MYP Cable Shielded Flexible Rubber Mining Power Cable

MYP: Coal‑mine movable shielded rubber‑sheathed flexible cable

Model Explanation

• M: For coal mine application (mining series, MA coal‑safety certification is required for underground installation)
• Y: Movable rubber‑insulated & rubber‑sheathed flexible cable, fine‑stranded copper conductor, resistant to dragging and repeated bending
• P: Individual semi‑conductive shielding (non‑metallic shield, each power core is equipped with shielding layer)

Applicable Standard

MT 818.5‑2011

Common Voltage Ratings

1. MYP‑0.38/0.66 kV
2. MYP‑0.66/1.14 kV (most widely‑used for underground coal mines)

Construction

• Conductor: Fine‑stranded class‑5 flexible copper, flexible & bending‑resistant
• Insulation: EPR (Ethylene‑Propylene Rubber)
• Shielding: Semi‑conductive shield over each insulated core
• Earth core: With semi‑conductive layer for fast leakage‑current discharge
• Outer sheath: Flame‑retardant rubber, impact‑resistant, wear‑resistant, anti‑static, non‑propagating‑flame

Application

For underground coal‑mine movable equipment such as roadheaders, belt conveyors driven by frequency converters and inverter‑fed machinery. Suitable for variable‑frequency loads, suppresses electromagnetic interference and triggers earth‑leakage protection upon fault conditions.

✅ Compare with MY cable: MY has no individual core shielding and is only for general power‑frequency equipment. MYP shall be selected for variable‑frequency applications.

Typical Specification Format

MYP‑0.66/1.14 kV 3×70+1×25 3 power cores + 1 earth core, common 3+1 configuration for mining cables.

Key Technical Parameters

• Max long‑term conductor operating temperature: ≤70 °C
• Minimum bending radius: 6 × overall cable diameter
