Product Description
TVVBPG: Product Description and Specifications
Designated as Type TVVBPG (Shielded & Reinforced), this premium specification integrates Dual Galvanized Steel Strain Relief Members with a High-Density Tinned Copper Braid Shield. Engineered for mid-to-high-rise installations, it simultaneously prevents conductor elongation under vertical load and ensures signal integrity in EMI-critical environments (e.g., shafts with heavy VFD noise).

Advantages
TVVBPG : Benefits and Features
Reinforced Suspension (YB/T 5196) Integrated Dual Galvanized Steel Ropes (compliant with YB/T 5196) absorb tensile loads, allowing for unsupported free-hanging lengths up to 80m without conductor elongation.
EMC High-Density Shielding Features a Tinned Copper Braid (>85% optical coverage) to block EMI from VFDs (Inverters). Ensures signal integrity for CCTV and data in electrically noisy shafts.
Cold & Flame Resistant Specialized PVC/ST5 compound remains flexible at -15°C (Cold Impact Test passed) and meets IEC 60332-1 / GB/T 18380 flame retardant standards.
High Flex Life Class 5 fine stranded copper combined with a flat anti-torsion profile withstands constant bending cycles and prevents “corkscrewing” in high-speed applications.

Q: Difference between TVVBPG and Standard TVVB?
A: The Ultimate Upgrade.
TVVB: Standard unshielded, no reinforcement.
TVVBPG: Adds “P” (Shielding) and “G” (Steel Reinforcement).
Benefit: It combines the tensile strength of steel ropes (for high-rise) with the EMC protection of copper braiding (for anti-interference). The “All-in-One” solution for complex elevators.
Q: Speed & Suspension Limits?
A: High Performance Specs.
Speed: Rated for high-speed lifts up to 4 m/s.
Suspension: Integrated steel ropes allow for an unsupported free-hanging length of up to 80 meters.
Q: Why is Shielding Critical?
A: VFD Noise Immunity.
Material: Tinned Copper Braid (>85% coverage).
Function: Blocks Electromagnetic Interference (EMI) from VFDs (Inverters). Crucial for ensuring artifact-free CCTV images and error-free data transmission in electrically noisy shafts.
Q:International Standards?
A: Triple Compliance.
Standards: GB/T 5023.6, IEC 60227-6, and EN 50214.
Safety: Meets global safety requirements for lift and hoistway installations.
Q: Operating Temperature?
A: Cold Environment Ready.
Range: -15°C to +70°C.
Tech: Uses PVC/ST5 (Cold-Resistant Compound) to maintain flexibility and prevent cracking in unheated shafts (Cold Impact Test passed at -15°C).
Q: Installation Bending Radius?
A: 6 x Thickness.
Rule: Minimum bending radius ≥ 6 x Cable Thickness (Minor Axis).
Advice: Ensure the cable creates a natural loop. Do not force sharp bends, as this may damage the internal shielding braid.
Q: Core Identification?
A: GB/T 5023 Standard.
≤ 5 Cores: Color Coded (GB/T 5023.1).
> 5 Cores: Black with White Numbering + Green/Yellow Ground (GB/T 5023.1).
Q : Non-Elevator Applications?
A: Industrial Suspension.
Scope: Ideal for Gantry Cranes and Festoon Systems (Trailing) where high tensile strength is needed.
Restriction: Not recommended for Reeling Drums (due to flat profile limitations). Suitable for linear trailing motion only.
