NH-90 450/750 V 35 mm2

Application:

Special application in places with poor ventilation, where, in case of fire, the emission of corrosive, toxic gases and smoke threatens life and destroys electrical and electronic equipment, for example in residential buildings, offices, industrial plants, movie, theaters, discotheques, hospitals, airports, underground stations, etc. In case of fire, possible victims have higher chances of surviving because they don't breath in toxic gases and have good visibility to escape the area. They are usually installed in conduits and in indoor areas in tray. Not recommended for outdoor installations. Not recommended for outdoor installations.

Construction:

Conductor: Compact soft copper, class 2.

Insulation: Halogen free thermoplastic compound HFFR.

Main characteristics:

Fire retardant, zero emission dense smoke and halogen free.

Cross section:

From 10 mm² up to 95 mm².

Marking:

NEXANS INDECO S.A. NH-90 450/750 V - Section - Year - (- sequential length m. || sequential length m. + ).

Packing:

Non returnable wooden reels.
