8、无电磁,防火电缆与信 、控制等线缆在相同竖井中敷设时.防火电缆在铜护套的屏蔽下.不会对信 控制线缆传输的信息产生。
9、安全性好,防火电缆除了在火焰中正常供电,起动灭火设备,火灾损失。同时对人身安全亦可靠,其铜护套是良导体,是的接地线,且连续到电缆全长,大大了接地保护灵敏度与可靠性。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河北邯郸回收废旧电缆废铜铝线回收迅速结算
