In-depth Analysis of Industry Requirements: Rail transit constitutes a vital lifeline for public safety, imposing some of the most stringent standards for cables across all sectors. Cables must guarantee continued functionality under extreme conditions including fire, vibration, impact, humidity, and chemical corrosion. Core requirements encompass high safety, reliability, longevity, and environmental sustainability. Particularly crucial is fire safety, demanding cables that produce low smoke, are halogen-free and low-toxicity when burning, while maintaining circuit integrity for a specified duration within flames.
Henghui Cable's Core Solution: Henghui Cable fully complies with international and Chinese railway standards, providing complete vehicle wiring systems for rail transit. We employ halogen-free, low-smoke, flame-retardant materials to maximise passenger and staff safety during fires. Our products undergo rigorous testing for resistance to oil, fuel, coolants, and UV radiation, while withstanding prolonged vibration and impact. From rolling stock to fixed installations, we offer a complete product range meeting diverse fire-resistance ratings and providing moisture and mould protection.
Typical Application Examples:
① Tramway-specific cables: Henghui's YG-WDZ-YJE23 series cables are extensively deployed in tramway power supply systems. Serving as the core component linking power systems to tram operations, they facilitate electrical transmission, signal control, safety assurance, and stable system functioning throughout the entire process. It combines high conductivity, heat resistance, interference immunity, and environmental adaptability to ensure efficient and safe tram operation, providing a more reliable ‘lifeline’ for urban rail transit.
