YJV电缆价格

​

·YJV电缆价格 电缆的额定电压应适合于电缆系统的运行状况，用U0/U（Um）kv表示。 U0－电缆设计用的导体对地或金属屏蔽之间的额定工频电压； U－电缆设计用的导体间的额定工频电压； Um－设备可承受的“zui高系统电压”的zui大值。 The rated voltage of the cable for a given applixation shall be suitable for the operating conditions in the system in which the cable is used,and is expressed in the form of U0/U（Um）kv Where: YJV电缆价格 U0－The rated power-frequency voltage between conductors and earth metallic screen ,for which the cable designed; U － The rated power-frequency voltage between conductos, for which the cable designed; Um－ The maximum value of the“highest system voltage”for which the equipment may beused. · 三相系统用电缆的U0值*如下表： The values of U0 recommened for cable to be used in three-phase systems are listed below: 　 U kv U m kv U 0 * kv A 和 B 类系统 System categories A and B C 类系统 Systems categories C 6 7.2 3.6 6 10 12 6 8.7 15 17.5 8.7 12 20 24 12 18 30 36 18 － 35 40.5 21 26 A类系统──该类系统任何一相导体与地和接地导体接触时，能在1min内与系统分离 B类系统──该类系统仅包括单相接地故障短时运行的条件，接地故障时间应不超过1h, 但在任何情况下，zui长不超过8h每年接地故障总持续时间不超过125h； C类系统──不属于A类、B类的系统。 System category A──This category comprises those systems in which any phase conductor that comes in contact with earth or an earth conductor. is disconnected from the system within 1 min. System category B ──This category comprises those system which,under faultconditions,are operated,are operated for ashorttimewith one phase earthed.This period should not exceed 1 h..Fora longer period, not exceeding 8h on any occasion, can be tolerated.The total duration of earth faults in any year should not exceed 125h.
