二 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(zhì))之間的電壓有效值。
U―多芯電纜(電線)或單芯電纜(電線)系統(tǒng)任一兩相導(dǎo)體之間的電壓有效值。
當(dāng)電纜(電線)使用于交流系統(tǒng)時(shí),電纜(電線)的額定電壓至少應(yīng)等于該系統(tǒng)的標(biāo)稱電壓。當(dāng)使
用于直流系統(tǒng)時(shí),該系統(tǒng)的標(biāo)稱電壓應(yīng)不大于電纜(電線)額定電壓的 1.5 倍。
系統(tǒng)的工作電壓應(yīng)不大于系統(tǒng)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. 【ZC-FGR、ZR-KGGP22阻燃系列+硅橡膠+鎧裝高溫電纜ZR-KGGP22電纜結(jié)構(gòu)】
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.
