Scope

Scope: This document specifies the evaluation index system, evaluation methods, and grade classification for the "Leader" standard evaluation of mining cables. This document applies to enterprise standard evaluations of soft cables for coal mining machines with a rated voltage of 1.9/3.3 kV and below; shielded monitoring reinforced soft cables for coal mining machines with a rated voltage of 1.9/3.3 kV and below; shielded soft cables for coal mining machines 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; coal mine electric drill soft cables with a rated voltage of 0.3/0.5 kV; and mobile lightweight soft cables with a rated voltage of 0.3/0.5 kV. Relevant institutions can refer to this document when formulating "Leader" evaluation schemes for enterprise standards, and enterprises can 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 indicators for mining cables are 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 single wire diameter, insulation thickness, sheath thickness, single vertical flammability performance, combustion performance under load conditions, and bundle combustion performance. 4.2.3 Core indicators include transition resistance and sheath aging pre-tension performance: tensile strength and elongation at break, and MYPTJ cable partial discharge performance. These indicators are divided into three levels: advanced level, equivalent to a 5-star level in the enterprise standard rank
