ABC cable standard NFC33-209

NFC33-209 standard specifies the rated voltage 0.6/1kV.
Low voltage overhead power systems use the XLPE insulated wire bundles.
Structural characteristics and performance requirements must be met.
Wire bundle can contain public lighting lines and testing lines.
This standard specifies performance characteristics of this insulated wire bundles and the test items that must be met.
Insulation shall be black extruded XLPE which is easily stripped.
For slings neutral, Conductor should be around the package tape isolation layer.For other wire (line, public lighting line and test line),it will be both ok whether to adopt an optional isolation barrier . However, if using insolation layer, It should be overall colored, and the wiring harness of the same nominal cross section of the conductors are all the same.
This product is suitable for AC rated voltage of 450/750V or less,like subway, high-rise buildings, shopping malls, theaters, power plants, chemical plants, city squares and other public utilities which have higt requirements of flame-retardant properties of the cable. The cables characteristics of LSZH and low smoke low halogen have many benefits,like when the fire broke out, the fire spread slowly, low smoke density, high visibility, small emission of harmful gases, to facilitate evacuation. Less corrosive combustion gases, also to avoid damage to the equipment, low halogen, halogen-free, which makes the cable materials greatly enhance the anti-aging and resistance to ultraviolet light and other radiation performance, thereby extending the life of the cable.
