高压电缆的选择指南

[中文适用范围]： 本标准旨在为具有挤出绝缘的交流高压电缆及电缆系统的选择提供指导，主要用于额定电压超过 U = 1 kV 的三相交流系统（在本标准中，“高压”一词用于涵盖任何高于 1 kV 的电缆）。水下电缆不在范围内。提供了导体截面、绝缘水平和电缆构造要求的选择指导。此外，还汇总了使适当选择成为所需的信息。纸绝缘电力电缆不在本标准的电缆系统选择考虑范围内。但是，在选择与现有纸绝缘电缆连接的挤出绝缘电缆时，应特别考虑其适当的兼容性、附件和运行特性。在可能影响高压电缆及其应用选择的环境问题方面，提到了相关方面。 [外文原描述]： IEC 60183:2015 gives guidance in the selection of a.c. high-voltage cables and cable systems with extruded insulation and mainly to be used on three-phase alternating systems operating at voltages exceeding U = 1 kV (in this standard the term high voltage is used to cover any cable above 1 kV). Submarine cables are not included in the scope. Guidance is given in the selection of the conductor size, insulation level and constructional requirements of cable to be used. In addition, information necessary to enable the appropriate selection to be made is summarized. Paper insulated power cables are not considered in this standard for their selection into cable systems. However, when selecting cables with extruded insulation to be connected together with existing paper insulated cables, particular consideration for their proper compatibility, accessories and operational characteristics should be made. Environmental aspects are mentioned at the level at which they may influence the selection of high-voltage cables and their application. This third edition cancels and replaces the second edition, published in 1984, and its Amendment 1 (1990) and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the scope has been changed to a.c. high-voltage cables and cable systems; - guidance relates to cables with extruded insulation; - submarine cables are not covered but cables laid in water are covered; - operation of systems with special bonding of the screen is covered; - there is guidance on accessories; - environmental aspects are addressed.
