The bending radius of a single-core cable should not less than 20 times of the cable diameter.
The bending radius of a single-core cable should not less than 15 times of the cable diameter.
電纜額定電壓的選擇 Voltage designation
· 電纜的額定電壓應適合于電纜系統的運行狀況，用U0/U（Um）kv表示。
U0－電纜設計用的導體對地或金屬屏蔽之間的額定工頻電壓；
U－電纜設計用的導體間的額定工頻電壓；
Um－設備可承受的“zui高系統電壓”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:
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.
· 三相系統用電纜的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
U kv	U m kv	A 和 B 類系統 System categories A and B	C 類系統 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類系統──該類系統任何一相導體與地和接地導體接觸時，能在1min內與系統分離
B類系統──該類系統僅包括單相接地故障短時運行的條件，接地故障時間應不超過1h, 但在任何情況下，zui長不超過8h每年接地故障總持續時間不超過125h；
C類系統──不屬于A類、B類的系統。
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.
System categeory C──This category comprises all systems which do not fall into A and B
