The MYQ Cable is a type of flexible mining power cable designed for heavy-duty mobile equipment used in underground mines and industrial environments. The abbreviation “MYQ” stands for Mining (M), Flexible (Y), and Light-duty Power (Q), which reflects its key properties—flexibility, safety, and suitability for equipment requiring continuous movement and stable power supply.
Compared with ordinary electrical cables, the MYQ Cable is built to operate under extreme conditions such as moisture, mechanical stress, and frequent bending. It provides reliable energy transmission for mining machinery, portable tools, and tunnel lighting systems, ensuring stable performance and maximum operational safety.
Every MYQ Cable is carefully engineered to ensure both flexibility and durability. Its structure typically consists of multiple layers, each contributing to its outstanding performance in tough environments.
Conductor: High-conductivity stranded copper wires that offer maximum flexibility and low electrical resistance.
Insulation: Special-grade rubber insulation (EPR or natural rubber) designed for high dielectric strength and excellent heat resistance.
Filler: Non-hygroscopic material maintains the cable’s roundness and flexibility while minimizing internal stress.
Inner Sheath: A soft protective rubber layer that enhances insulation protection and mechanical integrity.
Outer Sheath: Made from reinforced rubber compound resistant to oil, flame, abrasion, and chemicals commonly found in mining environments.
Each layer of the MYQ Cable serves a critical function, ensuring that the cable performs reliably even during constant movement and exposure to rough handling.
The MYQ Cable stands out for its excellent combination of electrical and mechanical properties. The following are its most important characteristics:
Superior Flexibility: The finely stranded conductor and soft rubber sheath allow for smooth bending and continuous motion without fatigue or cracking.
High Mechanical Strength: It resists stretching, impact, and crushing forces, ensuring longer service life.
Flame Retardant and Oil Resistant: Designed to operate safely in environments where sparks, oil, or moisture are present.
Excellent Insulation Resistance: Maintains stable performance even in wet or high-humidity conditions.
Temperature and Weather Resistance: Suitable for both underground mines and outdoor environments, performing reliably under wide temperature variations.
These properties make the MYQ Cable ideal for applications where flexibility, durability, and safety are equally critical.
When selecting or specifying an MYQ Cable, it’s essential to understand its basic technical parameters.
Rated Voltage: 0.66/1.14 kV
Conductor Material: Tinned or bare stranded copper (Class 5 flexibility)
Insulation Material: EPR or natural rubber
Sheath Material: Chloroprene or equivalent oil/flame-resistant rubber compound
Operating Temperature Range: -35°C to +90°C
Minimum Bending Radius: Not less than 6 times the outer cable diameter
Standards: Compliant with GB/T 12972.5 or MT818 mining cable standards
Color of Outer Sheath: Typically black or yellow for easy visibility underground
These specifications ensure that the MYQ Cable delivers consistent electrical performance, mechanical protection, and long-term reliability in challenging industrial environments.
The MYQ Cable is widely used in various sectors that demand flexibility, strength, and consistent energy transmission. Typical applications include:
Underground Mining: Power supply for mobile or portable machinery such as drills, pumps, or lighting systems.
Tunneling Projects: Ideal for temporary electrical installations and equipment that require frequent relocation.
Construction and Quarrying: Suitable for heavy-duty portable tools and transport systems.
Industrial Manufacturing Plants: Used in conveyor systems, electric hoists, and reeling equipment.
Temporary Power Distribution: Perfect for construction sites or maintenance areas needing flexible and durable cable solutions.
No matter the environment, the MYQ Cable ensures continuous and safe power delivery, minimizing operational interruptions.
Choosing the right power cable for mining or industrial applications can significantly affect equipment performance and operational safety. The MYQ Cable offers several advantages that make it a preferred choice among professionals:
Enhanced Flexibility: Allows easy installation, reeling, and movement without damaging the conductor or insulation.
Extended Service Life: Engineered rubber materials resist wear and environmental degradation, reducing the need for replacements.
Safety and Reliability: Fire-resistant and oil-proof construction reduces the risk of electrical faults or fire hazards.
Stable Power Transmission: The low-resistance copper conductor ensures efficient energy delivery even under high current loads.
Easy Maintenance: Smooth surface and durable structure make inspection and handling simple.
By integrating these benefits, the MYQ Cable guarantees dependable performance and excellent value for mining and industrial users.
Although both MYQ Cable and MYP Cable are mining power cables, they serve slightly different purposes.
MYQ Cable: Designed for light to medium-duty mobile equipment, focusing on flexibility and lightness.
MYP Cable: Suitable for heavier-duty machinery or reeling systems that require higher voltage and thicker insulation.
MYQ Cable is typically smaller in diameter and more flexible, making it easier to install in narrow or curved spaces.
It is ideal for power tools, portable lighting, and smaller mobile equipment that demand frequent movement and easy handling.
Understanding the differences helps customers choose the right product for their specific operational needs.
To maximize performance and lifespan, the MYQ Cable must be installed and maintained correctly. Follow these essential practices:
Avoid over-bending or twisting during installation.
Use proper clamps and cable supports to prevent mechanical strain.
Inspect insulation and sheath integrity regularly.
Keep the cable away from sharp edges or high-heat sources.
Replace damaged sections immediately to maintain safety and performance.
Proper handling ensures that your MYQ Cable remains reliable throughout its service life.
A premium MYQ Cable is manufactured according to strict quality control and testing procedures. These include:
Conductor Resistance Test to confirm low electrical resistance.
Voltage Withstand Test to ensure insulation integrity.
Insulation Resistance Test to measure dielectric performance.
Flexibility and Bending Test for mechanical durability.
Flame and Oil Resistance Test for safety assurance.
Only cables that meet all these standards are suitable for mining and industrial applications where safety cannot be compromised.
Mining and heavy industry require cables that perform reliably under constant motion, pressure, and environmental challenges. The MYQ Cable is specifically engineered to meet these conditions. Its combination of high-quality copper conductors, durable rubber sheathing, and superior flexibility ensures long-term, trouble-free operation.
By selecting MYQ Cable, businesses benefit from:
Lower maintenance costs due to extended cable life.
Improved operational safety and efficiency.
Fewer equipment breakdowns caused by unstable power supply.
Compliance with national and international mining standards.
This makes the MYQ Cable a sound investment for mining contractors, industrial operators, and equipment manufacturers alike.
The performance of the MYQ Cable depends not only on its design but also on the manufacturer’s quality assurance. When selecting a supplier, consider the following factors:
Proven experience in producing certified mining cables.
Complete quality documentation and test reports.
Customization options for conductor size, length, or sheath material.
Reliable delivery schedules and professional technical support.
Working with a reputable manufacturer ensures you receive an MYQ Cable that meets your specifications and performs dependably in the field.
In modern mining and industrial operations, flexibility and reliability are essential for maintaining safety and productivity. The MYQ Cable delivers both. With its flexible copper conductor, durable rubber insulation, and high resistance to mechanical and environmental stress, it ensures continuous power transmission in the most demanding conditions.
Whether for underground mining, tunnel construction, or mobile power equipment, the MYQ Cable provides the dependable electrical connection you can trust.
