0.6/1kv Low Voltage Underground Copper/Aluminum Conductor XLPE Insulated PVC Sheathed Steel Wire Armoured Power Cable

 SpecificationProduct DescriptionLow Voltage Cable1. ApplicationThe cable is used in electric transmission and distribution system operating at AC rated voltage up to and including 1.8/3 KV2. Operating Characteristic1) The rated voltage U0/U of cable is 0.6/1KV.2) The long time allowable working temperature of conductor is 70 °C FOR cable with PVC insulation, 90 °C for cable with XLPE insulation.3) The cable laying temperature is not less than 0°C, and the allowable bending radius of a cable is not less 20 times than cable overall diameter for single core unarmored cable, 15 times of that for single core armored, 12 times of that for 3 cores armored cable.1. ScopeThe cables are manufactured and tested in accordance with IEC60502 Power Cables with Extruded Insulation and their accessories for rated voltages from 1kV(Um1.2 kV) up to 30kV(Um 36kV). Whereas, Greatwall Cable can supply XLPE insulation cables according to other recognized national and international standards or customized specification.2. Construction and Material1) ConductorConductors are normally class 2 of compacted cicular or circular standard conductors of copper or aluminium. 2) Conductor ScreenAll cable of rated voltage above 1.8/3kV are supplied with conductor screening which is non-mentallic and consists of either semi-conducting tape or a layer of extruded semi-conducting compound,or a combination of the two.3) InsulationInsulation is a layer of extruded cross-linked polyethylene(XLPE).4) Insulation Screen For cable at rated voltage above 1.8/3kV ,insulation screening consists of a non-metallic semi-conducting part in combination with a metallic layer and consists of either semi-conducting tape or a layer of extruded semi-conducting compound.. The extruded insulation screen is normally free strippable(easy removable) type but can be provided with bonded one upon request.  The metallic part is normally applied on the individual cores for rated voltage above 1.8/3kV and on the core assembly for rated voltage 1.8/3kV and consists of plain annealed copper tape. or copper tape screen a layer of copper wire,a lead alloy or corrugated aluminum sheath can be provided upon request.  5) Inner Covering or Separation Sheath(for armored cables)A layer of PVC inner coveing is applied under the armor ,if there is no screen.When the metallic screening and the armor are of different metals, an extruded separation sheath of PVC is provided in order to separate the different metals.6) Metallic ArmorThe armor, if required, consists of single layer of round wires or double tapes of galvanized steel or aluminum or other non-magnetic metals. Single core cables are normally armored with aluminum(other non-magnetic metals),  because non-magnetic armor is essential for single core cable for use on A.C circuit .7) Outer SheathAll cable are normally provided with an extruded PVC out sheath, black colored(class ST2). Other materials can be available upon request,as PE , polyethylene,high flame or fire retardant PVC and etc.8) Core Identification The multiple conductors are identified as according IEC60502 .  Cable Marking(Customized) The following information are indicated on the surface of the outer sheath. However, the marking can also be customized. ----voltage rating, area for cable----manufacturer's name----year of manufacturer----lengther for cable----etc3.Typical DrawingPARAMETERS Cores and Nominal Cross Section Area:Rated voltage 0.6/1kV  Single core  Basic parameter of Power CableNominal cross sectionmm2Thickness of insulationmmCU/XLPE/PVC;AL/XLPE/PVCApproximate weight of cable kg/km    Approximate weight of cable kg/kmThickness of sheathmmApprox. overall diameter of cable mmCU/XLPE/PVCAL/XLPE/PVCInner covering mmThickness of steel tape mmThickness of sheath mmApprox. overall diameter of cable mmCU/XLPE/SWA/PVCAL/XLPE/SWA/PVC1.50.70.75.64535      2.50.70.765641      40.70.76.57449      60.70.779559      100.70.78.213979      160.70.79.1197102      250.90.910.62931430.90.21.814451301350.90.911.63861780.90.21.8155583495011135072250.90.21.816.4698416701.11.114.97083000.90.21.818.3926519951.11.116.89593940.90.21.82011946281201.21.218.511934790.90.21.821.714507371501.41.420.614705900.90.21.823.617458651851.61.622.818317300.90.21.825.6212210212401.71.725.723809330.90.21.928.5270612593001.81.828.3296011440.90.21.930.9330414884002231.3375514331.20.52.135.944942173Rated voltage 0.6/1kV  Two cores  Basic parameter of Power CableNominal cross sectionmm2Thickness of insulationmmCU/XLPE/PVC,AL/XLPE/PVCApproximate weight of cable kg/km    Approximate weight of cable kg/kmThickness of sheathmmApprox. overall diameter of cable mmCU/XLPE/PVCAL/XLPE/PVCInner covering mmThickness of steel tape mmThickness of sheath mmApprox. overall diameter of cable mmCU/XLPE/SWA/PVCAL/XLPE/SWA/PVC1.50.71.810.2114960.90.21.812.82322142.50.71.8111411110.90.21.813.626923840.71.8121811320.90.21.814.632027160.71.8132281560.90.21.815.6379306100.71.815.43312110.90.21.818509389160.71.817.24582680.
