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

• EN 50200:2000-02
• EN 50266
• EN 50267
• EN 50268
• BS 6387
• IEC 60331

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
