The Helavia DA 230/300/20 black from Ses-Sterling are cable glands made of polychloroprene rubber, specifically designed for use in electrical and installation technology. These rubber glands ensure safe and tight cable and wire routing through components such as wall penetrations, enclosures, or switch cabinets. The glands are black in colour and enable a clean, professional cable installation, while simultaneously withstanding mechanical stress and environmental influences. The designation DA 230/300/20 refers to the technical dimensions: an outer diameter of 230 mm, an inner diameter of 300 mm, and a length of 20 mm. These dimensions are suitable for use in larger penetrations and for cable bundles with high cross-sections.

Cable glands are an essential component in the installation of electrical systems, especially when a tight and flexible cable routing is required. The glands are typically used in wall penetrations or during the installation of switch cabinets to protect cables from mechanical damage, dust, and moisture. The use of polychloroprene rubber ensures high elasticity and resistance to ageing, ozone, and UV radiation, extending the service life of the glands in both outdoor and indoor environments. The material selection also ensures effective sealing, even under varying temperatures and loads.

Functions and features in detail include the ability to safely route cable bundles with a diameter up to 300 mm, while the glands themselves have an outer diameter of 230 mm. The length of 20 mm allows sufficient insertion into the penetration to ensure a stable and tight connection. The glands are manufactured in black, making them visually unobtrusive and well-integrated into industrial or technical environments. The packaging unit contains 50 pieces, suitable for larger installations or series mounting.

Technology explained simply shows that due to their elastic properties, the glands compress the cable slightly during insertion and then re-enclose it, creating a tight fit. The material polychloroprene rubber (PCP) is particularly suitable for applications requiring high mechanical load capacity and chemical resistance. The glands are not designed for power supply over the cable (PoE), but solely for mechanical cable guidance and protection. The black colour is standard and corresponds to the usual configuration for industrial applications.

Compatibility and accessories refers to use in combination with other installation elements such as wall penetrations, switch cabinets, or cable ducts. The glands are universally applicable and fit into standard penetrations with a bore or diameter of approximately 230 mm. There are no specific accessories recommended by the manufacturer; the glands are supplied as individual components and integrate seamlessly into existing installation systems. Installation requires no additional tools or mounting aids — the glands are simply pressed into the penetration and the cable is pulled through.

Installation and mounting is carried out by simply pressing the glands into the designated opening, where the elastic structure of the material ensures secure anchoring. The cables are then pulled through the glands, with the internal fit providing a tight enclosure around the cable. The mounting process requires no special tools, as the glands remain securely in place in the penetration due to their shape and material strength. The use is particularly advantageous when installing cables in damp or dusty environments, where tight sealing is necessary.

Operational advantages include easy handling, high mechanical stability, and long service life. The glands protect cables from mechanical damage, such as abrasion or pressure, and prevent the ingress of dust, moisture, or small particles. The material strength of polychloroprene rubber ensures reliable performance over a long period, even with frequent temperature fluctuations. The packaging unit of 50 pieces enables efficient use in larger projects, with glands being taken directly from the packaging and mounted. The black colour blends visually into most technical environments and is suitable for professional installations.
