电缆使用特性  Application

1 额定电压U0/U为450/750V～600/1000V

U0―任一主绝缘和“地”（金属屏蔽、金属套或周围介质）之间的电压有效值。

U―多芯电缆（电线）或单芯电缆（电线）系统任一两相导体之间的电压有效值。

当电缆（电线）使用于交流系统时，电缆（电线）的额定电压至少应等于该系统的标称电压。当使

用于直流系统时，该系统的标称电压应不大于电缆（电线）额定电压的 1.5 倍。

系统的工作电压应不大于系统额定电压的 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.
