標準Stands
GB/Z 18890-2002《額定電壓220kV(Um=252kV)交聯(lián)聚乙烯絕緣電力電纜及其附件》

IEC 62607:1999 《額定電壓150kV(Um=170kV)以上至550kV(Um=550kV)擠出絕緣電力電纜及其附件-試驗方法和要求》
 
特性與用途Propety and Function
交聯(lián)聚乙烯絕緣電力電纜導(dǎo)體工作溫度高,傳輸容量大,電氣性能優(yōu)良,電纜附件簡單,安裝敷設(shè)方便等優(yōu)點,因此在當今電力系統(tǒng)中使用廣泛。
Cross-linked polyethylene insulated power cable are featured with high allowable working temperature of conductor,huge transmission capacity,excellent electric properties,simple cable accessories and convenient installment and laying, so that they are widely used in the power system today. 
電纜適用于工頻額定電壓為127/220kV(Um=252kV),中心點直接接地的輸電線路系統(tǒng)。
The cable can be applied to the neutral-point solid grounded power transmission line system with A.C.rated voltage 127/220kV(Um=252kV).
 
使用特性Properties of Applition
1.電纜正常運行時導(dǎo)體允許的長期最高溫度為90℃
1.During the normal operation of cables,the max permissible continuous operation temperature of conductor should not exceed 90℃
2.短路時(最長持續(xù)時間不超過5秒)電纜導(dǎo)體允許的最高溫度為250℃。
2.Conductor short-circuit temperature should not exceed 250℃(when max sustaining period will not exceed 5 seconds).
3.電纜安裝時允許的最小彎曲半徑一般為電纜直徑的25倍。
3.The min permissible bending radius during the cable laying is normally 25 times of the diameter of cables.
4.電纜敷設(shè)時不受落差限制。
4.Free from restrictions of level difference along the route during the cable laying.
5.低于0℃敷設(shè)時,必須預(yù)先加溫。
5.Pre-heated is needed when the temperature is below 0℃ during the cable laying.
