Scope

Scope: This document specifies the evaluation index system, evaluation methods, and grade classification for the evaluation of the "Leader" standard for wind power cables. It applies to the evaluation of enterprise standard levels for torsion-resistant soft cables for wind power generation with a rated voltage of 1.8/3kV and below, and for torsion-resistant soft cables for wind power generation with a rated voltage of 6kV (Um=7.2kV) to 35kV (Um=40.5kV). Relevant institutions can refer to this document when formulating "Leader" evaluation schemes for enterprise standards, and enterprises can also use it as a reference when developing their own enterprise standards. Main Technical Content: 4.2 Classification of Evaluation Indices 4.2.1 The indicators included in the "Leader" standard for wind power cables are divided into basic indicators, core indicators, and innovative indicators. 4.2.2 Basic Indicators 4.2.2.1 Rated voltage: For torsion-resistant soft cables for wind power generation with a rated voltage of 1.8/3kV and below, the indicators include conductor DC resistance, insulation thickness, sheath thickness, cable outer diameter, tensile strength and elongation at break, heat elongation, pressure test, sheath oil resistance, low-temperature tensile strength, sheath tear resistance, and low-temperature tensile strength. 4.2.2.2 Rated voltage: For torsion-resistant soft cables for wind power generation with a rated voltage of 6kV to 35kV, the indicators include conductor DC resistance, insulation thickness, shielding thickness, sheath thickness, tensile strength and elongation at break, heat elongation, insulation ozone resistance, sheath oil resistance, insulation water absorption, sheath tear resistance, low-temperature tensile strength, artificial climate aging, salt spray test, bending and partial discharge, tanδ, thermal cycling and partial discharge, impact voltage, and pressure test, as well as 4h voltage. 4.2.3 Core Indicators 4.2.3.1 For t
