DESCRIPTION

Application:

Special application in places with poor ventilation, where, in case of fire, the emisión 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. 100% purity copper, double layer, double protection. Not recommended for outdoor installations

Construction:

1. Conductor: Soft copper, class 2.

2. Insulation: Halogen free thermoplastic material HFFR, double layer.

Main characteristics:

Fire retardant, low emission dense smoke and halogen free.

Cross section:

From 1,5 mm2 up to 10 mm2.

Marking:

INDECO S.A. FREETOX NH-80 450/750 V - Section - Year - Sequential length.

Packing:

From 1,5 mm2  up to 6 mm2  in 100-meter standard coils.

10 mm2 in reels.

Colour:

At the customer's request.
