Scope

Scope: This document specifies the evaluation index system, evaluation methods, and grade classification for the "Leader" standard evaluation of shallow-sea lake cables. This document is applicable to the evaluation of enterprise standards for shallow-sea lake cables. Relevant institutions can refer to it when formulating evaluation schemes for enterprise standards. Enterprises can also refer to it when formulating their own enterprise standards. Main technical content: 4.2 Evaluation Index Classification 4.2.1 The evaluation indexes for the "Leader" standard of shallow-sea lake cables are divided into basic indicators, core indicators, and innovative indicators. 4.2.2 Basic indicators include conductor resistance performance, voltage withstand performance, conductor structure, insulation thickness, non-metallic sheath thickness, copper strip (wire) shielding structure, aluminum-plastic composite sheath thickness, and armored metal wire (strip) structure. 4.2.3 Core indicators include partial discharge performance, cable insulation eccentricity, XLPE insulation thermal elongation, insulation thermal shrinkage, winding performance, tension and bending performance, longitudinal waterproofing performance, and radial water permeability. The evaluation grades are as follows: - Advanced level: Corresponds to a 5-star level in the enterprise standard ranking list. - Average level: Corresponds to a 4-star level in the enterprise standard ranking list. - Benchmark level: Corresponds to a 3-star level in the enterprise standard ranking list. 4.2.4 Innovative indicators include insulation resistance to water tree growth and the integrity of aluminum-plastic composite sheaths. There are no grade divisions for these indicators. Enterprises are encouraged to add relevant innovative indicators related to product performance and consumer concerns when conditions permit.
