SXXI(i) screened fire resistance instrumentation cable construction

Classification	Code	Construction detail
Conductor		Stranded plain annealed copper wires as per IEC 60228, Class 2
Fire resisting layer	S	Mica/glass tape
Insulation	S	XLPE as per IEC 60092-351
Twisting		Two/Three Insulated cores shall be twisted together to form a pair/triad
Individual screen	(i)	-Screened by AL/PS tape with tinned copper drain wire -Each pair/triad is wrapped with polyester tape to prevent electrical contact with adjacent pairs/triads
Cabling		- Screened pairs/triads shall be cabled - Flame retardant & non-hygroscopic fillers may be used - Suitable tape(s) may be applied on the cabled core - A Filler may be applied to obtain a circular Cable
Collective screen	(c)	- Screened by AL/PS tape with tinned copper drain wire - A suitable tape may be applied on the collective screen - In case of 250V BI(i)cable, collective screen is omitted - SHF1 as per IEC 60092-359
Sheath	I	- Sheath color : Black - Colored insulation plus Arabic number printing on the insulation
Core identification		Pair : White, Black Triad : White, Red, Black

Note.
The other color of sheath and insulation may be applicable when purchaser required.
Stranded tinned annealed copper wire as per IEC 60228, Class 2 may be applicable when purchaser required.
