Scope

Scope: This document specifies the evaluation index system and evaluation methods for the quality and enterprise standard level assessment of 66kV to 110kV high-voltage cross-linked cables, as well as their grading standards. This document is applicable to the quality and enterprise standard level assessment of rated voltage 66kV to 110kV high-voltage cross-linked cables. Relevant institutions may refer to and use it when conducting quality grading and enterprise standard level evaluation, as well as "leader" assessments and related certifications. Enterprises may also refer to this document when formulating their own enterprise standards. Main technical content: 4.2 Evaluation Indices 4.2.1 Basic Indices - For 66kV cross-linked polyethylene insulated power cables, the basic indices 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, lightning impulse and subsequent AC voltage, thermal cycling voltage, combustion performance, water permeability, and components of the cable with longitudinally wrapped metallic foil or metallic tape adhered to the outer sheath. - For 110kV cross-linked polyethylene insulated power cables, the basic indices include conductor DC resistance, insulation micro-pores and impurities, semiconductive shielding layer-insulation interface micro-pores, protrusions, tgδ, semiconductive shielding resistivity, outer sheath mechanical properties 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 w
