Flexible corrugated polyamide conduits (PA 6), designed for optimum flexibility, high compression resistance and excellent response to impact; ideal requirements in all applications for protecting and insulating electrical installations. Excellent resistance to most chemical substances such as oils (max. Temp. +80°C), petrol, acids and solvents. Self-extinguishing, with low toxicity and low smoke density. Halogen, silicone and cadmium-free. Low fume emission in case of fire makes these conduits particularly suitable for applications in the railway sector and in all places where there is a greater risk of fire. Corrugated internal and external surfaces ensure an excellent sliding of the cables, significantly easier than with flexible PVC conduits.
