Features: This standard was revised according to the requirements of the original State Economic and Trade Commission's "Notice on Issuing the 2001 Annual Plan for the Formulation and Revision of Power Industry Standards" (No. 44 of State Economic and Trade Commission on Power Industry [2001]), and it revises DL5025-1993. This standard specifies the design requirements for PDH (Plesiochronous Digital Hierarchy) and SDH (Synchronous Digital Hierarchy) digital microwave relay communication circuits, the basic requirements for communication system routes, section design, and technical requirements such as microwave station design.
This standard is applicable to newly constructed PDH microwave communication trunk projects with a capacity of secondary groups and above, as well as SDH microwave relay communication inter-provincial and intra-provincial trunk engineering design. For expansion, renovation projects, and small-scale microwave communication engineering design, it can be referred to for implementation.
