產品說明
TVVB-TV : Product Description and Specifications
指定為 TVVB-TV (Hybrid Elevator Cable), this specification integrates a precision 75Ω Coaxial Video Core within the standard flat control cable structure. Engineered for Analog HD CCTV systems, it provides a seamless ‘One-Cable’ solution for video and power transmission. Its balanced flat profile ensures smooth suspension and minimal vibration, protecting the coaxial dielectric from mechanical distortion during travel.

TVVB-TV: Benefits and Features
Hybrid 3-in-1 Design Combines Video (Coax), 力量, 和 Control in a single flat profile. Reduces installation time and saves valuable space in the elevator traveling cable trough.
75Ω Impedance Stability The integrated coaxial core is engineered to maintain a strict 75Ω characteristic impedance even under constant bending, ensuring crystal-clear images for CVI/TVI/AHD cameras.
Balanced Flat Structure The coaxial unit is centrally placed or symmetrically balanced with power cores to prevent the cable from twisting (corkscrewing) during vertical operation.
Interference Rejection 具有高密度的特性 copper braid shield around the coaxial core to block electromagnetic interference (EMI) from adjacent power lines in the shaft.

Q: What distinguishes the TVVBPG-TV model?
答: The “All-in-One” Flagship.
Triple-Layer Design: 整合 Video Core (TV) + 屏蔽 (P) + Steel Reinforcement (G).
定位: This is the most robust model in the series, specifically engineered for high-rise elevators operating in electrically noisy environments where standard cables would fail physically or electrically.
Q: Why is Steel Reinforcement necessary for Video?
答: Preserving Impedance Stability.
Physical: The embedded Galvanized Steel Ropes (YB/T 5196) absorb the entire tensile load.
Electrical Benefit: By preventing the cable from stretching, the steel ropes protect the Coaxial Core’s dielectric from deformation. This ensures the 75 輸入阻抗 remains constant, preventing video ghosting in tall shafts (Suspension > 45m).
Q: How does Shielding improve video quality?
答: VFD 噪音免疫。.
材質: 具有高密度的特性 鍍錫銅辮.
功能: Acts as a Faraday cage to block EMI/RFI generated by high-power VFD(逆變器) and motors.
結果: Ensures artifact-free, broadcast-quality video transmission even when running parallel to power cables.
Q:Is it suitable for Power & Data?
答: Composite 3-in-1 Solution.
是的: It combines Power/Control Cores (300/500V) with a dedicated 75Ω Coaxial Unit.
好處: A single cable installation manages the entire elevator security system (Camera Power + Video Signal + Mechanical Suspension).
Q:最小彎曲半徑?
答: 6 x 厚度。.
Rule: Radius ≥ 6 x 小軸 (電纜厚度)。.
設計: Despite the steel reinforcement and shielding, the flat profile maintains enough flexibility for standard elevator traveling loops.
Q:溫度範圍?
答: Cold & Durable.
範圍: -15°C至+70°C。.
護套: 用途 ST5 Compound to prevent cracking in cold shafts while maintaining the structural integrity needed to support the heavy copper/steel payload.
Q: Conductor Identification?
答: Standard Compliance.
≤5芯: 顏色編碼 (GB/T 5023.1)。.
> 5 核心: 黑色,白色編號 (GB/T 5023.1)。.
Q : Safety Standards?
答: Global Certification.
Manufacturing: 符合 IEC 60227-6 和 EN 50214.
安全: Flame retardant properties meet GB/T 18380 (IEC 60332-1) requirements.
