Description:

1.The permissible long-time operationg temperature for aerial conductor is 70C, the circumstance that long distancce rare climate and ice coverage rare occurring in heavy ice area, the most biggest stress of Aluminium/Copper Stranded Conductor  at the lowest arc downing point should not exceed 60% of the destructive power at a short time. 2.New type of Aluminium/Copper Stranded Conductor: JL, JL/G1A, JL/G1B, JL/G2A, JL/G2B, JL/G3A Norminal Area mm2 Stranding No./Dia mm Calculated Area mm2 Outside Diameter mm DC Resistance Ω/km Calcuated Breaking Load N Calculated weight kg/km Delivery legth m 16 25 35 50 70 95 120 150 185 210 240 300 400 500 630 800 7/1.70 7/2.15 7/2.50 7/3.00 7/3.60 7/4.16 19/2.85 19/3.15 19/3.50 19/3.75 19/4.00 37/3.20 37/3.70 37/4.16 61/3.63 61/4.10 15.89 25.41 34.36 49.48 71.25 95.14 121.21 148.07 182.80 209.85 238.76 297.57 397.83 502.90 631.30 805.36 5.10 6.45 7.50 9.00 10.80 12.48 14.25 15.75 17.50 18.75 20.00 22.40 25.90 29.12 32.67 36.90 1.802 1.127 0.8332 0.5786 0.4018 0.3009 0.2373 0.1943 0.1574 0.1371 0.1205 0.09689 0.07247 0.05733 0.04577 0.03588 2740 4355 5760 7930 10950 14450 19420 23310 28440 32260 36260 45850 61150 76370 91940 115900 43.5 69.6 94.1 135.5 195.1 260.5 333.5 407.4 50.0 577.4 656.9 820.4 1097 1387 1744 2225 4000 3000 2000 1500 1250 1000 1500 1250 1000 1000 1000 1000 1000 1000 800 800
