Braided sleeving made of mono filament polyamide PA6.6, provide excellent resistance to abrasion, chemicals, fuels, liquid and mould. The high filling density (cov. >85%) and the strong yarn (0,25mm), allow its application in heavy uses. Self-extinguishing and no toxicity in case of fire make them particularly suitable in the railway sector and in all places with a greater risk of fire. Extreme ease of cables sliding and fitting; expanding the mesh it is possible to release one or more cables at any point of the wiring. The inclination of the frame may vary consequently to the diameter of the braid.
