CABLES AND WIRES - Novkabel

X00/AInsulated overhead lineStandard: SRPS N.C5.250Nominal voltage U 0 /U: 0,6/1 kVTest voltage:3 kVCONSTRUCTIONConductor: strand made from aluminium wires.Insulation: XLPE compound.Core: wires are bundle stranded.Wire marking: the cores of the phase conductors are markedwith numbers: 1,2,3. Neutral supporting core has got atriangular bulge along the whole length.APPLICATIONCable is used in distributive low-voltage air networks in urbanareas. Cable is intended for supply of facilities and villages oftemporary and permanent character. It can use for air householdconnections. It can be placed on concrete, steel or wooden poles,the console attached to the facade of the building, next to thefacade, onto wooden or steel construction.CONSTRUCTION DATAnxqAl number Diameter Mass[kg/km] [mm] [kg/km]2x16 93 15.7 1362x25 145 18.4 2084x16 186 18.9 2734x25 290 22.2 415189n – number of the wires, q – nominal cross section of the conductorPermissible temperature of the conductor:- operating temperature (constant load), max +90°C,- in short circuit (max 5 s), max +250°C.Permissible environment temperature:- at laying and handling, min -20°C.Smallest bending radius at bundle laying:- for cable - 14D (D - diameter cable),- for core - 6d (d - diameter core).Smallest bending radius after laying:- for cable - 6D (D - diameter cable),- for core - 4d (d - diameter core).
