注:防腐型的计算重量,在表中规定值上增加防腐涂料的重量(钢芯涂料增加20%,其它增加5%)。
Note: Corrosion-based weight calculation, the value specified in the table to add the weight of anti-corrosion coating (steel core coatings to increase 20%, other 5%).
 
五、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.
 
六、订货须知  Ordering Information
订货时,用户应注明所订产品的型号、规格、数量及产品所执行的标准等。
如:订购钢芯铝绞线50/8 mm2 20吨。可写为:LGJ-50/8 mm2 20 GB/T1179
Please indicate the typesizenumber and product standard when ordering .
For example :if ordering 20T steel-reinforced aluminum stranded conductor with a cross-sectional area of 50/8 mm2  can indicated as : LGJ-50/8mm2 20T GB/T1179.
