摘要
在城市电网建设中,电缆排管敷设方式具有优越性。建立了电缆排管敷设的载流量计算模型,计算得出了不同敷设方式下电缆的载流量;有针对性地就新型电缆保护管材在工程中的应用提出设计思路;对排管电缆工井的数量、长度、布置等要素分析论证,提出了解决工井排水的措施。文章可为电缆排管工程的设计和施工提供参考。
Power cables laid in pipes are widely used in urban power grid construction. This paper established a calculation mode for cable ampacity, and obtained results in accordance with different installation methods. Furthermore, design methods for the application of novel cable protecting tubes were proposed, and solutions to the drainage problem of manholes were carried out considering the number, the length and the arrangement. This paper has a practical significance for design and construction of power cables laid in pipes.
