Features
MYQ as a light-duty Mining Cable with Flexible Rubber，the biggest difference compared to the MY cable lies in the weight. MY cable is Medium/Heavy-duty. Used for large mobile machines (loaders, conveyors).
Technical Comparison: MYQ /Light-duty Mining Cable vs. MY Mining Cables
| Feature | MYQ (Light-duty Mining Cable) | MY (Standard/Heavy-duty Cable) |
|---|---|---|
| Full Name | Light-duty Mobile Mining Rubber Cable | Standard Mobile Mining Rubber Trailing Cable |
| Rated Voltage | 0.3/0.5kV | 0.38/0.66kV up to 1.14kV |
| Structure | Thinner rubber sheath, flexible & lightweight | Thick heavy-duty rubber sheath, highly wear-resistant |
| Mechanical Strength | Basic tear and bending resistance | Excellent resistance to crushing, impact & dragging |
| Cross-section Range | Smaller cross-sections (usually 0.75mm² to 4mm²) | Larger cross-sections (up to 95mm² or higher) |
| Portability | Highly portable, easy for frequent moving | Heavy, intended for fixed dragging or reel machinery |
| Main Application | Handheld electric drills, temporary lighting, portable tools | Underground coal cutters, conveyers, mobile substations |
Lightweight & Flexible: Small diameter and light weight for easy handheld operation.
Flame Retardant: Complies with strict underground fire safety standards.
Oil & Moisture Resistant: The rubber sheath handles the damp, oily conditions of mine tunnels.
Mechanical Durability: Despite being “light-duty,” it is built to resist scuffing and impact.
High Conductivity: Pure multi-strand copper ensures stable power and signal.
Application
Mine Lighting: Connecting portable or fixed lighting systems in tunnels.
Signal Systems: Wiring for underground communication and alarm systems.

FAQ
1. What is the explicit technical distinction between MYQ and standard MY mining cables?
Mechanical Weight & Portability Matrix:
The foundational choice maps strictly out to mechanical loading and deployment mobility. Our MYQ series is officially designated as a light-duty mobile mining wire rated at 0.3/0.5 kV, engineered with a thinner, optimized rubber matrix to ensure lightweight handling and high flexibility. Conversely, standard MY cables function as medium/heavy-duty trailing lines rated up to 1.14 kV, layered with an ultra-thick, heavy-duty rubber jacket designed specifically to withstand immense dragging stress from large underground loaders and conveyors.
2. Why is a Class 5 flexible stranded conductor structure mandatory for MYQ mining wires?
Dynamic Pliability & Conductor Fatigue Resistance:
Handheld electric drills, temporary tunnel lighting clusters, and portable maintenance gear subject cables to relentless twisting and acute bending angles inside tight mine shafts. Our MYQ mining flexible cord resolves internal metal fatigue by bundling 99.99% pure Oxygen-Free Copper (OFC) into high-strand Class 5 fine configurations. This architectural layout lowers the active bending radius and prevents wire snapping under aggressive daily manual manipulation.
3. How does the rubber compounding of MYQ safeguard underground circuits from water and oil?
Advanced Polymer Sealing & Soil Immunity:
Underground coal seams and rock tunnels are highly prone to persistent water seepage, damp mud, and chemical grease emitted by drilling machinery. Our light-duty mining cable utilizes a specially formulated, moisture-impermeable rubber jacket. This dense elastic compound acts as a flawless seal that resists localized oil splash, acid-alkali water runoff, and ozone cracking, maintaining dry and stable dielectric insulation for decades.
4. Does the ZHONGYI MYQ cable satisfy strict underground fire safety and flame-retardant parameters?
Self-Extinguishing & Anti-Explosion Safety:
Absolutely. In enclosed, high-risk mining atmospheres, fire prevention is a critical engineering benchmark. The outer rubber protective sheath of our MYQ series is chemically embedded with high-grade flame retardants, fully satisfying international IEC 60332-1 evaluation parameters. In an emergency hazard, the wire will not sustain combustion, is inherently self-extinguishing within seconds, and prevents horizontal fire propagation along cable trays.
5. What wholesale core configurations and project packaging logistics do you guarantee for bulk orders?
Rigorous B2B Supply Scale & Drum Security:
As an established direct factory cable supplier, we manufacture MYQ mining cables in multi-core clusters spanning 2 to 8 cores, with standard cross-sections tailored for portable utility tools. To shield the flexible, supple rubber jacket from mechanical tearing or structural crushing during international ocean sea freight transit, bulk wholesale orders are wound securely on heavy-duty treated wooden reels or reinforced drums, backed by complete Type Test Reports.
