The Helavia DA 100/140/20 black from Ses-Sterling are cable glands made of polychloroprene rubber, designed for use in electrical and installation technology. They serve as protective and guiding elements for cables and wiring when passing through components such as wall or ceiling openings. The glands are black in colour and made of an elastic, dimensionally stable material that ensures a secure and durable fit. The designation DA 100/140/20 refers to the technical dimensions: an outer diameter of 100 mm, an inner diameter of 140 mm, and a length of 20 mm. These dimensions allow for precise adaptation to standard openings in building components and ensure secure cable guidance without mechanical damage.

Cable glands are specifically developed for use in electrical installations, where reliable and durable cable guidance is required. They are commonly used in building installations, for laying power and low-voltage lines, as well as in industrial electrical engineering. The glands prevent cables from being worn or damaged during passage through openings and simultaneously protect against mechanical influences such as friction or pressure. The use of polychloroprene rubber ensures high elasticity and resistance to ageing, UV radiation, and chemical influences, extending the service life of the glands.

Functions and equipment in detail include precise shaping that enables a tight fit in the intended openings. The glands are designed to adapt elastically and ensure a tight encasement of the cables. This reduces the risk of cable damage and increases the safety of the installation. The black colour is standard and visually matches most installation scenarios. The glands are not supplied with additional components such as fastening elements or tools; they are inserted directly into the designated opening and held securely by elastic tension.

Technology explained simply shows that the glands are made of an elastic polymer that can be easily stretched during installation to fit into the opening. Once the tension is released, the material contracts again and tightly encloses both the cable and the opening. This principle ensures a secure and durable fixation without additional fastening elements. The choice of polychloroprene rubber provides high resistance to environmental influences, making the glands suitable for use in indoor and outdoor environments, provided there are no specific conditions such as high temperatures or aggressive chemicals.

Compatibility and accessories refer to use in conjunction with standard installation components such as wall or ceiling penetrations. The glands are designed for openings with an outer diameter of 100 mm and fit into corresponding drill holes or pre-fabricated penetrations. They are not specific to particular brands or models, but are designed as universal components for electrical installations.

Installation and mounting is carried out by simply inserting the glands into the designated opening. The elastic design ensures that the glands automatically adapt to the shape of the opening and create a secure connection. No tools or additional mounting effort is required. The glands are designed for single-use mounting and cannot be reused, as the elastic shape cannot be fully restored after the first installation.

Operational advantages include easy handling, high safety, and long service life. The glands protect cables from mechanical damage and ensure a proper installation that meets the requirements of electrical installation. The use of polychloroprene rubber ensures high resistance to environmental influences, extending the service life of the glands and reducing the need for maintenance. The glands are available in a pack of 100 pieces, making them suitable for larger installations.

The glands are not supplied with additional materials such as adhesives, fastening elements, or instructions. The packaging contains exclusively 100 pieces of black glands. The specifications refer exclusively to the described dimensions, material, and colour.
