Scope

Scope: This document specifies the evaluation index system, evaluation methods, and grade classification for the "Leader" standard evaluation of oil equipment cables. It applies to electric submersible pump cables rated at 3.6/6 kV and below, and to the horizontal evaluation of load-bearing detection cables for oil and gas drilling and extraction equipment according to enterprise standards. Relevant institutions can refer to this document when formulating "Leader" evaluation programs for enterprise standards, and enterprises can use it as a reference when developing their own standards. Main Technical Content: 4.2 Classification of Evaluation Indices 4.2.1 The indicators included in the "Leader" standard for oil equipment cables are divided into basic indicators, core indicators, and innovative indicators. 4.2.2 Basic Indicators 4.2.2.1 For electric submersible pump cables rated at 3.6/6 kV and below, the basic indicators include: average insulation thickness, insulation resistance, voltage withstand performance, leakage current, tensile strength before insulation aging, tensile strength after insulation aging, elongation at break before insulation aging, elongation at break after insulation aging, and 4-hour high-voltage withstand test. 4.2.2.2 For load-bearing detection cables for oil and gas drilling and extraction equipment, the basic indicators include: structural dimensions and appearance inspection, insulation resistance at 20°C, tensile performance, low-temperature winding, and voltage withstand performance. 4.2.3 Core Indicators 4.2.3.1 For electric submersible pump cables rated at 3.6/6 kV and below, the core indicators include: DC resistance of the conductor at 20°C, thickness at the thinnest point of the insulation, rate of change in tensile strength after insulation aging, and rate of change in elongation at break after insulation aging, as well as maximum elongation under heat extension test. 4.2.3.2 For load-bearing detection cables f
