Scope

Scope: This document specifies the evaluation index system, evaluation methods, and grade classification for the "Leader" standard evaluation of power cable accessories. It applies to the evaluation of enterprise standard levels for power cable accessories with rated voltages of 35kV and below, 110kV, 220kV, and 500kV. Enterprises can refer to it when formulating enterprise standards, and relevant institutions can use it as a reference when developing "Leader" evaluation schemes for enterprise standards. Main Technical Content: 4.2 Classification of Evaluation Indices 4.2.1 The indicators included in the "Leader" standard for power cable accessories are divided into basic indicators, core indicators, and innovative indicators. 4.2.2 Basic Indicators 4.2.2.1 Basic indicators for 35kV and below power cable accessories include constant-voltage load cycling, short-circuit thermal stability (shielding), short-circuit thermal stability (conductor), short-circuit dynamic stability, moisture test (indoor terminals), and salt spray test (outdoor terminals). 4.2.2.2 Basic indicators for 110kV power cable accessories include insulation strength in outdoor terminal rain-simulation AC voltage test, volume resistivity of semiconductive rubber bands (before aging) at 23°C, short-time AC breakdown strength of epoxy resin cured (glue) bodies, and volume resistivity of epoxy resin cured (glue) bodies at 23°C, as well as the thermal deformation temperature of epoxy resin cured (glue) bodies. 4.2.2.3 Basic indicators for 220kV power cable accessories include insulation strength in outdoor terminal rain-simulation AC voltage test, volume resistivity of semiconductive rubber bands (before aging) at 23°C, short-time AC breakdown strength of epoxy resin cured (glue) bodies, and volume resistivity of epoxy resin cured (glue) bodies at 23°C, as well as the thermal deformation temperature of epoxy resin cured (glue) bodies. 4.2.2.4 Basic indicators for 500kV power cable accesso
