General
Colour	Black

The Helavia DA 185/250/30 black from Ses-Sterling are cable glands made of polychloroprene rubber, designed for use in electrical and installation technology. These cable glands ensure safe and tight cable or wire guidance through components such as enclosures, wall penetrations, or control panels. The glands are black, enabling a clean, professional cable installation while simultaneously withstanding mechanical stress and environmental influences. The designation DA 185/250/30 refers to the technical dimensions: an inner diameter of 185 mm, an outer diameter of 250 mm, and a length of 30 mm. This specific configuration makes them particularly suitable for larger cable bundles or multiple wires in a single penetration.

Applications
These cable glands are used in industrial electrical installations, machine building, and building and plant cabling. They are especially suitable for installations requiring tight and flexible cable guidance. Due to the polychloroprene rubber material, they are resistant to oil, grease, solvents, and other chemical influences, making them suitable for technically demanding environments. The glands are intended for indoor and outdoor use, with the material properties providing a certain degree of weather resistance.

Functions and Features in Detail
The Helavia DA 185/250/30 black are designed as cable glands that, due to their shape and material composition, enable secure, tight, and elastic cable guidance. The polychloroprene rubber offers high elasticity, allowing the glands to adapt to the shape of the passing wires and provide a secure hold. The black surface is resistant to UV radiation and mechanical stress, extending the service life of the glands. The glands are not equipped with additional cable glands or fastening elements – they function purely through elastic fit and pressure sealing.

Technical Explanation
The glands are made of an elastic, rubber-like material that easily deforms when inserted into a hole or opening and then returns to its original shape. This elastic effect ensures that the glands tightly enclose the passing cables, providing mechanical and electrical insulation. The choice of polychloroprene rubber offers high chemical resistance, particularly against mineral oils, greases, and many organic solvents. The glands are not intended for use in aggressive chemical environments exceeding typical industrial requirements. The black color is standard and serves visual harmonization in technical installations.

Compatibility and Accessories
The Helavia DA 185/250/30 black are designed for use with cables and wires whose diameter falls within the specified range of 185 mm to 250 mm. The glands are not specifically designed for particular brands or models of cables, but adapt universally to the geometry of the wires being passed through. There are no specific accessories supplied or recommended with this item. The glands are delivered in a packaging unit of 100 pieces, suitable for larger installations or series mounting.

Installation and Mounting
Installation is performed by simply inserting the glands into the designated hole or opening. The elastic nature of the material allows for easy fitting, with the glands slightly deforming during insertion and then returning to their original shape. Cables are passed through the glands, with the elastic encasement ensuring tight and secure guidance. No additional tools or fastening elements are required. The glands are not designed for repeated mounting – they are intended for single-use only.

Operational Advantages
The Helavia DA 185/250/30 black provide reliable, tight, and mechanically stable cable guidance. The polychloroprene rubber material ensures long service life under industrial conditions. The glands are easy to install and require no additional fastening elements. The black surface blends visually into technical installations. The packaging unit of 100 pieces enables cost-effective use in larger projects. The glands are not intended for use in extreme temperatures or highly corrosive environments, which is not required in normal operation.
