Abstract：With the development of the key technology,the“PEDF technology”to realize the “carbon peaking and carbon neutrality”goals,there is an urgent need for DC distribution cables to accompany building DC distribution systems. Through the sorting of DC cables for buildings in research，development and application and other aspects,the application status and existing problems of cables for DC distribution systems are analyzed,and it is proposed that special DC cables should be used for building DC distribution systems.

Key words：PEDF system;DC distribution system;AC cable;DC cable;cable withstand voltage test;single‑core;multi‑core;cable laying

摘　要：随着实现“双碳”目标关键技术“光储直柔技术”的发展，建筑直流配电系统亟需与之配套的直流配电电缆。通过对建筑直流电缆在研发和应用等方面的梳理，分析直流配电系统电缆应用现状和存在问题，提出建筑直流配电系统应采用专用的直流电缆。
