General
Colour	Black

The Helavia DA 300/350/15 black from Ses-Sterling are cable glands made of polychloroprene rubber, designed for use in electrical and installation technology. These rubber glands provide secure and tight cable or conduit guidance through holes in enclosures, control panels, or other components. The glands are black, enabling a clean, mechanically robust, and flexibly adaptable passage that protects against mechanical stress as well as environmental influences such as moisture or dust. The designation DA 300/350/15 refers to specific dimensions and application parameters intended for precise fitting into standardized holes.

Applications
These cable glands are particularly suitable for use in industrial and commercial installations where tight and mechanically stable cable guidance is required. They are commonly used in enclosures, distribution boxes, machine and plant construction, and electrical installations. The glands are designed for guiding cables through holes with a diameter of 300 to 350 mm, with the specification “/15” indicating a specific design variant or additional technical designation defined within the Helavia product range. Use in electrical installations ensures proper and standard-compliant cable routing.

Functions and Equipment in Detail
The glands are made of polychloroprene rubber, an elastic and durable material offering high flexibility and good mechanical strength. The material selection enables a tight seal of the hole, preventing uncontrolled ingress of dust, moisture, or other particles. The black surface is resistant to UV radiation and chemical influences, increasing durability under real operating conditions. The glands are designed to elastically adapt to the shape of the passing cables, ensuring secure, crack-free guidance.

Technology Explained Simply
The designation DA 300/350/15 describes the specific design of the glands, intended for holes with a diameter range of 300 to 350 mm. The specification “/15” refers to an internal designation within the Helavia product line and may indicate a specific length, cross-section, or other technical specification relevant to the application. The glands are made of polychloroprene rubber, a material known for its elasticity, weather resistance, and chemical resistance. The black surface is not only visually uniform but also functional, as it resists UV radiation and oxidation.

Compatibility and Accessories
The Helavia DA 300/350/15 black are individual components intended for installation in existing systems. They are compatible with holes in the specified diameter range and can be used with various cable types, such as electrical wiring or data cables. The glands are part of the HELAVIA product series and can be combined with other components of this series to ensure a consistent and uniform installation.

Installation and Mounting
Installation is performed by simply inserting the glands into the designated hole. The elastic shape of the polychloroprene rubber allows for a secure and tight fit without requiring additional tools or adhesives. The glands are designed to adapt to the shape of the hole and provide a tight seal. Installation typically requires no tools, with cables being routed through the opening after the glands are inserted. Mounting is quick and requires no additional accessories.

Operational Advantages
The use of Helavia DA 300/350/15 black provides reliable and tight cable guidance, increasing the lifespan of the installation. Material strength and resistance to environmental influences ensure long durability, even under demanding conditions. Easy installation and high precision reduce installation time and minimize error risks. The glands are suitable for industrial and commercial applications where secure and tight cable guidance is critical.
