CABLES AND WIRES - Novkabel

X00/O-AInsulated overhead lineStandard: SRPS N.C5.250Nominal voltage U 0 /U: 0,6/1 kVTest voltage: 3 kV for phase conductor; 2 kV for public illumination conductorCONSTRUCTIONConductor:- phase conductor and public illumination conductor: rope consistsof aluminium wires,- supporting neutral conductor: rope of aluminium alloy AlMgSi.Insulation: XLPE for each element of the bundle.Bundle: stranded cores around neutral conductor.Core marking:- the cores of the phase conductors are marked with numbers:1,2,3.- neutral supporting core has got a triangular bulge along thewhole length.- public illumination cores are marked by the identifications R1 andR2.APPLICATIONCable is used for distributive low-voltage air networks in urbanareas. Cable is intended for supply of remote facilities and villagesof temporary and permanent character. It can use for airhousehold connections. Reduces the risk of short circuit due tocontact with the conductor, vault, it is easy to set and requires nocutting of trees along the route. It can be placed on concrete,steel or wooden poles; the console attached to the facade of thebuilding, next to the facade, the wooden or steel construction.CONSTRUCTION DATA1903 x q + q o + n x q 1Mass3 x q + q o + n x q 1Mass[mm 2 ][kg/km][mm 2 ][kg/km]3X25+ 70 597 3X50+ 70+1x16 9133X25+ 70+1x16 665 3X50+ 70+2x16 9813X25+ 70+2x16 733 3X70+ 70 10643X35+ 70 710 3X70+ 70+1x16 11323X35+ 70+1x16 779 3X70+ 70+2x16 12003X35+ 70+2x16 847 3X70+ 70+1x16 11683X50+ 70 845 3X70+ 70+2x16 1272q – nominal cross section phase conductor, q o – nominal cross section neutral conductor, n – number wires for publicillumination, q 1 – nominal cross section conductor for public illuminationPermissible 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 bundle with q ≤ 50 mm 2 - 6 D (D – diameter bundle),- for bundle with q = 70 mm 2 - 9 D (D - diameter bundle),- for wire - 4 d(d 1) (d – diameter wire phase conductor, d 1 - diameter wire public illumination).Smallest bending radius during installation:- for bundle with q ≤ 50 mm 2 - 14 D (D – diameter bundle),- for bundle with q = 70 mm 2 - 9 D (D - diameter bundle),- for wire - 6 d(d 1) (d – diameter wire phase conductor, d 1 - diameter wire public illumination).
