T/SDWCIA 0009-2021 "Leader Standard Evaluation Requirements for Submarine Cables"

Scope

Scope: This document specifies the evaluation index system, evaluation methods, and grade classification for the evaluation of submarine cable "Leader" standards. 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 programs, 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 submarine cable "Leader" standards include basic indices, core indices, and innovative indices. 4.2.2 Basic Indices 4.2.2.1 The basic indices of 110kV and below submarine cables include voltage test voltage, conductor structure, conductor resistance, insulation thickness, metal sheath thickness, diameter/thickness of armoring metal wires, conductor shielding and insulation shielding resistivity, water tightness of fiber units, XLPE insulation micro-pore impurities, and micro-pores and protrusions at the interface between the semiconducting shielding layer and the insulation layer, tensile strength and elongation at break of soft joints, resistivity of semiconducting sheaths (if any), sensitivity of partial discharge tests on submarine cable bodies, and insulation eccentricity. 4.2.2.2 The basic indices of 220kV submarine cables include voltage test voltage, conductor structure, conductor resistance, insulation thickness, metal sheath thickness, diameter or thickness of armoring metal wires, conductor shielding and insulation shielding resistivity, water tightness of fiber units, XLPE insulation micro-pore impurities, and micro-pores and protrusions at the interface between the semiconducting shielding layer and the insulation layer, tensile strength and elongation at break of soft joints, resistivity of semiconducting sheaths (if any), sensitivity of partial discharge tests on subma
