【Abstract】 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.更多还原
