General
Colour	Black

The Ses-Sterling Helavia DV 4/9 (10) black is a strain relief made of polychloroprene rubber, specifically designed for use in electrical and IT installations. It serves as a protective and guiding element for cables and wires, particularly at penetrations through walls, ceilings, or other components, where mechanical stress or pulling forces may occur. The designation DV 4/9 (10) refers to the technical dimensions and the packaging unit – here, 10 pieces per bag. The black color is typical for installation components used in technical systems or industrial environments.

Applications
The strain relief Helavia DV 4/9 (10) is primarily used in electrical installations, for routing data and control lines, and in industrial plant construction. It protects cables from mechanical damage, especially at points where they pass through openings. Use in combination with cable ties enables secure fastening and strain relief, thereby extending the service life of the wiring. Typical applications are indoors, where no special environmental conditions such as high humidity or extreme temperatures are present.

Functions and Equipment in Detail
The strain relief consists of a flexible, rubberized element that adapts to the shape of the penetration and simultaneously provides a secure hold for the cables. The designation DV 4/9 (10) indicates the specific dimensions: the inner diameters of the sleeve are 4 mm and 9 mm, allowing adaptation to different cable diameters. The packaging unit includes 10 pieces, supplied in a bag. The black color is standard and meets typical requirements for installation components in technical systems.

Technology Explained Simply
The Helavia DV 4/9 (10) is made of polychloroprene rubber, an elastic material offering high mechanical strength and flexibility. This material enables a tight fit at the penetration and simultaneously protects the cables from friction and mechanical stress. The strain relief is mounted at the point where the cable passes through an opening, ensuring that pulling forces acting on the cable are not directly transferred to the wire, but are instead diverted through the rubber element. This prevents the insulation from tearing or being damaged.

Compatibility and Accessories
The combination of strain relief and cable tie enables secure fastening and strain relief of the wiring. Use in conjunction with other installation components such as protective conduits or cable duct systems is possible, provided the dimensions and mechanical requirements are compatible. The Helavia DV 4/9 (10) is part of the HELAVIA product line from Ses-Sterling, specifically developed for use in electrical and IT installations.

Installation and Mounting
Mounting is done by simply inserting the strain relief into the penetration, with the cable passing through the rubber element. The cable is then secured with a cable tie to ensure a firm hold. Installation requires no special tools and can be quickly and safely performed by skilled personnel. The strain relief automatically adapts to the shape of the opening and ensures a tight, yet flexible, fit.

Operational Advantages
Using the Helavia DV 4/9 (10) increases the safety and service life of installed cables. The strain relief protects against mechanical stress and prevents insulation from tearing. The simple installation and use of standard cable ties make this product a practical solution for daily use in electrical and IT installations. The material quality of polychloroprene rubber ensures long durability and reliability under normal operating conditions.
