、电缆终端头及中间接头等处都应留有备用长度一般6kV及以上电缆预留3～5m；3kV及以下电缆预留1.5～2m
6、通过铁路地区应采用防护措施预防地中杂散电流对电缆铅包的影响，应不选铝包电缆或将铅包电缆装在陶瓷或浸过沥青的石棉管中，以提高铅包对地绝缘，满足电缆与钢轨间zui小净距标准规范要求
7、敷设温度电缆存放地点在敷设前24h内的平均温度不能低于：塑料绝缘电力电缆0℃；橡皮绝缘电力电缆橡皮或聚氯乙烯护套-15℃，铅护套钢带铠装-7℃；控制电缆耐寒护套-20℃，橡皮绝缘聚氯乙烯护套-1。ECG6245DUAL,LPC47M192-NCALC201,HC-H6289,HCH-1H-12355HZ,LPC47M252-SG,APM3009,CR040216W360JT,CR0402-16W300J,25V16,25V1500-HEIP,CAP4761,M39003-01-2365,32-33027-83,323-30312101,372-0018-020,2.35127E+11,NJ88C24UA,W16305G,2351-26708-501,W1628SC系列芯片;单片机半导体;监控类系列芯片;偏冷门元器件;电源保护管理IC;军工级IC元器件;家用电器元器件;存储器芯片;内存闪存芯片SAWFD1G90BH0F0AR15,BCM20745A0KFBG,BCM20771A0KWFBG,BCM20702A1KWFBG MT6250M、MT6250A、MT6250D、MT6252C、MT6252A、MT6252D UC1524AJ/883/UC1524AJ/80503/SNJ54S283J/SN54S283J/SN54AS30J/CD54HC393F3A/CD54HCT163F3A/HM1-6514/HM1-6518/04N25/4N26/4N35/HY57V281620FTP-H/HY62256BLP-10/SP2525A-2EN/TRSP8034CB-2/TRSP3239EEA/TRSP385EET-L/LMV824MTX/EPM7160EQI100/15EPM7128EQI100/15EPM7096QC100/15EPM/LEGERITY/TOSHIBA/lATTICE/HOLTEK,HT1621B/HT1621B/48SSOP/HT1381/MAX6328UR23+TBCX70KT116 MPS系列：MP1410ES
