Advantages
TVVBQG: Benefits and Features
Enhanced Signal Transmission: The integrated G50/125 multimode optical fibers and Class 5 twisted pairs provide superior stability for audio, video, and large-capacity data signals compared to traditional coaxial cables.
Anti-Interference: Designed with strong anti-electromagnetic interference (EMI) properties, ensuring clear signal quality in complex elevator shafts.
Optimized Structure: The flat composite design effectively improves the bending radius and reduces the cable’s self-weight.
Eco-Friendly: The optical unit utilizes non-metallic conductors, making the internal communication component more environmentally friendly.

Production Processes Of Elevator Cable
Our production relies on state-of-the-art manufacturing equipment to ensure exceptional flex-life and dynamic performance. The process integrates precision fine copper stranding with advanced flexible compound extrusion for maximum bendability. During the critical cabling stage, we implement specialized anti-twist core arrangement and steel-member integration for high-rise applications. Throughout production, strict quality controls—including online spark testing and continuous tension monitoring—are applied to every meter. This rigorous workflow guarantees our traveling cables meet stringent EN, IEC, and GB standards for safe vertical transport.
Packing For Shipment
To meet various transportation needs, there are many methods of packaging that can be used.
Have more questions?
Q: What does the model code "TVVBQG" indicate?
A: Hybrid Composite Structure.
TVVB: Flat Elevator Cable (PVC/PVC).
Q: Optical Fiber Unit (Integrated Data/Video transmission).
G: Steel Wire Reinforcement (Galvanized Strain Relief).
Definition: A high-end composite cable combining Power + Control + Optical Fiber + Steel Strength Members.
Q: Advantage: TVVBQG (Fiber) vs. Coaxial Cable?
A: Zero Interference & High Bandwidth.
EMI Immunity: Unlike coaxial cables, the optical fiber core is immune to electromagnetic interference from VFDs and motors, ensuring crystal-clear video.
Capacity: Offers significantly higher bandwidth for HD/4K CCTV and multimedia displays over long vertical distances without signal attenuation.
Q:Optical Fiber Specifications?
A: Multimode G50/125.
Fiber: Contains 2 cores of G50/125 Multimode Fiber (Gradient Index).
Auxiliary: Combined with 2 groups of Twisted Pairs (0.2mm^2) for data signals.
Result: A complete communication unit optimized for elevator internal networks.
Q:Why include Steel Wire Ropes?
A: Tensile Stability (80m+).
Components: Dual Galvanized Steel Messengers placed laterally.
Function: They bear the mechanical tensile load, preventing stress on the fragile optical fibers and copper cores during high-speed vertical travel.
Q: Core Configuration & Balance?
A: Symmetrical Layout.
Structure: Features 12 Control Cores ($0.75\text{mm}^2$) arranged in a split configuration (6 Left + Optical Unit + 6 Right).
Benefit: This perfect symmetry ensures the cable hangs straight without twisting (corkscrewing) in the shaft.
Q: Rated Voltage?
A: 300/500V.
Suitable for standard elevator control circuits (Control Cores) while the optical unit handles low-voltage data transmission.
Q:Flat Structure Benefits?
A: Stacking & Flex Life.
Radius: Allows for a smaller bending radius compared to round hybrid cables.
Storage: Stacks neatly in the cable trough, maximizing space efficiency in narrow hoistways.
Q : Video Monitoring Capabilities?
A: Designed for CCTV.
Yes: Specifically engineered for elevator security systems.
Performance: The integrated fiber unit transmits lossless video signals (no noise/snow) even in electrically noisy high-rise environments.
