The wire trunking range HelaDuct covers a wide variety of widths (15 -150 mm) and heights (up to 100 mm).
All HelaDuct products feature a base perforation according to DIN EN 50085.
PVC wire trunking available
They are used in control panels, switching systems and especially electronic control systems.
HelaDuct HTWD-HF wire trunking are used in control panels and switching systems where there are high demands on personal or material safety in case of fire, such as in public transport, tunnels, data-processing centers or public buildings.
Main benefits:
The HelaDuct wire trunking range features the blue ducts HTWD-PWB which are used to identify intrinsically safe wiring, for instance in chemical plants or anywhere where there are explosive environments.
Keep your panel orderly and save time and costs with HelaDuct wire trunking retainers and other accessories.
The HelaDuct product range includes two different wire retainers:
1. HelaDuct HTWD-BWR base wire retainers are installed in the wiring duct cabling
2. HelaDuct HTWD-NFWR and HTWD-WFWR wire retainers can be installed in the wiring duct
HelaDuct HTWD-BWR wire trunking retainers are quick and easy to mount and hold wires firmly during wiring, especially where the ducts are installed vertically on in the ceiling.
They offer significantly higher secure and robust fixing than conventional solutions with adhesives because they are mechanically affixed to the duct.
Fixing the trunking retainers in the duct is simple. HTWD-BWR retainers are locked securely into place in the duct with light press and twist of a screwdriver.
Main benefits:
HTWD-NFWR and HTWD-WFWR wire trunking retainers are easily inserted onto fingers and hold wires securely into place when cover is removed.
Main benefits:
Fixing the retainers in the duct is simple. HTWD-NFWR and HTWD-WFWR retainers are simply clicked into place on a duct finger.
HelaDuct HTWD-CTH is used to anchor a cable tie securely to the base of a duct. The HTWD-TL is used to fix a HTWD-RB rail mounting block to duct in order to mount duct to DIN rails.

Wiring ducts – also known as wire ducts or wire trunking – are rectangular channels designed to protect, organize, and route electrical wires, cables, and hoses. Naming varies among industries and manufacturers. The term "wiring" is generally used for channels that are open on the sides and that are primarily used in installations areas where the wires are finally connected to their destination systems for example inside electrical enclosures.
Wiring ducts enable routing vertically, horizontally or upside down. In accordance with basic standards of electrical installation, routing will always be in parallel or orthogonally. Wiring ducts play a crucial role in managing and safeguarding wiring systems in panel building with high demands on personnel and material safety.
Installation ducts are closed channels intended to route cables over long distances. Wiring ducts have (sometimes expandable) openings and are optimized for the individual routing and final wiring process at the destination. Therefore a common application for wiring ducts is switch cabinets.
Besides protecting, managing, and organising cables, wiring ducts offer several other advantages:
The quality of cable channels can be assessed based on a range of hard and soft factors. Among the hard facts are standardized dimensions and perforations, ensuring consistent compatibility. Flame resistance and halogen-free properties are crucial for safety in case of fire. Soft factors like a smooth, burr-free surface help avoid injuries and cable damage. An effective fastening system and the electrical safety of the plastic are also important. The easy installation and secure attachment of the cover, flush with the bottom of the channel, as well as wire retainers at the same level, enhance user-friendliness.
Choosing the right wiring duct size depends on the number and diameter of cables you need to accommodate. Measure the total cable bundle size and length required and select a wiring duct that can comfortably hold your cables while leaving some room for future expansion and ventilation. Usually, wiring ducts can be easily cut to the right length with a backsaw (fine-toothed recommended, e.g., hacksaw).
For final distribution on certain levels within the cabinet it is advised to use small cable ducts to optimize space-usage. A good product for this is the tubular, wrap-based HelaDuct flex.
For a panel builder, it is important to be able to construct panels that are clear and flexible. It can therefore be a good idea to combine several types of cable protection and cable labelling. With our cable ducts, the quality-conscious panel builder can:
DIN wiring duct refers to the specified external dimensions of height and width. These dimensions are based on the DIN 43659 standard, which has since been withdrawn but is still widely used in the industry. DIN sizes include size increments like 20, 25, 75/2, 50, 75, 100, 125 for width and height.
Metric sizes are a different system than DIN. They include more height-width combinations. Both metric and DIN channels use metric – meter-based – units of measurement as opposed to imperial units of measurement.
DIN can also refer to the standardisation of the bottom perforation of the duct. The perforation is used when mounting the duct to the cabinet. The position of the oblong holes used to be specified in the DIN 43659 standard. The standardization is still present e.g., in the current standard DIN EN 50085-2-3 as an example. When looking for a standard perforation according to DIN, DIN EN 50085-2-3 should be used.
