Scope

Main Technical Content: 1. This document primarily specifies the rated voltage, model, specifications, and product representation methods for extruded plastic-insulated power optical cables used in distribution networks with rated voltages ranging from 3.6/6 kV to 26/35 kV. It also covers materials, technical requirements, marking, delivery length, testing requirements, inspection rules, packaging, transportation, storage, and post-installation testing. 2. There are multiple types of optical fibers. Based on the actual application conditions of 6-35 kV optical cables, this document provides typical types and specifies that other types can be selected according to project needs (see Article 5.1.5). 3. According to research, the insulation material for 6-35 kV optical cables is primarily extruded cross-linked polyethylene (XLPE). This document stipulates that the insulation material must be XLPE (see Article 6.1), and all provisions in this document are based on this research principle. 4. Although 6-35 kV cables are commonly referred to as medium-voltage cables, for optimization, the series models are denoted as OPC—, with the "medium-voltage" meaning being indicated by the voltage. 5. Regarding the nominal cross-section of conductors, the document provides a non-recommended range based on actual project situations (see Table 6). 6. For optical cables with halogen-free requirements, it stipulates that the insulation, sheath (including the sheath of the optical unit), filler, and isolation sleeve (inner lining) must not contain halogens (see Articles 7.3.1, 7.6.5, 7.7.2, and 7.7.3.2). 7. In recent years, fire safety requirements for high-rise buildings and densely populated areas involving public safety and human life have become increasingly stringent. Design specifications now mandate B1-level flame retardancy, requiring compliance with the B1 flame retardancy requirements of GB 31247 (see Article 5.1.2). 8. For the outer sheath of optical units, con
