Scope

Scope: This document specifies the evaluation index system, evaluation methods, and grade classification for the "Leader" standard evaluation of mining cables. This document is applicable to the following products: - Soft cables for coal miners with a rated voltage of 1.9/3.3 kV and below - Shielded monitoring reinforced soft cables for coal miners with a rated voltage of 1.9/3.3 kV and below - Shielded soft cables for coal miners with a rated voltage of 1.9/3.3 kV and below - Mobile soft cables with a rated voltage of 0.66/1.14 kV and below - Mobile metal-shielded monitoring soft cables with a rated voltage of 8.7/10 kV and below - Mobile shielded soft cables with a rated voltage of 6/10 kV and below - Coal mine electric drill soft cables with a rated voltage of 0.3/0.5 kV - Mobile lightweight soft cables with a rated voltage of 0.3/0.5 kV Related organizations may refer to this document when formulating enterprise standard evaluation programs for "Leader" standards. Enterprises may also use it as a reference when developing their own enterprise standards. **Main Technical Content**: 4.2 Classification of Evaluation Indicators 4.2.1 The "Leader" standard evaluation of mining cables is divided into basic indicators, core indicators, and innovative indicators. 4.2.2 Basic indicators include: - Conductor DC resistance - Insulation resistance - Power frequency voltage performance - Insulation water absorption performance - Surface marking - Cable outer diameter - Conductor wire diameter - Insulation thickness - Sheath thickness - Single vertical flammability performance - Burning performance under load - Bunched burning performance 4.2.3 Core indicators include: - Transition resistance - Sheath aging tensile performance: tensile strength and elongation at break - MYPTJ cable partial discharge performance Grade classification: - Advanced level: equivalent to a 5-star level in the enterprise standard ranking
