Particularly wide webs and slots for larger cable diameters. Well suited for heavy cables thanks to the stable design of the duct walls. Smooth, burr-free edges protect users and cables. Burr-free removal of webs and wall segments thanks to predetermined breaking points. Simple and secure attachment of accessories using mounting points. Retaining brackets and other accessories do not protrude from the duct floor. The cover fits securely even under difficult conditions such as vertical installation and vibration. Covers flush on the sides for optimal use of space. The HTWD-PW wiring ducts can therefore also be installed with the cover, close together. Additional retaining lug from a height of 80 mm, which prevents the cables from slipping. Base perforation in accordance with DIN EN 50085. The HTWD-PW wiring duct is used in control cabinets and switchgear and is particularly suitable for cables with a larger cross-section.
