CABLES AND WIRES - Novkabel

XHP 48/O-A; XHE 49/O-ACable for overhead linesStandard: SRPS N.C5.230Nominal voltage U 0 /U: 3.6/6kV; 6/10kV; 12/20kV; 20/35kVTest voltage: 9kV; 15kV; 30kV; 50kVCONSTRUCTIONPhase conductorConductor: compacted multi-wire aluminium conductor class 2according to SRPS N.C0.015.Inner semi-conductive layer: thermo stabile material.Insulation: XLPE compound.Outer semi-conductive layer: semi-conductive layer made fromthermo stable material with sheath made from wrapped semi-conductivetape in case of XHP 48/O-A type of cable or made from semi-conductiveswelling tape in case of XHE 49/O-A type of cable.Electrical protection: wrapped copper wire with contra-helical coppertape.Separator: polyester tape in case of XHP 48/O-A type of cable, andwaterproof insulating swelling tape in case of XHE 49/O-A type of cable.Sheath: PVC compound for XHP 48/O-A type of cable; PE compound forXHE 49/O-A type of cable.Sheath colour: black.Supporting elementRope: Zinc-plated steel rope, 50 mm 2 nominal cross-section, accordingto SRPS C.H1.061. Minimal tensile strength: 72,11kN, elasticity module:17500daN/mm 2 . Rope diameter: 9mm.Rope is covered with black polyethylene layer. Diameter of the covering:12 mm.APPLICATIONCable is used instead of overhead lines in rural networks, in areaswith intensive object and traffic constructions, when the problemsof safety lengths arise from limited areas. The cable is laid on thepillars of the air network. It can be laid partially in earth wherethat is necessary.CONSTRUCTION DATA1923,6/6 kV 6/10 kV 12/20 kV 20/35 kVn x q/q 1+ q o Al Cu Diameter Mass Diameter Mass Diameter Mass Diameter Mass[mm 2 ] [kg/km] [kg/km] [mm] [kg/km] [mm] [kg/km] [mm] [kg/km] [mm] [kg/km]3x1x25/10+50 216 360 41 1632 45 1846 - - - -3x1x 35/10+50 306 360 45 1800 50 2027 58 2660 - -3x1x 50/16+50 435 546 50 2207 54 2449 62 2961 78 40163x1x 70/16+50 609 546 52 2494 56 2750 65 3263 82 44693x1x 95/16+50 828 546 56 2841 60 3252 69 3715 86 49213x1x 120/16+50 1044 546 60 3127 65 3413 73 4016 88 53733x1x 150/25+50 1305 856 62 3715 67 4016 78 4770 93 5976q – nominal cross section of the conductor, q 1 – nominal cross section of the electrical protection, q o – nominal crosssection of the supporting elementPermissible temperature of the conductor:- operating temperature (constant load), max +90°C,- in short circuit (max 5 s), max +250°C,- short-term in emergency up to +130°C.Permissible environment temperature:- XHP 48/O-A, at laying, min -5°C; at laying, for bundles, min -40°C;- XHE 49/O-A, at laying, min -20°C; at laying, for bundles, min -50°C.Smallest bending radius: 15 D (D – diameter cable).
