摘要:本文分析了铝合金电力电缆的优点,介绍在工程设计中如何选用铜芯电缆和铝合金电缆国家相关规范,结合公路工程配电设计的特点,得出如下结论:铝合金电力电缆不适合应用在如消防设施等供电等级要求较高的场合,适合应用于供电等级要求较低的场合,如隧道营运工况控制风机供电电力电缆,隧道照明低压主干电缆、道路照明主干电缆、监控外场设备供电电缆等;并对铝合金电力电缆的施工和验收提出技术要求。探索铝合金电缆在公路工程配电设计中的应用,响应国家节能减排,具有重要意义。

Abstract: This paper summarizes advantages and disadvantages of the aluminum cable,extracts relative specification of how to select the copper cable and the aluminum cable in engineering design,combines with the characteristics of road engineering power distribution design,draws the following conclusion: the aluminum cable is not suitable for application in power rating situations that require high such as fire protection facilities,suitable for application in power rating situations that require low such as power supply cable of the operating control of fan in tunnel,power supply main low cable of lighting of tunnel and road,power supply cable of Monitoring facilities outside tunnel,and put forward to technical specification construction and inspection of the aluminum cable. To explore the application of aluminum cable in road engineering power distribution design,in response to the national energy-saving emission reduction policies,it is of important significance to.
