The Helavia DA 75/120/30 black is a gland sleeve made of polychloroprene rubber, designed for use in electrical and installation technology. The manufacturer is Ses-Sterling, and the product is distributed under the manufacturer's number 02520092010. This sleeve serves as a protective and guiding element for cables and lines when passing through components such as wall or ceiling openings, particularly in areas where mechanical and electrical insulation as well as secure cable management are required. The sleeve is black, making it suitable for use in industrial and commercial environments where a discreet yet robust design is required.

Gland sleeves are specially designed protective elements that shield cables from mechanical damage, such as friction or pressure. The Helavia DA 75/120/30 is designed for a passage diameter of 75 mm, with the sleeve itself having an inner diameter of 120 mm. The length of the sleeve is 30 mm, providing sufficient insertion depth into the component opening to ensure secure and tight guidance. The material, polychloroprene rubber (PCP), offers high mechanical strength, weather resistance, and good electrical insulation properties, making the sleeve suitable for use in both indoor and outdoor environments.

Functions and equipment in detail

The sleeve is designed to guide cables and lines safely and without damage through components. The shape ensures even distribution of pressure forces, preventing the cable from being compressed or flattened. The material surface is smooth, facilitating cable insertion and minimizing friction. The black color is not only aesthetically neutral but also resistant to UV radiation and other environmental influences, extending the sleeve's service life.

Technology explained simply

Polychloroprene rubber (PCP) is a synthetic elastomer known for its high resistance to oil, chemicals, and mechanical stress. It is flexible yet resistant to cracking and aging. The sleeve is offered in a standard size of 75/120/30 mm, where the numbers represent the outer passage diameter, inner diameter, and length respectively. These dimensions are designed for typical installation scenarios in electrical and building technology. The sleeve is supplied in a pack of 100 pieces, making it suitable for large projects and series installations.

Compatibility and accessories

The Helavia DA 75/120/30 is designed for use with cables and lines having a diameter of up to 75 mm. The sleeve is used in components with an opening of at least 120 mm in diameter to ensure a secure and tight fit. It is part of the HELAVIA product range from Ses-Sterling, which offers various sizes and variants for different applications. The sleeve is not specifically designed for any particular cable type but is suitable for a wide range of cable types, provided the dimensions and mechanical requirements match.

Installation and mounting

Installation is carried out by simply inserting the sleeve into the designated opening in the component. The sleeve is positioned so that it extends at least 30 mm into the component to ensure stable and secure guidance. Subsequently, the cables are pulled through the sleeve. The elastic properties of the material allow the sleeve to easily adapt to the cable's shape, providing a tight yet non-damaging fit. No additional tools or mounting aids are required.

Advantages in operation

The sleeve provides reliable mechanical protection for cables and lines, prevents friction damage, and ensures proper guidance. The material quality ensures a long service life and resistance to environmental influences. The standardization of dimensions simplifies planning and execution of installations, as the sleeve can be reused in various projects. The pack of 100 pieces enables efficient storage and use in larger installations.
