Scope

Scope: This document specifies the evaluation index system, evaluation methods, and grade classification for the "Leader" standard evaluation of 220kV to 500kV extra-high voltage cross-linked cables. This document is applicable to the evaluation of enterprise standards for 220kV, 330kV, and 500kV cross-linked polyethylene insulated power cables. Relevant institutions may refer to it when formulating enterprise standard evaluation schemes, and enterprises may use it as a reference when establishing their own enterprise standards. Main Technical Content: 4.2.1 The "Leader" standard for 220kV to 500kV extra-high voltage cross-linked cables includes basic indicators, core indicators, and innovative indicators. 4.2.2 Basic Indicators 4.2.2.1 Basic indicators for 220kV cross-linked polyethylene insulated power cables include conductor DC resistance, insulation micro-pores and impurities, semiconductive shielding layer-insulation interface micro-pores and protrusions, tgδ, semiconductive shielding resistivity, mechanical properties of the outer sheath before and after aging, capacitance, partial discharge, AC voltage, PVC sheath thermal decomposition, outer sheath high-temperature pressure, black polyethylene sheath carbon black content, outer sheath DC voltage, lightning impulse and subsequent AC voltage, thermal cycling voltage, combustion performance, water permeability, and components of the cable with longitudinal metallic foil or metal strips adhered to the outer sheath. 4.2.2.2 Basic indicators for 330kV cross-linked polyethylene insulated power cables include conductor DC resistance, tgδ, semiconductive shielding resistivity, mechanical properties of the outer sheath before and after aging, capacitance, partial discharge, AC voltage, PVC sheath thermal decomposition, outer sheath high-temperature pressure, black polyethylene sheath carbon black content, outer sheath DC voltage, lightning impulse and subsequent AC voltage, thermal cycling voltage, combustion
