SR Insulated & LSZH Sheathed Fire Resistant Cables to DIN VDE 0815
JE-H(St)H…Bd FE180 E30 JE-H(St)H…Bd FE180 E30 BMK
Application
The cables are similar in design and application to CW 1600, but with Silicon Rubber Insulation. They are used
for the internal wiring of building when the circuit integrity during fire is paramount. The cables are intended for
use in fire fighting plants with special ceramized silicon insulation, with and without aluminium foil and LSZH
outer sheath
Standards

EN 50266
EN 50267
EN 50268
BS 6387
IEC 60331
DIN VDE 0472-814
Construction
Conductors
Solid annealed bare or tinned copper sized 0.6/0.8/0.9mm as per class 1 of VDE 0295/IEC 60228
Insulation
Silicon Rubber compound as per DIN VDE 0266
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 is placed in contact with solid copper 0.6mm or 0.8mm drain wire
Inner bedding (for armoured cables)
PE or LSZH compound.
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) Temperature Index | BS EN ISO 4589-3, BS 2782 Part 1 These standards specify a method for measuring the temperature Index of materials. The temperature index shall be equal or greater than 280ºC. |
| 7) Oxygen Index | BS EN ISO 4589-2, BS 2863 These standards specify a test for measuring the minimum oxygen concentration to support candle like combustion of plastics. The oxygen index shall not be less than 30%. |
