The Helavia DA 185/250/10 black is a gland sleeve made of polychloroprene rubber, designed for use in electrical and installation technology. The manufacturer is Ses-Sterling, and the product is distributed under the manufacturer's number 02520343010. This sleeve serves for the safe and tight guidance of cables and lines through components, such as wall penetrations, enclosures or control panels. The designation DA 185/250/10 describes the technical dimensions: an outer diameter of 185 mm, an inner diameter of 250 mm, and a length of 10 mm. The sleeve is black, making it suitable for use in industrial and technical environments.

Gland sleeves are specially designed protective components that ensure mechanical and electrical insulation between cables and the components through which the cables are routed. The Helavia DA 185/250/10 is made of polychloroprene rubber (PCP), an elastic, durable material that offers high flexibility and resistance to mechanical stress, temperature fluctuations, and chemical influences. This material quality enables a tight, yet elastic adaptation to the cable surface, ensuring secure guidance and protection against mechanical damage.

Applications include particularly electrical installations in buildings, industrial plants, machine construction, and automation technology. The sleeve is used wherever cables must be routed through wall or ceiling penetrations, enclosures, or other components, and a tight, impact-resistant, and pull-resistant guidance is required. The dimensions of 185 mm outer diameter and 250 mm inner diameter allow use in larger penetrations, for example, during installation of heavy-duty power lines or when wiring machines with large enclosure openings.

Functions and equipment in detail include the elastic shape adaptation to the cable surface, ensuring a tight but non-damaging encasement. The length of 10 mm is designed for a short but sufficient penetration, enabling use in confined structures or limited space conditions. The black color is standard for industrial applications, as it integrates well visually into technical environments and offers high resistance to UV radiation and soiling.

Technology explained simply means that the sleeve, due to its elastic structure, encloses the cable and provides both mechanical stabilization and electrical insulation. The polychloroprene rubber ensures that the sleeve does not break or loosen even under frequent movement or vibration. The material composition ensures high resistance to aging, so the sleeve maintains its function over a long period. The precise fit between outer and inner diameter allows secure installation without additional tools.

Compatibility and accessories refers to use in conjunction with other installation elements, such as cable protection conduits, wall penetrations, or control panels. The Helavia DA 185/250/10 is designed for use with cables and lines whose diameter falls within the specified inner diameter of 250 mm. The sleeve is delivered in packages of 100 pieces, making it suitable for large-scale installations and series mounting.

Mounting and installation is carried out by simply inserting the sleeve into the designated opening and routing the cable through the interior of the sleeve. The elastic shape ensures that the sleeve automatically adapts to the cable shape and creates a tight encasement. No additional tools or mounting aids are required. The sleeve is suitable for use in both static and dynamic applications, provided the mechanical load remains within the specified limits.

Operational advantages lie in high reliability, easy installation, and long service life. The sleeve protects cables from mechanical damage such as friction, pressure, or pulling, and simultaneously prevents ingress of dust, moisture, or other environmental influences. The material quality ensures high resistance to environmental conditions, increasing maintenance-free operation and operational safety. The standardized shape and clear dimensions enable easy planning and integration into existing installation systems.
