The Durchführungstüllen DA 60/90/20 from Ses-Sterling belong to the Helavia product series and are designed as moulded parts made of polychloroprene rubber. They are used for the secure and tight guidance of cables or lines through drill holes in enclosures, control panels or other components. The sleeves are finished in black colour and are particularly suitable for use in electrical installation, industrial automation, and in systems where mechanical and electrical insulation of the penetrations is required. The designation DA 60/90/20 refers to the technical dimensions: an inner diameter of 60 mm, an outer diameter of 90 mm, and a length of 20 mm. These dimensions allow for a precise fit in drill holes with a diameter of approximately 60 mm, with the sleeves ensuring a secure seal due to their elastic structure.

Applications

The Durchführungstüllen are used in the electrical and installation industry, where cables must be routed continuously through enclosures or walls. They are particularly suitable for use in enclosures, control systems, machine construction, and in building technology. The use of polychloroprene rubber ensures high mechanical strength, resistance to ageing and chemical influences, as well as good elasticity, enabling a tight seal even under varying temperature and load conditions. The sleeves are intended for indoor use, although the material properties also allow limited outdoor use under mild conditions.

Functions and Features in Detail

The Durchführungstüllen DA 60/90/20 are designed as cable glands, meaning that they create a self-sealing connection through their shape and elasticity as soon as a cable or line is pulled through the opening. The elastic structure of the polychloroprene rubber ensures that the sleeves adapt to the shape of the cable being routed and provide both mechanical and electrical insulation. The sleeves are not designed for use with multiple cables, but for guiding single lines. The black colour is standard and corresponds to the usual colour concept for electrical components in industry.

Technology Explained Simply

The Durchführungstüllen are made of an elastic material that wraps around the cable during installation, creating a tight connection. Polychloroprene rubber is a synthetic rubber that is resistant to UV radiation, ozone, and mechanical stress. The sleeves are not self-cutting and must be inserted into a suitable drill hole. The dimensions of 60 mm inner diameter, 90 mm outer diameter, and 20 mm length are chosen to fit precisely into standard drill holes with a diameter of 60 mm. The elastic expansion of the material ensures secure anchoring and prevents the sleeves from falling out of the hole.

Compatibility and Accessories

The Durchführungstüllen DA 60/90/20 are compatible with drill holes of 60 mm diameter and are suitable for guiding single cables or lines. They are typically used in conjunction with control panels, enclosures, or machine housings. There are no specific accessories that must be combined directly with this item. The sleeves are to be understood as individual components, inserted into the drill hole and fitted with the cable. Installation requires no additional tools or mounting aids.

Installation and Mounting

Mounting of the Durchführungstüllen is done by simply inserting them into a drill hole with a diameter of 60 mm. The sleeves are elastic and automatically adapt to the hole. After insertion, the cable is pulled through the opening, causing the sleeves to wrap around the cable and create a tight connection. Mounting requires no additional tools or adhesives. The sleeves are designed for single-use installation and should not be reused, as their elasticity diminishes with repeated loading.

Operational Advantages

The Durchführungstüllen DA 60/90/20 provide reliable mechanical and electrical insulation for cable penetrations. The use of polychloroprene rubber ensures long service life and resistance to environmental influences. The sleeves are easy to install and require no additional tools. The black colour matches standard colour schemes in electrical installations. The sleeves are available in a pack of 100 pieces, making them suitable for larger projects or series installations.
