RockwellAllen-Bradley1794-OE121794-OF4I1)外力损伤。由近几年的运行分析来看，尤其是在经济高速发展中的上海浦东，现在相当多的电缆故障都是由于机械损伤引起的。比如：电缆敷设安装时不规范施工，容易造成机械损伤；在直埋电缆上搞土建施工也极易将运行中的电缆损伤等。有时如果损伤不严重，要几个月甚至几年才会导致损伤部位彻底击穿形成故障，有时***严重的可能发生短路故障，直接影响用电单位的安全生产。2)绝缘受潮。这种情况也很常见，一般发生在直埋或排管里的电缆接头处。比如：电缆接头制作不合格和在潮湿的气候条件下做接头，会使接头进水或混入水蒸气，时间久r在电场作用下形成水树枝，逐渐损害电缆的绝缘强度而造成故障。3)化学腐蚀。电缆直接埋在有酸碱作用的地区，往往会造成电缆的铠装、铅皮或外护层被腐蚀，保护层因长期遭受化学腐蚀或电解腐蚀，致使保护层失效，绝缘降低，也会导致电缆故障。化：单位的电缆腐蚀情况就相当严重4)长期过负荷运行。超负荷运行，由于电流的热效应，负载电流通过电缆时必然导致导体发热，同时电荷的集肤效应以及钢铠的涡流损耗、绝缘介质损耗也会产乍附加热量，从而使电缆温度升高。长期超负荷运行时，过高的温度会加速绝缘的老化，以至绝缘被击穿。尤其在炎热的夏季，电缆的温升常常导致电缆绝缘薄弱处首先被击穿，因此在夏季，电缆的故障也就特别多。5)电缆接头故障。电缆接头是电缆线路中***薄弱的环节，由人员直接过失(施工不良)引发的电缆接头故障时常发生。施工人员在制作电缆接头过程中，如果有接头压接不紧、加热不充分等原网，都会导致电缆头绝缘降低，从而引发事故。6)环境和温度。电缆所处的外界环境和热源也会造成电缆温度过高、绝缘击穿，甚至***起火。7)电缆本体的正常老化或自然灾害等其他原因.Ort:KanadaNEWKollmorgenServostardriveCE10560,1YrWarranty,...Ort:KanadaKollmorgenServomotorMTC1504A1-E2C1NEW,WarrantyOrt:KanadaSTXIE20030IC,IGBTDRIVEROVERNIGHTSHIPOrt:KanadaPersonalitymodulePM030BF4075R-09105-0059-002for...Ort:KanadaNEWPRXIGBTKD324510OVERNIGHTSHIPPING***AILABLEOrt:KanadaFANUCBIF04A1TYPE:A03B-0808-C001I/OmoduleGOODOrt:KanadaNEWMITSUBISHIIGBTQM150DY-HOVERNIGHTSHIPPINGOrt:KanadaElectro-craftBSASERIESBSA-15SERVODRIVE9106-0081Ort:KanadaSIEMENS1FK6064-7AF71-1?TH0SERVOMOTORRESOLVERWARRNTYOrt:KanadaKollmorgenServostarCDServodriveCR06250,1YearWarr...Ort:KanadaNEWKOLLMORGENGoldLineServoMotorB-204-B-39-016FASTOrt:KanadaElectro-CraftPRO-300PRO300ServoControllerShipFastOrt:KanadaKollmorgenServostarSE20000FASTSHIP,1YRWarrantyOrt:KanadaKollmorgenServostarCDCB10561,1YrWarranty,1days...Ort:KanadaSIEMENS6SN1123-1AA00-0?KA1LTModuleINT400A1YrWrtyOrt:KanadaSIEMENS6SC116111-2AA00?-G600-D490/10-M?6REQSIMODRIVEOrt:KanadaNEWKOLLMORGENGoldLineServoMotorMTC304B1-R1C1-0?28Ort:Kanada2RollsFILMKX-FA134forPanasonicKX-F1200F1006F102...Ort:KanadaNEWKollmorgenServostardriveCE10260,1YrWarranty,...Ort:KanadaKollmorgenServostarSR20000FASTSHIP,1YRWarrantyOrt:KanadaSPINDLEORIENTMotioncard0042-6629Electro-craftove...Ort:KanadaEMERSONPCM-6960057-01POSITIONINGSERVODRIVEMODULEOrt:KanadaKollmorgenServostarCDCB10551,1YrWarranty,1days...Ort:KanadaSIEMENS6SC6116-0AA00G600POWERMODULE,90DAYSWARR...Ort:KanadaNEWFUJIELECTRICIGBT1MBI50L-060OVERNIGHTSHIPPINGOrt:KanadaKollmorgenServostarCDCB06551,1YrWarranty,1days...Ort:KanadaNEWKollmorgenServostar603-AS,S60301,1YrWarranty,...KollmorgenServostarServodriveCR10661,PRD-B010R00E-..?.SIEMENSSINUMERIK840DE6FC5357-0BB11-0?AE0NCU571.2Ort:KanadaNEWPM50RSK060MITSUBISHIPM50RSK-060IGBTFastshipOrt:KanadaSIEMENS6SN1123-1AA00-0?LA1,NEXTDAYTOUSA&CANADA.....Ort:KanadaNEWMITSUBISHIIGBTQM75DX-HOVERNIGHTSHIPP***AILABLEOrt:KanadaNEWFUJIELECTRICIGBT2MBI100N-060OVERNIGHTSHIPPINGOrt:KanadaKollmorgenServostarSR20200FASTSHIP,1YRWarrantyOrt:KanadaKollmorgenServostar603-ASS603016MONTHWARRANTY...Ort:KanadaSIEMENSNCU-BOX6FC5247-0AA00-0?AA2SINUMERIK840D/DEOrt:KanadaNEWKollmorgenMTC306B1-S2C1ServoMotorFASTship***ai...Ort:KanadaNEWMITSUBISHIIGBTMG100J6ES50OVERNIGHTSHIP***AILAB...Ort:KanadaNEWMITSUBISHIIGBTCM150DY-12HS30FS112HS30FS1FastNEWIndramatMAC071B-0-PS-4-?C/095-A-0/WI520?LV/S001NEWFUJIELECTRIC2DI150M-120IGBTOVERNIGHTSHIPPINGSIEMENS6SN1123-1AA00-0?LA1RENOVATEDUNIT,WARRANTY,...NEWMITSUBISHIIGBTPM30CSJ060OvernightShiping***ail...KOLLMORGENSERVOSTARCB20560NEW,1YRWARRANTY,OVER...NEWMITSUBISHIIGBTCM200DY-12HS40F?S1OVERNIGHTSHIPRepairServiceforElectro-craftBRU-500DM-50,DM-25,DM.?..RepairServiceforElectro-craftIQ-2000PDM-30,PDM-20,.?..RepairSIEMENSSimodriveLT,E/R,FeedModule6SN11236S...NEWPRXIGBTKD224505OVERNIGHTSHIPPING***AILABLENEWKollmorgenServostardrive603,S60300,1YrWarranty...Vickers-Kollmor?genAcramaticServoAS10301,1YrWrtyNE...NEWTOSHIBAMG15G1AL3OVERNIGHTSHIPPINGNEWMG200H1AL2TOSHIBAIGBTMODULEOVERNIGHTSHIPPINGVickersAcramaticServoAS10302,1Rebuilt,YrWarranty,...MITSUBISHIIGBTCM400DY1-1Overnightship***ailableca...NEWFANUCA16B-1212-0531/06B404953POWERSUPPLYUNITKollmorgenPowersupplyunitPA5000,1YrWarranty,F...KollmorgenPOWERSUPPLYPSR4/5A-112-040?0FASTSHIPLENZEVECTORDRIVEINVERTER8200SERIESE82EV152_4C200EMERSONServodriveDINVERTERDIN3380110BREFURBISHEDNEWTYCOIGBTP480A03-MODULE,06087FASTSHIP***AIABLHEIDENHAIN1387-020-2048ENCODERgoodNEWMITSUBISHIELECTRICIGBTTM10T3B-HF2101AHF2101AKollmorgenServostarCDCB06561,1YrWarranty,1days...SIEMENS6RA7031-6FV62-0?-Z,SIMOREGDCMASTER,FastshipSIEMENS6SN1162-0BA02-0?AA2RADIALGEBLAESECOOLINGFANNEWTOSHIBAMIG30J103HIGBTModule,Call905-465-0346NEWInfineonIGBTFZ1200R16KF4OVERNIGHTSHIPPINGCompumotorDigiplanServoDriveBLH75BBLH75BParker1PSIEMENS6SN1123-1AB00-0?HA2=0HA1LTMODULE2X8AM...DYNAMICBRAKERESISTORBWD50007272OHM,850VDCFORK...TOSHIBAMG25J6ES40CompatibletoIEF260A2IGBTModulePersonalitymodulePM030BF4050QH-0forElectro-craftGIDDINGS&LEWISCENTURIONDS-100DS120,401-34201-22PersonalitymodulePM020BS4030PH-0forElectro-craftKollmorgenServostardriveCE20560,1YearWarranty,NE...KollmorgenSERVOSTARPROFIBUS011020900560CARDNEWMITSUBISHIIGBTQM200HA-2HOVERNIGHTSHIPPINGCompumotorS6-DriveSSeriesParkerStepperMotordriveNEWB***75GB120DN2IGBTModuleEUPECFASTSHIP***AILABLENEWKollmorgenServos
