NHXCHX - Novkabel

1 NHXCHX Standard: DIN VDEO266 Nominal voltage Uo/U: kV Test voltage: 4 kV CONSTRUCTION Conductor: copper conductor (DIN VDE 0295 class 1 for single-wire cable and class 2 for multi-wire cable) Insulation: halogen free cross-linked mixture based on polyolefin (HXI1 DIN VDE 0266) Filler: halogen free mixture Concentric conductor: copper wire braid with counter coil made from copper tape Sheath: halogen free braided mixture, hardly flammable mixture based on polyolefin (HXM1, in compliance with DIN VDE 0266).

2 Color: for power cables black, for cables which are used for self-security current circles - blue. APPLICATION This type of cable is in accordance with the requirements of paragraph JUS (for objects class BD2, BD3 and BD4) and JUS , so it does not spread fire, not burning flame. These cables are designed for installation in buildings with increased requirements for safety of people and property, in buildings where rescue of people is difficult (high buildings all types in which resides a number of people), public, business and other objects for which it is important not to come to a quick spread of fire and endangering people with smoke.

3 Basic cable characteristics in case of fire: - do not spread flame (testing according to DIN VDE 0472 standards, part 804C), - combustion elements do not contain halogen elements (testing according to DIN VDE 0472 standards, part 813), - low density of smoke in the process of fire, (testing according to DIN VDE 0472 standards, part 816). They can be placed in the air on horizontal racks or in concrete in cable channels. It is allowed to lay cables in open space. Laying directly in the ground or water is not allowed.

4 TECHNICAL DATA Permissible temperature of the conductor: - in use (constant load) , max. + 90oC - in short circuit (max 5 s), max. + 250oC Working temperature: at laying, from + 5 up to 50oC Bending radius: - for one-wire cable, min. 15D; - for multi-wire and cables with more than one wire, min. 12D (D - cable diameter) Data for some cable construction n x q/qc mm2 Cu kg/km D mm Q kg/km n x q/qc mm2 Cu kg/km D mm Q kg/km 4x10/10 504 24 950 7x1,5/2,5 133 20 450 4x16/16 796 27 1300 10x1,5/2,5 176 23 650 4x25/16 1142 31 1900 12x1,5/2,5 205 24 700 4x35/16 1526 34 2300 24x1,5/6 413 31 1200 4x50/25 2203 39 3100 7x2,5/2,5 200 21 550 4x70/35 3082 43 4200 10X2,5/4 286 25 800 4x95/50 4208 47 5400 12x2,5/4 334 26 850 4x120/70 5388 52 6700 24x2,5/10 696 34 1600 n - number of wires.
