IEC TR 60865-2:2015（E）显示了IEC 60865-1中所述短路引起的机械和热效应计算程序的应用。因此，本技术报告是对IEC 60865-1的补充。然而，它不会改变该出版物中给出的标准化程序的基础。第二版取消并取代1994年出版的第一版，构成技术修订版。它包括以下变化。对自动重合闸和刚性导体的测定值进行了修订。柔性导体布置的配置已经改变。已包括跨中吊杆对跨度的影响。对于垂直电缆连接，现在可以计算下固定点上的位移和拉力。增加了由于拉伸力引起的地基荷载的附加建议。 已删除确定热等效短路电流的子条款（现在是IEC 60909-0:2001的一部分）。对标准IEC 60865-1:2011进行了重组，并对一些符号进行了更改，以符合国际标准的概念特征。

IEC TR 60865-2:2015(E) shows the application of procedures for the calculation of mechanical and thermal effects due to short circuits as presented in IEC 60865-1. Thus, this technical report is an addition to IEC 60865-1. It does not, however, change the basis for standardized procedures given in that publication. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision. It includes the following changes. The determinations for auto reclosure together with rigid conductors have been revised. The configurations in cases of flexible conductor arrangements have been changed. The influence of mid-span droppers to the span has been included. For vertical cable-connection the displacement and the tensile force onto the lower fixing point may be calculated now. Additional recommendations for foundation loads due to tensile forces have been added. The subclause for determination of the thermal equivalent short-circuits current has been deleted (is part of IEC 60909-0:2001 now). The standard IEC 60865-1:2011 has been reorganized and some of the symbols have been changed to follow the conceptual characteristic of international standards.
