标准范围

IEC 61238-1-2:20 18适用于额定电压高达1 kV(Um=1,2 kV)的电力电缆的绝缘穿孔连接器，例如根据IEC 60502-1或安装在建筑物中的其他埋地电缆和电缆，具有a)符合IEC 60228的导体，铜的标称横截面积在2.5 mm2至300 mm2之间，铝的标称横截面积在16 mm2至500 mm2之间，b)不超过绝缘材料特性的最高连续电缆温度。本文件不适用于架空线路导线连接器，也不适用于带滑动触点的连接器。本文件的目的是定义适用于铜或铝导体电力电缆绝缘穿孔连接器的型式试验方法和要求。参考方法是在未使用的绝缘导线上进行试验。第一版与IEC 61238-1-1和IEC 61238-1-3一起取消并取代了IEC 61238-1:20 03。本版本包括以下与IEC 61238--1:20 03相关的重大技术变更:a)范围已扩大到涵盖从10 mm2到2.5 mm2的导体的连接器，并且已限制为铜导体的300 mm2和铝导体的500 mm2，因为对于较大的导体，IPC的测试经验和应用很少。横截面面积。b)引入了新的机械类别，以满足对不受机械力影响的连接器的需求。c)电气测试方法已更新，以考虑绝缘参考导体的温度。d)对于短路试验，更新了计算方法和要求。e)对于机械试验，更新了方法和要求。f)介绍了多芯连接器测试的不同测试方案。g)介绍了使用活负载拾取对绝缘穿孔连接器进行预处理的测试方案。

IEC 61238-1-2:2018 applies to insulation piercing connectors for power cables for rated voltages up to 1 kV (U_m = 1,2 kV), for example according to IEC 60502-1 or other buried cables and cables installed in buildings, having
a) conductors complying with IEC 60228 having nominal cross-sectional areas between 2,5 mm² and 300 mm² for copper and between 16 mm² and 500 mm² for aluminium,
b) a maximum continuous cable temperature not exceeding the insulation material properties.
This document is not applicable to connectors for overhead line conductors nor to connectors with a sliding contact.
The object of this document is to define the type test methods and requirements, which apply to insulation piercing connectors for power cables with copper or aluminium conductors. The reference method is to perform the tests on unused insulated conductors.
This first edition, together with IEC 61238-1-1 and IEC 61238-1-3, cancels and replaces IEC 61238-1:2003.
This edition includes the following significant technical changes with respect to IEC 61238--1:2003:
a) The scope has been widened to cover connectors for conductors from 10 mm² down to 2,5 mm² and has been limited to 300 mm² for copper conductors and 500 mm² for aluminium conductors because test experience and applications for IPC are rare for conductors of larger cross-sectional areas.
b) A new mechanical class has been introduced to satisfy the demand for connectors subjected to no mechanical force.
c) The electrical test method has been updated in order to take into consideration the temperature of the insulated reference conductors.
d) For the short-circuit test, the method of calculation and requirements have been updated.
e) For the mechanical test, the methods and requirements have been updated.
f) Different test proposals for multicore connector testing have been introduced.
g) A test proposal for pre-conditioning using live load pickup for insulation piercing connectors has been introduced.
