T/SDWCIA 0008-2021 "Leader standard evaluation requirements for photovoltaic cables"

Scope

Scope: This document specifies the evaluation index system, evaluation methods, and grade classification for the "Leader" standard evaluation of photovoltaic cables. This document applies to the series cables between photovoltaic modules and modules in the DC side of photovoltaic power generation systems, the parallel cables between series cables and from series cables to DC distribution boxes (current collectors), and the cables from DC distribution boxes to inverters. It can also be used for enterprise-level evaluation of AC application cables used to connect inverters to the power grid. Relevant institutions can refer to this document when formulating enterprise-level "Leader" evaluation schemes. Enterprises can also refer to this document when formulating their own enterprise standards. Main technical content: 4.2 Classification of evaluation indices 4.2.1 The indices included in the "Leader" standard for photovoltaic cables are divided into basic indices and core indices. 4.2.2 Basic indices include conductor DC resistance, finished product voltage (AC), finished product voltage (DC), halogen-free performance, insulation thickness, sheath thickness, low-temperature impact, low-temperature bending, low-temperature tensile strength, and single-wire vertical combustion. 4.2.3 Core indices include artificial climate aging performance, smoke density, and salt spray aging resistance. Core indices are divided into three grades: advanced level, equivalent to a 5-star level in the enterprise standard ranking list; average level, equivalent to a 4-star level in the enterprise standard ranking list; and baseline level, equivalent to a 3-star level in the enterprise standard ranking list.
