Description
Application
This range of high temperature flexible cables is particularly adapted for all uses in industry or in specific equipment material for energy production as well as in leading sectors.
H07BN4-F cables are made with synthetic rubbers having an excellent temperature resistance and can be used for intensive applications. In this case H07BN4-F can be more adequate than standard H07RN-F cables for the same core section (wages of weight, dimension, and connection accessories). The use up to 1000 V in alternative current is authorized for protected static installation and for connecting of motors in lifting appliances.
Installation
This cable can be installed in open air or be buried but with extra mechanical protection (tube, gutter).
Conductors laid up
Assembled conductors.
USE <'HAR>H07 BN4-F N X (or G ) S
- N = number of cores
- G = with Green-Yellow
- x = without Green-Yellow
- S = section in mm²
Nota
Max continuous operating conductor temperature in normal use :
+90°C ( in every case of mobile installation)
+250°C ( in short circuit )
Permissible current rating is measured for an ambient temperature of 30°C and a maximum operating and conductor temperature of 90°C . For other temperature please refer to correction factors .
