Scope

Scope: This document specifies the evaluation index system, evaluation methods, and grade classification for the evaluation of the "Leader" standard of submarine cables. It applies to the evaluation of enterprise standard levels for rated voltages of 110kV and below, as well as 220kV submarine cables. Relevant institutions may refer to it when formulating enterprise standard evaluation schemes, and enterprises may 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 evaluation indices of the "Leader" standard for submarine cables include basic indices, core indices, and innovative indices. 4.2.2 Basic Indices 4.2.2.1 For 110kV and below submarine cables, the basic indices include voltage test voltage, conductor structure, conductor resistance, insulation thickness, metal sheath thickness, diameter/thickness of armoring metal wires, resistance of conductor shielding and insulation shielding, watertightness of fiber optic units, XLPE insulation micro-impurities and pores/protrusions at the interface between the semiconducting shielding layer and insulation layer, tensile strength and elongation at break of soft joints, resistance of semiconducting sheath (if any), sensitivity of partial discharge test for submarine cable bodies, and insulation eccentricity. 4.2.2.2 For 220kV submarine cables, the basic indices include voltage test voltage, conductor structure, conductor resistance, insulation thickness, metal sheath thickness, diameter or thickness of armoring metal wires, resistance of conductor shielding and insulation shielding, watertightness of fiber optic units, XLPE insulation micro-impurities and pores/protrusions at the interface between the semiconducting shielding layer and insulation layer, tensile strength and elongation at break of soft joints, resistance of semiconducting sheath (if any), sensitivity of partial discharge test for submarine cable b
