電纜使用特性  Application

1 額定電壓U0/U為450/750V～600/1000V

U0―任一主絕緣和“地”（金屬屏蔽、金屬套或周圍介質）之間的電壓有效值。

U―多芯電纜（電線）或單芯電纜（電線）系統任一兩相導體之間的電壓有效值。

當電纜（電線）使用于交流系統時，電纜（電線）的額定電壓至少應等于該系統的標稱電壓。當使

用于直流系統時，該系統的標稱電壓應不大于電纜（電線）額定電壓的 1.5 倍。

系統的工作電壓應不大于系統額定電壓的 1.5 倍。

Rated voltage U0/U should be 450/750V～600/1000V

U0―Valid value of the voltage between main insulated conductor and earthing (metal shield, metal

sheath or environment dielectric).

U―Valid value of voltage between any two phases conductor in multicore cable or single cable

system.

When AC. System is applied, the rated voltage of cable should be at least equal to the nominal

voltage of the system . When DC. System is applied, the nominal voltage of this system should

not be more than the rated voltage of the system by 1.5 times.
