Armored High-Density Communication Cable HYAP22-30×2×0.5 Technical Analysis
I. Model Definition and Structure
HYAP22‌：
H: Intra-city Communication Cables (for Fixed Installation)
Solid polyolefin insulation (high stability in high-frequency signal transmission)
Aluminum-plastic composite tape with moisture-proof layer (dual protection against moisture and corrosion)
Copper wire braided shield layer (coverage ≥, anti-electromagnetic interference)
22: Double steel belt armored + polyethylene outer sheath (compressive strength ≥ 50 kN/m²).
30×2×0.5‌：
30 pairs: Twisted pair count (supports parallel transmission of multiple signals).
2×0.5: Each set contains 2 conductors (single conductor cross-sectional area 0.5mm², copper core diameter approx. 0.8mm).

Section 3: Application Scenarios
Mine Communication System: Suitable for explosion-proof and monitoring signal transmission in coal mine shafts (must comply with MT 386 flame-retardant standard).
Industrial Control Networks: Supports RS485/CAN protocols for data interaction between PLCs and devices.
Long-distance Transmission: Direct burial installation with IP67 protection level, resistant to mechanical damage.
Section 4: Certification and Laying Requirements
Mandatory Certification: Coal Safety Certification (MA Mark), MT 386 Flame Retardant Certification
Laying Standards: Direct burial depth ≥ 1.2m,牵引 tension ≤ 80% short-term tensile strength (≤1500N).
