Suitable for subway, high-speed train traction, and signal cables, with much higher smoke density and toxicity indicators than general materials. Resistant to oil stains, acids and alkali, cold and hot alternation, and strong wear and extrusion resistance. Wide temperature range stability, resistance to tunnel moisture corrosion, and no metal corrosion smoke, ensuring the safety of escape in closed tunnels and carriages, and meeting the special fire prevention standards for rail transit.
