TRVV Reliable electrical performance Drag Chain Cable

Excellent Bending Fatigue Resistance: 
Designed specifically for the vertical reciprocating motion of elevators, it can withstand millions of bending cycles within elevator shafts.
Reliable Electrical Performance: 
Power, control, signal, and communication cores are integrated into a single cable, ensuring organized wiring and minimizing interference.
Environmental Adaptability:  
The PVC sheath provides basic resistance to oil, moisture, and mildew, making it suitable for elevator shaft environments in buildings.
Application Scope:Used as a traveling cable for elevators, lifts, or other vertical lifting equipment, connecting the car to fixed points in the shaft to transmit power, control commands, signals, communications, and video.

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, offering excellent electrical performance and flexibility.  
Core Structure: Multi-core integration with flexible configurations, such as:  
• Power cores (3-phase + ground)  
• Control cores (multiple cores, often twisted pairs)  
• Communication cores (e.g., shielded twisted pairs)  
• Video cores (e.g., coaxial cables)  
Tensile Element:** Central or integrated aramid yarn, fiber rope, or galvanized steel wire rope. This is a critical structural component of elevator cables, designed to withstand the weight of the elevator car and partial loads.  
Filling: Non-hygroscopic filling material to maintain cable roundness.  
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).
