1KV, 10KV overhead insulated cable for AC rated voltage 1KV-10KV power transmission and distribution system.
Executive standard 1KV overhead insulated cable implementation standards for the GB / T12527-2008 and GB/T1179-2008;10KV overhead insulated cable implementation standards for the GB / T14049-2008 and GB / T1179-2008. Note: 1.1KV overhead insulated cable can produce 1 core 2 cores 4 cores 10-400mm², 10KV overhead insulated cable to single core,
2.the production range of 16-400mm ². 3.Steel core reinforced steel core cross-section selection, according to steel core aluminum wire tensile streng requirements to determine. Characteristics 1.The rated voltage U0 / U:0.6 / 1KV,10KV. 2.The long-time working temperature of cable conductor is ≤70ºCPVC, or ≤90ºCXLPE. When short circuit(longest time of duration isn"t over 5s), the highest working temperature of cable is ≤170ºCPVC or ≤ 250ºCXLPE 3.The laying temperature is ≥-20ºC, the cable should be warmed up when below this temperature 4.The minimum curved radius.
a.1KV: ≥4D; Steel core reinforced type ≥6D (D<25mm); ≥6D; Steel core reinforced type ≥10D (D≥25mm). b.10KV: single core ≥20D; Steel core reinforced type ≥25D; multi-core ≥15D; Steel core reinforced type ≥20D
