Application
The cables are similar in design and application to CW 1600, but with fire barrier tape. They are used for the internal wiring of building when the circuit integrity during fire is paramount. The cable is intended to take the place of LSZH sheathed cables and will withstand similar environments with a similar working life. The cables are intended for use in fire fighting plants with mica tapes, with and without aluminium foil and LSZH outer sheath.
Standards

Construction
Conductors
Solid annealed bare or tinned copper sized 0.8mm as per class 1 of VDE 0295/IEC 60228
Fire Barrier
Mica tape
Insulation
LSZH compound HI1 as per VDE 0207-23
Twisted Pairs
Insulated conductors are twisted into pairs with varying lay length to minimize crosstalk
Cabling Element
Twisted Pairs
Core Assembly
The twisted pairs are stranded to the core in layers
Core Wrapping
One or more non hygroscopic polyester tapes are helically or longitudinally laid with an overlap prior to sheathing
Screen
A laminated Aluminium/Polyester tape in contact with solid copper 0.6mm or 0.8mm drain wire
Inner bedding (for armoured cables)
PE or LSZH compound HM2 as per VDE 0207-24
Armour (for armoured cables)
Either corrugated steel tape armour or galvanized steel wire is applied over an inner polyethylene sheath. For steel tape armour, the 0.15mm thick steel tape is coated with a copolymer and applied with an overlap. For steel wire armour, single layer of galvanized steel wire armour is applied.
Sheath
LSZH compound HM2 as per VDE 0207-24
Ripcord
Nylon ripcord may be placed parallel to the cores to facilitate sheath removal
Drain Wire
A solid tinned earth/continuity wire shall be laid longitudinally for screened cables

Fire Hazard Performance
| 1) Minimum Smoke Emission |
IEC 61034, EN 50268 (New: EN 61034), VDE 0482-268 (New: VDE 0482-1034)
These standards specify a method to measure the generation of smoke from cables during fire. The result is expressed as percentage of light transmitted. Usually, the smoke density shall not be less than 60%. |
| 2) Halogen Free |
IEC 60754-1, EN 50267-2-1
These standards specify a method for determination of the amount of halogen acid gas, evolved during combustion of compound. The hydrochloric acid yield should be less than 0.5%. |
| 3) Non corrosive gases |
IEC 60754-2, EN 50267-2-2, VDE 0482-267
These standards specify a method for determination of acidity of gas evolved during combustion of cables by measuring PH and conductivity. The specimen is deemed to pass this test if the pH value is less than 4.3 when related to 1 litre of water and conductivity is less than 10 μs/min |
| 4) Reduced Fire Propagation |
IEC 60332-3C, EN 50266-2-4, VDE 0482-266-2-4
These standards specify a method for flame propagation test for bunched cables. |
| 5) Flame Retardancy |
IEC 60332-1, VDE 0482-265-2-1
These standards specify a method for flame propagation test for single core cables |
| 6) Insulation Integrity FE 180 |
DIN VDE 0472-814, IEC 60331, EN 50200, VDE 0482-1
These standards specify the performance requirements for cables required to maintain insulation integrity under fire conditions |
| 7) Circuit Integrity E30 |
DIN 4102-12
These standards specify the performance requirements for cables required to maintain circuit integrity under fire conditions |
