC style, IEC and BS practice) cable code? XLPE means Cross-Linked Polyethylene (XLPE).

What does OSCR mean in a Layer-list designation (CU/XLPE/SWA/PVC style, IEC and BS practice) cable code? OSCR means Overall Screen.

What does LSZH mean in a Layer-list designation (CU/XLPE/SWA/PVC style, IEC and BS practice) cable code? LSZH means Low Smoke Zero Halogen Compound.

What does SWA mean in a Layer-list designation (CU/XLPE/SWA/PVC style, IEC and BS practice) cable code? SWA means Steel Wire Armour (round galvanised steel wires).

What does PVC mean in a Layer-list designation (CU/XLPE/SWA/PVC style, IEC and BS practice) cable code? PVC means Polyvinyl Chloride (PVC).

Fire behaviour (EU CPR)

Halogen-free compound (LSZH). Under the CPR this shows in the additional classes: acidity a1 to a3 (EN 60754-2) and smoke s1 to s3 (EN 50399; s1a and s1b add the 3 m cube test EN 61034-2). The main class, Aca to Fca, depends on the whole construction.
Typically targeted, as declared by makers for this kind of construction in the examples this site checked (not the class of this cable):
- B2ca-s1,d0,a1 1-CXKH-R-J, Kablo Vrchlabí
- Cca-s1b,d1,a1 FG16(O)M16, Nexans (La Triveneta Cavi)
- B2ca-s1a,d1,a1 FG18(O)M16, Nexans (La Triveneta Cavi)
- Dca FXQJ, Nexans Norway
- Cca-s1,d1,a1 H07Z1-K, Nexans Spain
- B2ca AXQJ-RMF, Prysmian Sweden (12/20 kV)
- Cca-s1b,d1,a1 RZ1FZ1-K (AS), Top Cable
- Cca-s1a,d1,a1 RZ1-K (AS), Top Cable (B2ca-s1a,d1,a1 for some sizes)
