Extreme flexibility and high tensile strength:
The combination of ultra-flexible conductors and integrated tensile elements meets the requirements for high-speed reciprocating motion of elevators.  
Signal integrity guarantee:
Adding overall shielding on the basis of twisted pair or individual shielding forms multiple layers of protection, which is particularly suitable for transmitting bus signals (such as CAN, Ethernet) and video signals in modern machine-room-less elevators, high-speed elevators, and intelligent elevators.  
Reliable mechanical and environmental durability: 
Designed specifically for the vertical reciprocating bending environment of elevator shafts, it has a long bending life. The PVC sheath provides basic environmental protection.  
Application scope: Used in elevators, lifts, and vertical lifting systems where there is a risk of electromagnetic interference or high requirements for signal transmission quality, serving as traveling cables to transmit mixed power, control, data, and video signals.

Conductor: Class 6 annealed copper conductor (multi-strand ultra-fine copper wires), extremely flexible. Cross-sectional range: 0.75 mm² to 2.5 mm² (signal/control), 4 mm² to 35 mm² (power).  
Insulation: Special flexible PVC, color-coded.  
Core Structure: Multi-core integration with flexible configurations, such as:  
• Power cores (3-phase + ground)  
• Control/signal cores (multiple cores, often twisted pairs to reduce internal crosstalk)  
• Communication/bus cores (e.g., CAN bus, Ethernet pairs)  
• Video cores (e.g., coaxial cables)  
Tensile Element: Central or integrated aramid yarn, fiber rope, or galvanized steel wire rope to withstand mechanical tension.  
Filling: Non-hygroscopic filling material to maintain cable roundness.  
Shielding Structure (Core Feature): Overall shielding: Typically uses tinned copper braided mesh or aluminum-plastic composite tape + drain wire, with coverage ≥80%, enclosing all cable cores inside the sheath. Some models may include individual shielding for critical pairs (e.g., communication pairs).  
Sheath: High-strength, abrasion-resistant, and bend-resistant PVC, typically black or gray, and may feature low-smoke zero-halogen (LSZH) properties.  
Rated Voltage:300/500V or 450/750V.  
Long-term Operating Temperature: -15°C to +70°C (for mobile installation).  
Minimum Bending Radius: Mobile installation: 10 × D (where D is the cable outer diameter).  
Suspension Height: Designed based on the tensile element strength, typically supporting lifting heights of 80 meters to 200 meters.  
Flame Retardant Rating: Complies with GB/T 18380.1 (or IEC 60332-1).  
Shielding Effectiveness: Provides a certain level of electromagnetic interference (EMI) resistance, preventing external interference from penetrating or internal signals from radiating.
