HYAT43: Copper-core foam polyolefin insulated, filled moisture barrier layer, polyethylene sheathed, single coarse steel wire armored polyethylene sheathed local communication cable

HYAT43 Cable Advantages  
Ultra-High Tensile Strength Structure: Single thick steel wire armor provides a breaking force of ≥30 kN, enduring continuous mechanical loads under extreme weather conditions such as strong winds and ice loads.  
Heavy-Duty Dynamic Protection System: Thick steel wire armor combined with a filled moisture barrier ensures long-term reliability in high-risk scenarios such as river-crossing cables and canyon overhead lines.  
Ultimate Defense Against Geological Disasters: Thick steel wire armor can withstand geological hazards like landslides and rockfall impacts, making it suitable for complex geographical environments such as seismic zones and mountainous areas.  
Corrosion-Resistant High-Frequency Transmission: Dual anti-corrosion protection from galvanized thick steel wire and polyethylene sheathing, along with a filled moisture barrier blocking moisture erosion, ensures high-frequency signal quality in corrosive environments.  
Specialized for Long-Span Installation: Supports overhead installation with spans exceeding 500 meters, meeting the needs of long-distance communication trunk line construction in areas with significant terrain variations and difficult tower erection.  

Product Selling Points
