Railway electrification cables represent specialized products meeting stringent safety and performance standards for mass transit systems. Weidong Cable's railway solutions include catenary wires, feeder cables, and signaling power cables complying with EN 45545 and NF F standards. A metro extension project in Shanghai utilized our 1500V DC traction power cables with fire performance ratings for underground sections. These cables feature low-halogen insulation reducing corrosive gas emission during tunnel fire scenarios. For high-speed rail applications, specially formulated jackets resist aerodynamic forces at operational speeds. The company's testing includes extended flame spread tests simulating tunnel fire conditions per EN 50266. Clients in mountainous regions specify our cables with enhanced UV resistance for elevated sections. We provide system compatibility analysis for interfaces between different railway electrification systems. Technical documentation includes comparative analysis of global railway standards like IRIS and RICS. For interoperability projects, please share specific rolling stock specifications and power supply characteristics. Manufacturing processes include controlled oxygen-free copper drawing ensuring maximum conductivity. Research collaborations focus on developing composite overhead lines reducing pantograph wear. Case studies from cross-border railway projects demonstrate our cables' performance under varying climatic conditions. Clients in urban transit systems require reduced electromagnetic interference for parallel communication cables. Installation engineering includes specialized tensioning equipment for overhead catenary systems. For depot applications, customized marking systems facilitate maintenance and troubleshooting. Logistics planning accounts for limited access windows during railway operation hours. Training programs include safety protocols for working near energized railway systems. Digital tools include catenary design software integration capabilities.

Common problem

What types of power cables does Weidong Cable (as a Jinlongyu agent) offer?

Weidong Cable, a first-tier agent of Jinlongyu Group, offers various power cables, including flame-retardant power cables (e.g., ZC-BV, ZC-BVR), low-smoke halogen-free power cables (e.g., WDZ series), fire-resistant power cables, cross-linked polyethylene insulated power cables (rated voltage 1kV-500kV), and armoured power cables (e.g., YJY23, YJLY33). These cover needs for high safety, high performance, and different scenarios.
Key materials are high-quality: conductors use copper (GB/T 3952) from Jiangxi Copper; insulation uses cross-linked polyethylene (from Shenzhen Liaohua) and PVC; sheaths use low-smoke halogen-free materials (from Kingfa Science & Technology); flame-retardant layers use mica tape (from Jiangsu Ruisi), enhancing performance and safety.
These cables have excellent flame-retardant (e.g., B1 class, ZC series) and fire-resistant properties. They meet GB 31247-2014 (combustion performance), resist fire spread, emit low smoke/halogen, and maintain power transmission in fires, suitable for fire-sensitive areas.
Yes. Weidong has an extensive sales network (covering Pearl River Delta, Sichuan, etc.) and has supplied Jinlongyu power cables to large projects like Shenzhen Shunfeng Headquarters Building and Cancer Hospital Reconstruction, meeting large-scale engineering’s high-demand and high-quality requirements.
