本指南提供的一般信息可用于将额定电压为5至46 kV的挤压绝缘电缆的初始采购成本降至最低。每个设计变量都可能对电缆和电缆上使用的附件的性能产生影响。指定电缆的人必须仔细考虑每个设计变量或选项，以及这些项目对电缆系统的整体性能的影响，然后才能做出任何决定。本文件中确定的设计变量和选项不应视为AEIC的建议。这些变量仅列出以允许用户在尝试降低其电缆的初始购买成本时考虑一些选项。用户应该考虑任何变量是否可以减少长时间。 在采用本文件中列出的任何项目之前，其地下电缆系统的长期性能。建议用户在制定新的电缆规范之前，参考AEIC CG10《5至46 kV挤压电力电缆规范制定指南》和AEIC CS8《5至46 kV挤压介质屏蔽电力电缆规范》。为了最大限度地降低电缆成本，用户需要了解可用的设计、标签、包装、测试和鉴定选项，以及这些选项可能对电缆成本和性能的影响。用户还需要了解这些选项对电缆制造商的影响。本指南的其余部分旨在帮助用户更好地理解这些选项。

This guide provides general information that can be used to minimize the initial purchase cost of extruded dielectric cable rated 5 through 46 kV. Each design variable may have an impact on the performance of both the cable and the accessories used on the cable. The person specifying cable must carefully consider each design variable or option and the impact these items may have on the overall performance of the cable system before making any decisions.The design variables and options identified in this document shall not be considered to be recommendations of the AEIC. These variables are listed only to allow the user to be aware of some options to consider when attempting to reduce the initial purchase cost of their cable. The user should consider whether any variable might reduce the long-term performance of their underground cable systems before adopting any of the items listed in this document.It is suggested that prior to developing a new cable specification, the user refer to AEIC CG10, "Guide for Developing Specifications for Extruded Power Cables Rated 5 through 46 kV" and AEIC CS8, "Specification for Extruded Dielectric Shielded Power Cables Rated 5 through 46 kV".To minimize the cost of cable, the user will need to know the design, labeling, packaging, testing, and qualification options that are available and the impact these options may have on the cost and performance of cable. The user also needs to understand the impact these options have on the cable manufacturer. The remaining sections of this guide are provided to assist the user in better understanding these options.
