Advantages：
MYJV (Non-Armored): 
Lightweight and flexible, suitable for fixed installation scenarios with no risk of mechanical damage.  
Lower cost, meeting high-voltage power distribution needs in underground environments without additional protection requirements.
MYJV22 (Steel Tape Armored):
Resistant to compression and impact, suitable for direct burial or tunnel installation in areas prone to external damage.  
Protects against rodent and insect bites, extending the service life of cables in mine tunnels.
MYJV32 (Fine Steel Wire Armored): 
High tensile strength, suitable for vertical shafts, slopes, and other installation environments with significant height differences.  
Resistant to torsional deformation, adapting to the movement or vibration of underground equipment.
Common Advantages:  
Flame-retardant, low-smoke, and halogen-free.  
Cross-linked polyethylene insulation resists partial discharge, ensuring high long-term operational reliability.  
Resistant to moisture and corrosion, adapting to high-humidity and acidic underground environments.

Application Scope:
Mainly used for fixed high-voltage power supply in underground coal mines (e.g., MYJV22/MYJV32), mobile high-voltage equipment (e.g., MTJV for coal shearers, roadheaders), underground substations, high-voltage distribution systems, and long-distance high-voltage transmission.

Special Notes:
MYJV22 is suitable for general crush-resistant environments; MYJV32 is suitable for vertical shafts or inclined roadways requiring tensile strength; MTJV uses flexible conductors and multi-layer shielding, suitable for frequent movement scenarios; all models pass coal mine flame retardancy and impact resistance tests.
