ABB offers Q‑Flex, a plastic, insulating, shockproof, self‑extinguishing duct. Made in compliance with UL 94 V2 Standard and resistant to permanent temperature of 80°C and peaks up to 110°C in compliance with IEC 216 standards. Ribs alternate and angle slightly inwards to make it easier to insert and extract cables. Suitable for connecting panels and doors with compass‑opening mechanisms and in general for applications where cabling is subject to bending and twisting.
