Description
Technical Data
Conductor : Thin strands of electrolytic copper are multi-drawn for uniformity of resistance, dimension and flexibility. The strands are twisted with high precision to impart circularity for the conductor.
Insulation : Polyolefin cross linked EI5 to BS EN 50363-5 Low Smoke Zero Halogen (LS0H).
Insulation Conformity : EN 60332-1-2, EN 60332-3 & EN 60754-1 & 2
Colours : Green, Black, Red, Yellow, Blue, Grey, White
Marking : The cables are marked ‘FIREX LS0H’
Packing : 90 mtrs. Coils packed in protective cartons.
Standard : BS EN 50525-3-41
Temperature range : -15°C to +90°C
Properties
The insulation does not burn readily. It does not melt and drip, smoke is negligible, transparent, non-toxic. In a fire situation the people trapped in fire do not suffocate. This facilitates fire fighting and rescue operations. This cable has extended service life against the conventionally used cables.
Ozone resistant according to EN 60811-2-1
