3、注意包装。线缆产品的包装与其它产品一样,凡是生产产品符合国标要求的大中型正规企业,生产的电缆线很注意产品包装。选择采购时注意包装要精美,印刷要清晰,型号规格、厂名、厂址等齐全。
控制电缆投入运转后,相同电缆的不同线芯之间,紧挨平行敷设的电缆之间都存在电气的问题,引起电气的主要原因有:(1)由于外施电压在线芯间电容耦合的作用下产生的静电;(2)由于通电电流产生的电磁感应。0CrNi2Si2MoV,4340,SNCM439,40CrNiMoA,20CrNi2Mo ,20CrMnMo ,40CrMnMo ,35CrMo ,42CrMo,4140,4130,SAE8620,45CrNiMoVA,16MnCr5,15CrMn,38CrMoAlA,20MnCr5,20CrMn,18Cr2Ni4WA ,12CrNi3,20Cr2Ni4A ,35CrMnSiA,30CrMnSiA,18CrNi3Mo,25Cr2MoV,22CrMoH,20CrMnMo,20CrMnTi,30CrMnTi,25CrNiMoV,20CrNiMo,G20CrNi2Mo,30Cr2Ni2Mo,17Cr2Ni2Mo,17CrNiMo6,18CrNiMo7,34CrNiMo6,30CrNiMo8,40CrNi。45CrNi,20Ni4Mo,20CrMnSiNi2A,30CrMnSiNi2A,38CrSi,34CrNi1Mo,12CrNi3A,20CrNi 30CrNi3A,34CrNi3A,37CrNi3A,34CrNi3MoA,37CrNi3MoA,12Cr2Ni4A,20Cr2Ni4A,18Cr2Ni4W,25Cr2Ni4W,25Cr2MoV,25Cr2Mo1V,12CrMo,12Cr1MoV,35CrMoV,45Cr2MoV,18CrNi3MoA,20CrNi3MoA,25CrNi3MoA,,22SiMnCrNi2MoVA,5CrW2Si河北唐山施工剩余回收电缆各种报废电缆电线回收常年上门
