The Helavia DA 70/120/20 black is a cable gland made of polychloroprene rubber, manufactured by Ses-Sterling. It serves as a protective and guiding element for cables and wires when passing through components, such as wall or ceiling openings, ensuring a secure and tight connection. The gland is black in colour and is supplied in a pack of 100 pieces. Its typical applications include electrical installations, device mounting with cable entries, or industrial plant construction, where mechanical and electrical insulation as well as protection against environmental influences are required.

Cable glands are specially designed protective elements that shield cables during entry and exit through components from mechanical damage. The Helavia DA 70/120/20 is designed for this purpose, with the designation DA 70/120/20 indicating its technical dimensions: the inner diameter is 70 mm, the outer diameter is 120 mm, and the length of the gland is 20 mm. These dimensions allow for a precise fit in standard openings and provide sufficient space for multiple cables or wires. The gland adapts to the cables through its elastic structure, achieving a tight but not overly tight fit that prevents cables from shifting or slipping.

Polychloroprene rubber is the material used, known for its high chemical resistance, weather resistance, and mechanical strength. It is particularly suitable for use in indoor and outdoor environments, as it is resistant to UV radiation, moisture, and temperature fluctuations. The gland is therefore also suitable for applications in humid or industrial environments where high durability and reliability are required. The black colour is standard and blends visually into most installation scenarios without impairing functionality.

Applications include electrical installations in residential and commercial buildings, mounting of devices such as thermostats, light switches, or socket boxes, as well as industrial plants where cables are routed through walls, ceilings, or machine enclosures. The gland is often used in combination with other protective and mounting elements to ensure a complete and secure installation. Installation typically requires no additional tools, as the gland is elastic and can be pressed into the opening by hand.

Functions and features in detail include the elastic shape, which enables a tight fit around the cables, and the robust material structure, which guarantees a long service life. The gland is not designed for power supply or data transmission, but exclusively as a mechanical and protective termination. The packaging contains 100 pieces, which is sufficient for larger projects or series installations. The individual weight of 1.82 g per gland is technically relevant, especially for logistics and storage, but not directly critical for the user during operation.

Technology explained simply means that the gland encloses the cables through its elastic structure, providing mechanical protection. The polychloroprene rubber material ensures high resistance to external influences, making the gland suitable for a wide range of operating conditions. The dimensions of 70 mm inner diameter, 120 mm outer diameter, and 20 mm length are tailored to standard installation scenarios, allowing the gland to be used without additional modifications.

Compatibility and accessories refer to its use in combination with other installation elements, such as cable protection conduits, wall penetrations, or mounting components. The gland is not specific to any particular brand or product line, but can be universally used as long as the opening dimensions and cable diameter match.

Mounting and installation is carried out by simply inserting the gland into the designated opening. The elastic structure allows for a secure and tight fit without requiring additional tools or adhesives. The gland is positioned so that the cables pass through the inner side and the outer side seals the opening. Installation is quick and does not require special expertise.

Operational advantages include easy handling, high material durability, and universal usability. The gland provides lasting mechanical protection, prevents cables from slipping, and protects against external influences such as dust or moisture. The pack of 100 pieces enables efficient use in larger installations.
