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 with a rated voltage of 3.6/6 kV and below, and to corrosion detection cables for oil and gas drilling and extraction equipment. Relevant institutions can refer to it when formulating enterprise standards for "Leader" assessments, 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 Rated voltage of 3.6/6 kV and below electric submersible pump cables: - Insulation average thickness - Insulation resistance - Withstand voltage performance - Leakage current - Insulation tensile strength before aging - Insulation tensile strength after aging - Insulation elongation before aging - Insulation elongation after aging - 4-hour high-voltage withstand voltage test 4.2.2.2 Corrosion detection cables for oil and gas drilling and extraction equipment: - Structural dimensions and appearance inspection - Insulation resistance at 20°C - Tensile performance - Low-temperature winding - Withstand voltage performance 4.2.3 Core Indicators 4.2.3.1 Rated voltage of 3.6/6 kV and below electric submersible pump cables: - Conductor DC resistance at 20°C - Thickness of the thinnest insulation layer - Rate of change in insulation tensile strength after aging - Rate of change in insulation elongation after aging - Maximum elongation under heat extension test load 4.2.3.2 Corrosion detection cables for oil and gas drilling and extraction equipment: - Conductor DC resistance at 20°C - Thickn
