18kv Yjv22 Power Cable Single Core 630mm2 XLPE Data Power Cable

18kV YJV22 power cable single core 630mm2 XLPE data power cableIntroduction:        For XLPE insulated power cable, either chemical method or physical method is employed to transform the molecular structure of PE from chain into three-dimensional network, i.e. thermo-plastic PE is transformed into thermosetting XLPE. After cr·oss-linking, the thermal and mechanical properties of PE have been greatly improved while its excellent electrical property are still retained.       The maximum permissible operating of the conductor of a XLPE insulated power cable is 90°C.which is higher than that of paper, PVC or PE insulated power cable. The cable has the advantage of simplicity in construction, lightness in weight, convenience in application besides its excellent electrical, thermal, mechanical and anti-chemical corrosion properties. It can also be laid with no limitation of level difference along the route.       The mechanical and electrical properties of these cables are accordant with GB/T12706-2002 Power cables extruded insulation and their accessories of elated voltages 1kV(Um=1.2kV)up to 35kV(Um=40.5kV) and IEC60502-1997 Extruded insulation power cables and appendices for rated voltages 1kV up to 30kV.Description:1) Rated Voltage:  18/30KV 2) Max. working temperature: 90 °c3) Max. temperature during short circuit (≤5S): 250 °c4) Conductor: class 1, 2 copper or aluminum5) Sectional area: 1x50 - 630mm2,3x50 - 400mm26) Insulation: XLPE7) No. of cores: 1, 38) Armor: steel wire or steel tape for 3 core cables and non-magnetic material for single core9) Oversheath: PVC/XLPE10) Min. beding radius: 15 times cable radius for single-core cables and 12 times for multi-core ones11) Max. conductor DC resistance at 20°c:Stardand:IEC 60502, 60228, 60332, 60331DIN VDE 0276-620HD 620 S1: 1996DIN EN 60228 class 2 (construction)Application:  TypeConductorApplicationYJV/YJLVCU/ALFor laying in door,tunnel,channel and underground.Unable to bear external mechanical force,but bear the traction force during laid.YJV22/YJLV22CU/ALFor laying in tunels in door,tunnel,channel and underground.Able to bear external mechanical force,but unable to bear large pulling force.YJV32/YJLV32CU/ALFor laying in shaft with large difference of level.Able to bear external mechanical force,and moderable pulling force.Technical Parameters:Nominal cross sectional area of conductor(mm²)lnsulation thickness (mm)Sheath thickness (mm)Approx. overall diameter of cable(mm)Approx.weight Of cable (kg/km)D.C resistance of conductor(Ω/km)Testing voltage     A.CCurrent ratingIn air(A)Direct in soil(A)CuAICulAl(kV/5min)CuAlCuAl1x508.02.03315601250≤0.387≤0.641632101602151601x708.02.13518401400≤0.268≤0.443632602002652001×958.02.13621401550≤0.193≤0.320633202453152401x1208.02.23824501700≤0.153≤0.253633702803602701x1508.02.23927901860≤0.124≤0.206634203204053051x1858.02.34132002050≤0.0991≤0.164634803654553451x2408.02.34338002310≤0.0754≤0.125635654355304001x3008.02.44544602600≤0.0601≤0.100636505005954551x4008.02.54955303060≤0.0470≤0.0778637555856805201x5008.02.65361603560≤0.0366≤0.0605638656807655951×6308.02.75680204120≤0.0283≤0.04696310007908606803x508.02.85552904350≤0.387≤0.641631751301801403x708.02.95962404930≤0.268≤0.443632201652201703x958 03.06273605580≤0.193 ≤0.320632552002652103x1208.03.16683506100≤0.153 ≤0.253632902253002353x1508.03.26995206410≤0.124 ≤0.206633302553402603x1858 03.472108307370≤0.0991 ≤0.164634352953803003x2408.03.577128108300≤0.0754 ≤0.125634953454353453x30083.782149209300≤0.0601 ≤0.100635653904853903x40083.9901811010620≤0.0470 ≤0.077863640450520440Product Show:/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
