The Helavia DA 90/200/30 black is a cable gland made of polychloroprene rubber, manufactured by Ses-Sterling. It serves as a protective and guiding element for cables and lines when passing through wall or ceiling openings in electrical and technical installations. The gland is black in colour and is supplied in a pack of 100 pieces. Its use is particularly common in electrical installations, where secure and durable cable guidance is required to prevent mechanical damage and protect the insulation of the lines.

Cable glands are specially designed protective elements installed in openings of components such as walls, ceilings, or enclosures to safely guide cables or lines. The Helavia DA 90/200/30 is designed for a passage with an inner diameter of 90 mm, while the outer shape has a diameter of 200 mm and a length of 30 mm. These dimensions allow for a secure fit in standard installation scenarios, especially when laying multiple cables or larger cross-sections. The gland is typically installed in conjunction with cable protection conduits or directly into component openings.

Polychloroprene rubber is the material used, known for its high mechanical strength, weather resistance, and chemical resistance. It provides good protection against mechanical stresses, such as friction or pressure, and is resistant to UV radiation and many industrial chemicals. The material choice ensures a long service life of the gland, even under harsh conditions in indoor and outdoor environments. The black colour is standard and blends visually into most installation scenarios.

Protective function and cable guidance are the primary tasks of the gland. It prevents cables from being damaged during passage through openings, particularly by sharp edges or mechanical stress. The elastic structure of the polychloroprene rubber allows for a secure yet flexible fit around the cables, achieving a tight and stable guidance. The gland is not designed for power supply or data transmission, but is purely mechanical and protective in function.

The gland is typically manually inserted into the opening and holds securely in place due to its shape and elasticity. No additional fastening is required, as the design ensures reliable retention. Installation is tool-free and quick, speeding up the process in construction projects or maintenance work. The gland is not intended for dynamic movements or frequent repositioning, but for permanent, static fixation.

Compatibility is provided with standard installation scenarios, particularly in electrical and building technology. The gland is designed for use in wall and ceiling openings with a diameter of approximately 90 mm. It can be combined with various cable types, such as electrical wiring or data cables, as long as their diameter falls within the gland’s guiding capacity. Use in combination with other protective or guiding elements is possible, provided mechanical and geometric requirements are met.

The gland is available in a pack of 100 pieces, making it suitable for large projects or series installations. The weight per piece is 6.25 g, indicating a compact and lightweight design. The packaging weight of 0.625 kg corresponds to the total weight of the 100 pieces. The EAN number 3597470017340 serves for unique product identification in trade.

Applications include electrical installations in residential and commercial buildings, industrial facilities, and building technology. The gland is particularly suitable where mechanical protection for cables is required when passing through components. It is frequently used in conjunction with cable protection conduits, distribution boxes, or other installation elements to ensure proper and safe cable routing.

Operational advantages include easy installation, high mechanical stability, and long service life. The gland requires no additional fastening elements and can be installed quickly and without tools. The material quality ensures reliable protective performance throughout its entire service life, minimizing maintenance and replacement intervals. Standardized dimensions enable universal use in various installation scenarios.
