Product Description
TVVBG : Product Description and Specifications
Designated as Type TVVBG (Steel-Reinforced Flat Cable), this specification integrates dual galvanized steel strain relief members positioned laterally parallel to the cores. Engineered for high-rise vertical suspension, the reinforced design enables unsupported hanging lengths up to 80m at speeds of 4 m/s, preventing conductor elongation under tensile load.

Advantages
TVVBG : Benefits and Features
Integrated Steel Strain Relief Features dual galvanized steel wire ropes embedded within the sheath. Absorbs tensile stress to prevent copper conductor elongation (stretching) during rapid acceleration.
80m Suspension Height Reinforced construction allows for unsupported vertical suspension up to 80 meters, significantly exceeding the 35m limit of non-reinforced cables.
High-Speed Stability (4 m/s) Aerodynamic flat profile combined with high tensile strength enables stable operation at travel speeds up to 4 m/s without vibration or “whipping”.
Flat Anti-Torsion Design Parallel configuration prevents torsional twisting (corkscrewing) in the elevator shaft, ensuring smooth stacking in the cable trough.

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: Primary Application?
A: High-Rise Suspension.

Q: Speed & Length Limits?
A: 4 m/s & 80m.
Speed: Rated for moving speeds up to 4 m/s (High Speed).
Suspension: Supports a free-hanging length of up to 80 meters (unsupported).
Q:Structure: What does "G" stand for?
A: Steel Reinforcement (Gang).

Tests: Passed GB/T 18380 (Flame Retardant) and Static Torsion Tests (Anti-Twist).
Q : Core Identification?
A: GB/T 5023 Standard.
≤ 5 Cores: Color Coded (GB/T 5023.1).
