Elevator systems in high-rise buildings and industrial environments face unique challenges: extreme vertical tension, constant movement, and electrical interference from complex control systems. The TVVBPG Dual-Steel Reinforced Shielded Flat Cable is engineered specifically to solve these problems.
Manufactured by Shanghai Rousheng Electric Wire & Cable Co., Ltd.—specialists in high-flexibility and special cables with over 100 distinct varieties—this cable combines robust mechanical strength with superior signal integrity. Whether you are modernizing a passenger lift or outfitting a heavy-duty freight elevator, this cable ensures stable transmission and long service life.
Why Choose TVVBPG for Vertical Transportation?
1. Superior Anti-Interference (EMI Protection)
In modern elevators, data and video signals often run alongside power lines. Without proper shielding, this causes signal distortion and “ghosting” in video feeds.
- Solution: Our TVVBPG cable features a high-density tinned copper braid shield. This effectively blocks electromagnetic interference (EMI), ensuring clear communication between the elevator car and the control room.
2. Dual Steel Wire Reinforcement
Gravity is the enemy of long-distance suspension cables. Standard cables can stretch or snap under their own weight when used in shafts exceeding 80 meters.
- Solution: We integrate two galvanized steel wire ropes directly into the cable’s outer jacket. These bear the tensile load, preventing the copper conductors from stretching and ensuring the cable maintains its structural integrity even at suspension lengths over 80 meters.
3. Built for Constant Motion
Elevator cables undergo millions of bending cycles. Standard PVC cracks under this stress.
- Solution: We utilize a special modified PVC/NBR sheath that stays flexible even at low temperatures (-15°C). It is wear-resistant, oil-resistant, and engineered to withstand a small bending radius without fracturing.

Frequently Asked Questions (FAQ)
Q: What is the difference between TVVBP and TVVBPG?
A: The “G” stands for Steel Wire Reinforcement. TVVBP is a standard shielded flat cable suitable for lower heights. TVVBPG includes dual steel wires to support the cable’s weight, making it essential for suspension lengths exceeding 80 meters or high-speed applications.
Q: Can Shanghai Rousheng customize the core count for video or data integration?
A: Yes. As a manufacturer with R&D capabilities, we can integrate coaxial cables (for video), CAT5e/CAT6 (for data), and power cores into a single flat composite cable to suit your specific control system.
Q: Does the cable withstand cold environments?
A: Absolutely. Our standard sheath is rated for dynamic use down to -15°C. For extreme cold storage or outdoor environments, we can manufacture cables using specialized low-temperature compounds rated for -40°C.
Q: What is the typical lead time for international orders?
A: For standard specifications, production is efficient. We export to over 100 countries and can typically arrange shipment within 10-15 days depending on order volume.
Q: How do I ensure I order the right size?
A: Please provide the number of cores, the cross-section area (e.g., 24×0.75mm²), and the suspension length. Our engineering team can assist in calculating the necessary tensile strength and shielding requirements.
Q: Is the cable compliant with EU standards?
A: Yes, our cables are manufactured in compliance with major international standards, including CE and RoHS requirements, ensuring safety and environmental responsibility.
