Operating Temperature vs Installation Temperature
For many EN 50200, BS 6387, CPR, PH30, and BS 7629 fire cable families, ZION lists operation from -30℃ up to +180℃ and installation from -5℃ up to +50℃. UL fire alarm cable families list operation from -20℃ up to +75℃ and installation from 0℃ up to +65℃.
Minimum Bending Radius
The catalog lists minimum bending radius as a multiple of cable diameter. Many EN/BS/CPR fire resistant cable families list 8× cable diameter. JE-H(St)H FE180-E30/E90 and UL fire alarm cable families list 7.5× cable diameter.
| Cable Family Context | Minimum Bending Radius | Planning Note |
|---|---|---|
| EN 50200, BS 6387, CPR, PH30, BS 7629 families | 8× cable diameter | Check outer nominal diameter before routing. |
| JE-H(St)H FE180-E30/E90 | 7.5× cable diameter | Useful for communication cable route planning. |
| UL plenum and riser fire alarm families | 7.5× cable diameter | Use with AWG, conductor count, and jacket diameter data. |
Why Outer Diameter Tables Matter
Product tables list nominal outer diameter with tolerance, such as ±0.2 mm or ±0.3 mm depending on the family. Larger core counts and larger conductor sizes increase the outer diameter, which changes bending radius, tray fill, conduit fit, and handling needs.
Packing and Site Handling
Popular packing listed in the catalog includes 100 m, 300 m, and 500 m wooden spool options for several EN/BS families, and 500 ft or 1000 ft reel or pull box options for UL fire alarm cable families. Confirm packing together with installation sequence and site access.
FAQ
Can a cable be installed outside the listed installation temperature?
Do not assume so. Installation temperature is a separate datasheet limit and should be confirmed for the project environment.
How is bending radius calculated?
Use the datasheet multiple, such as 8× or 7.5× cable diameter, and apply it to the selected cable's outer diameter.
Why does packing length matter?
Packing length affects handling, site storage, pulling sequence, and whether a route can be installed without unnecessary joints.
