According to the requirements of the “Notice on Printing and Distributing the First Batch of Association Standards Formulation and Revision Plans in 2018” (Jianbiao Xiezi [2018] No. 015) issued by the China Construction Standardization Association, the China Academy of Building Research Co., Ltd. The "Technical Regulations for DC Lighting System" prepared by the Design and Research Institute Co., Ltd. and other organizations has been approved by the Association’s Building Environment and Energy Conservation Professional Committee and is now approved for publication. The number is T/CECS 705-2020, which will take effect on November 1, 2020. 

The "Standard" combines the characteristics of DC power supply, and gives relevant design requirements for power supply and distribution system, monitoring system, wiring system, lightning protection, etc., in coordination with the current relevant standards, and guides the engineering practice of DC lighting system. The preparation of "Standards" has important guiding significance for the design, installation, commissioning, acceptance and operation maintenance of DC lighting systems.

At the same time, this "Standard" is my country's first DC lighting system standard, which fills the gap in my country's DC lighting system standard and reaches the international advanced level.
