High-Temperature Silicon Rubber insulated Power Cables having special Fire Performance for Railway Rolling Stock/Traction/Metro (EN 50382-1 and EN 50382-2)

These railway cables deliver superior performance in high-temperature environments, offering excellent flexibility and mechanical strength. Engineered for safe and efficient power transmission in traction systems, metro trains and rolling stock operating under extreme thermal and environmental conditions.

Application

Designed for railway rolling stock applications requiring superior fire performance and thermal endurance. Halogen-free with low smoke, toxicity and corrosivity. Ideal for power distribution in locomotives, metros, EMUs and MEMUs, they are well-suited for high-stress areas like traction converters, rooftop and under frame wiring and control systems.

Advantages

Engineered with advanced cross-linked silicone rubber compounds, superior mechanical durability-demonstrating high resistance to abrasion, tensile stress and cut-through damage. Outstanding chemical resistance ensures reliable performance in environments exposed to oils, fuels, acids and alkalis.

Designed for flexibility and ease of handling, these cables simplify installation and stripping processes, meeting the rigorous operational demands of modern railway systems
