      注:1、絞線重量是按密度為8.9kg/dm3及平均節距比計算的。
      2、參考適用于風速為0.6m/s,環境溫度為35℃的日照作用及架空輸電絞線最高溫度為70℃的60HZ及以下的線路。在靜止空氣的特殊敷設情況下,載流量平均下降約30%。
      Note: The weight of stranded conductor is calculated with the density 8.9kg/dm3 and average lay ratio.
      Refer to the line ,the wind speed is 0.6m/s,the ambient temperature is 35℃,Max .temperature of aerial transmission strand is 70℃,60HZ and below .In the special laying situation of static air ,the capacity shall reduce about 30% in average.
       
      七、交貨長度 Delivery length
      1、絞線的交貨長度應符合表中規定。任一絞線的交貨長度允許偏差為±5%。每一合同的總交貨量中,允許有5%不小于三分之一標準交貨長度的短段交貨。根據雙方協議,允許以任何長度的短段交貨。
      The delivery length of stranded conductors shall be as stipulated in the tables.The allowed tolerance for delivery length of any strands is within 5%.With the amount of short strands being 5% of  the total length signed in the contract .the length for each short strand shall be not less than 1/3 of the standard delivery one.The delivery length can be decided through negotiation by both sides
      2、絞線應成盤交貨,并妥善包裝。外段絞線允許成圈交貨,每圈至少包扎三處,并妥善包裝。
      The strands shall be delivery in drum and packed carefully .The short strands shall be deliveried in coiling and tied up at least three points and packed carefully.
       
      八、訂貨須知Ordering method
      訂貨時,用戶應注明所訂產品的型號、規格、數量及產品所執行的標準等。
      Please indicate the type、size、number and product standard when ordering .
