The Helavia DA 130/170/20 black is a cable gland from the HELAVIA form parts product group, manufactured from polychloroprene rubber. It serves as a protective and guiding element for cables and lines when passing through components, such as wall or ceiling openings, and is used in the field of electrical installation. The gland is black and enables secure, mechanically robust, and simultaneously elastic cable guidance, while also providing a certain level of protection against mechanical damage.

Cable glands are specifically designed for installation in building components where cables or lines must be routed through openings. The designation DA 130/170/20 refers to the specific dimensions: an outer diameter of 130 mm, an inner diameter of 170 mm, and a length of 20 mm. These dimensions allow compatibility with standard cable glands and provide sufficient space for multiple cables or lines. The gland is supplied in packages of 100 pieces, making it suitable for larger installations or series mounting.

Polychloroprene rubber is an elastic material known for its high mechanical strength, weather resistance, and chemical resistance. It is particularly suitable for use in indoor and outdoor environments where it is exposed to long-term stresses from temperature fluctuations, moisture, or mechanical strain. The material selection ensures a long service life and reliable performance of the gland throughout its entire operational period.

Protective function and cable guidance are the central tasks of this cable gland. It prevents cables from being damaged by sharp edges during routing through openings, and simultaneously provides structured guidance that minimizes tangling or knotting of the lines. The elastic shape of the material allows for a secure fit without placing pressure on the cables.

The gland is designed for use in electrical and electronic installations, particularly in buildings where proper and safe cable routing is required. It is often used in conjunction with cable protection conduits, switch boxes, or other installation components to ensure the integrity of the lines. The use of cable glands is especially beneficial when multiple cables are routed through a single opening, as it enables even distribution and guidance.

Compatibility with other installation components is ensured, as the gland features standardized dimensions. It fits into common cable gland openings and can be used with various cable types, such as electrical wiring or data cables. Installation requires no additional tools or mounting aids; the gland is simply inserted into the opening and adapts to the shape due to its elasticity.

Installation is performed by simply inserting the gland into the designated opening. The elastic structure of the polychloroprene rubber ensures that the gland conforms to the shape of the opening and provides a secure hold. No additional fastening is required, as friction and shape adaptation are sufficient to keep the gland in place. Installation is therefore quick and can be done without special tools.

The gland is black, making it visually unobtrusive and allowing it to blend well into most installation environments. The color is part of the product designation and corresponds to the standard version. The packaging unit contains 100 pieces, which is advantageous for larger projects or series installations. The weight specification of 3.72 g per piece is technically relevant, particularly for planning transportation and storage conditions, but is not directly decisive for the user during operation.

Operational advantages include easy handling, high mechanical stability, and long service life. The gland requires no maintenance and remains functional over extended periods, even under stress from temperature and humidity fluctuations. The use of polychloroprene rubber ensures high resistance to aging and chemical influences, increasing reliability in use.

The Helavia DA 130/170/20 black is thus a reliable and standardized component for cable installation, suitable for use in both new construction and renovation projects. The combination of elastic material, standardized dimensions, and simple installation makes it a practical element in electrical and IT installations.
