T/CIET 123-2023
Basic Information
Scope
Scope: This document specifies the usage characteristics, product codes, examples, technical requirements, finished cables, test conditions, test items, and test methods, delivery lengths, marking, packaging, transportation, and storage requirements for halogen-free, low-smoke, flame-retardant, irradiated cross-linked polyolefin insulated and sheathed photovoltaic cables for shallow-water applications with a rated voltage of AC U0/U: 0.6/1kV and DC 1500V. This document applies to DC-side photovoltaic modules in photovoltaic power generation systems, parallel cables between modules and from modules to DC distribution boxes (combiner boxes), and cables from DC distribution boxes to inverters. It can also be used for AC application cables connecting inverters to power grids. This document applies to photovoltaic cables with special requirements for waterproof performance and pressure resistance in fishery-photovoltaic hybrid systems. This document applies to photovoltaic cables laid by direct burial method. This document applies to photovoltaic cables laid by flexible bracket and steel cable suspension method. Other cables with waterproof requirements can refer to this document for implementation. **Main technical content**: This document specifies the usage characteristics, product codes, examples, technical requirements, finished cables, test conditions, test items and test methods, delivery lengths, marking, packaging, transportation, and storage requirements for halogen-free, low-smoke, flame-retardant, irradiated cross-linked polyolefin insulated and sheathed photovoltaic cables for shallow-water applications with a rated voltage of AC U0/U: 0.6/1kV and DC 1500V.
