注:1、绞线重量是按密度为8.9kg/dm3及平均节距比计算的。
2、参考适用于风速为0.6m/s,环境温度为35℃的日照作用及架空输电绞线最高温度为70℃的60HZ及以下的线路。在静止空气的特殊敷设情况下,载流量平均下降约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、交货长度 Delivery length
1、绞线的交货长度应符合表中规定。任一绞线的交货长度允许偏差为±5%。每一合同的总交货量中,允许有5%不小于三分之一标准交货长度的短段交货。根据双方协议,允许以任何长度的短段交货。
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、绞线应成盘交货,并妥善包装。外段绞线允许成圈交货,每圈至少包扎三处,并妥善包装。
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、订货须知Ordering method
