PC NH-90 450/750 V 4 mm2 AM-VD

Description

Description

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. 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

Construction:

1. Conductor: Soft copper, class 2.

2. Insulation: Halogen free thermoplastic sliding material HFFR.

Main characteristics:

Fire retardant, low emission dense smoke and halogen free.

  • Fire retardant, zero dense smoke emission and halogen free.
  • Easy and fast opening due to its innovative OPEN FAST die-cut packaging.
  • Easy installation due to its sliding insulation, it does not need any type of lubricant for installation in pipes.
  • Easy to measure due to its double sequential marking called METRIUM which allows to quickly read the installed lengths.
  • Use of VIGICHECK technology product originality identification hologram.

Cross section:

From 1,5 mm2 up to 6 mm2.

Marking:

INDECO BY NEXANS PC NH-90 450/750 V - Section - H07Z1-R TYPE 2 - Year - MADE IN PERU (- sequential length m. || sequential length m. + ).

Packing:

In standard 100 meter rolls with VIGICHECK hologram.

Colour:

Yellow/green, green.
