The DA 250/470/15 cable glands from Ses-Sterling are specifically designed for use in electrical and installation engineering. They serve as rubber glands to ensure safe and tight cable and wire routing through components such as wall penetrations, enclosures, or control panels. The glands are made of polychloroprene rubber, a robust and flexible material known for its high chemical resistance and weather resistance. The designation DA 250/470/15 refers to the technical dimensions: an outer diameter of 250 mm, an inner diameter of 470 mm, and a length of 15 mm. The glands are finished in black, making them suitable for use in industrial and technical environments.

Applications
These cable glands are particularly suitable for use in industrial electrical installations, for routing cables through wall or ceiling penetrations, as well as in enclosures and distributors. They provide mechanical protection for cables and prevent the ingress of dust, moisture, or other environmental influences. Use in installation engineering is typical, where tight and flexible cable routing is required. The glands are suitable for indoor and outdoor use, with the polychloroprene rubber material offering high resistance to UV radiation and atmospheric influences.

Functions and Features in Detail
The glands are designed as cable glands, meaning they are inserted into a pre-drilled opening to secure cable passage. The shape allows for a tight fit around the cable and simultaneous sealing of the penetration. The material thickness and design ensure that the glands maintain their function even under mechanical stress, such as tension or pressure. The black colour is not only aesthetic but also functional, as it protects the glands from UV discoloration and allows for seamless integration into technical installations.

Technology Explained Simply
The glands are made of polychloroprene rubber, a synthetic elastomer known for its high flexibility, heat resistance, and chemical resistance. This material enables a tight and elastic fit around cables, ensuring mechanical protection and long-lasting sealing. The dimensions of 250 mm outer diameter, 470 mm inner diameter, and 15 mm length are designed for use in larger penetrations, such as in enclosures or when routing multiple cables. The 15 mm length is sufficient to ensure secure anchoring in wall or enclosure openings.

Compatibility and Accessories
The glands are designed for use with cables and wires that fit within the specified opening. They are part of the HELAVIA profile parts product group, specifically developed for use in electrical installations. They can be used in combination with other HELAVIA profile parts to ensure a consistent and tight installation. The glands are not designed for a specific cable type but adapt elastically to various cable diameters, as long as they fall within the specified dimensions.

Installation and Mounting
Installation is carried out by inserting the glands into the pre-drilled opening, where the outer shape (250 mm diameter) fits into the wall or enclosure opening. The inner opening (470 mm diameter) allows cable passage. The glands are designed to adapt elastically and create a tight seal. No additional fastening is required, as the shape and material provide self-retaining anchoring. Installation is tool-free, with the glands simply pressed into the opening.

Operational Advantages
Using these glands provides reliable mechanical protection for cables and prevents environmental influences from entering. The high-quality polychloroprene rubber material ensures long service life and high resistance to weathering. The black finish is ideal for use in technical installations, as it integrates visually and is protected against UV discoloration. The glands are available in packages of 50 pieces, making them suitable for larger installations.
