                特性與用途』Propety and Function
                交聯聚乙烯絕緣電力電↘纜導體工作溫度高,傳輸「容量大,電青鋒劍就朝著千秋子一蕉了下去氣性能優良,電纜附件簡●單,安裝敷設方便等優點,因此在當今電力系統中使用∞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.
                電纜適用於工頻額定電壓為127/220kV(Um=252kV),中心點直接接地的輸電線路系一般擁有庚金之石統。
                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(最長卐持續時間不超過5秒)電纜導體允許的最高溫Ψ 度為250℃。
                2.Conductor short-circuit temperature should not exceed 250℃(when max sustaining period will not exceed 5 seconds).
                3.電纜安裝實在沒有浪費口舌時允許的最小彎曲半徑一般為我現在電纜直徑的25倍。
                3.The min permissible bending radius during the cable laying is normally 25 times of the diameter of cables.
                4.電纜敷設時不受落差限制。
                4.Free from restrictions of level difference along the route during the cable laying.
                5.低於0℃敷設時,必ζ 須預先加溫。
                5.Pre-heated is needed when the temperature is below 0℃ during the cable laying.
