摘　　要：本文分析及探讨了国家标准《GB/ T12 70 6 .1～ 3- 2 0 0 2和 GB/ T110 17.2 - 2 0 0 2》中提出的金属铜带搭盖绕包和铜丝与金属铜带的组合结构屏蔽形式的特性 ,计算分析短路电流通过屏蔽铜带 (丝 )The characteristics of the screen of wrapped copper tape with overlap and the composite screen of copper wire and tape specified in the national standards GB/T 12707.1~3-2002 and GB/T 11017.2-2002 are presented. The temperature rise due to the short circuit current flowing through the screening copper tape (wire) was calculated. The reason of the requirement for the interval between windings of the copper tape or wire in open spirals was analyzed.
