General
Colour	Black

The Ses-Sterling Helavia DV 7/12 (10) black is a strain relief made of polychloroprene rubber, specifically developed for use in electrical and IT installations. It serves as a protective and guiding element for cables and lines when passing through components, such as wall or ceiling openings, preventing mechanical stress caused by tensile forces. The product is available in black and is delivered in a packaging unit containing a bag weighing 58.3 g.

Strain reliefs are indispensable in electrical installations to protect cables and lines from mechanical damage, especially when they are routed through openings in components. The Helavia DV 7/12 (10) fulfills this function through its specific shape and material properties. The polychloroprene rubber offers high elasticity and resistance to mechanical stress, extending the service life of the cable connection. The designation DV 7/12 (10) refers to the specific dimensions and the number of units per packaging, where the numbers 7 and 12 indicate the inner diameters in millimeters suitable for cable routing.

Functions and equipment in detail

The strain relief is designed to adapt elastically while providing a secure hold for the cables. Its shape enables easy installation and ensures that cables are not damaged by tensile forces. The material is suitable for indoor use and offers a high degree of protection against mechanical influences. The packaging contains one unit, consisting of a bag that safely stores the strain reliefs.

Technology explained clearly

The Helavia DV 7/12 (10) is made of a flexible, rubber-like material that deforms under pressure, thereby protecting the cables. The polychloroprene rubber is a synthetic elastomer known for its high resistance to wear, aging, and chemical influences. The strain relief is inserted into an opening in a component, with the cable routed through the interior of the strain relief. The shape ensures that the cables do not rub directly against the edge of the opening, which could cause mechanical stress.

Compatibility and accessories

The strain relief is designed for use with cables and lines having a diameter between 7 mm and 12 mm. It is part of the product group Formteile HELAVIA and is used in electrical and IT installations to protect cable connections. It is used in conjunction with other installation elements, such as cable ties, which are used to secure the cables. The exact installation depends on the application, with the strain relief being inserted into the opening and the cable routed through its interior.

Installation and mounting

The installation of the Helavia DV 7/12 (10) is done by simply inserting it into the appropriate opening. The strain relief adapts elastically to the shape of the opening and provides a secure hold. The cable is routed through the interior of the strain relief, thereby avoiding mechanical stress from tensile forces. The installation requires no additional tools or aids, as the strain relief’s shape and material properties enable easy mounting.

Advantages in operation

Using the Helavia DV 7/12 (10) provides high protection for cables and lines, especially in areas where mechanical stress occurs. The polychloroprene rubber ensures a long service life and high resistance to wear. The strain relief is easy to install and requires no additional tools, speeding up the installation process. The black color blends in with most installation scenarios and is therefore unobtrusive in use.

Areas of application

The strain relief is suitable for electrical and IT installations to protect cables and lines when routed through components. It is commonly used in residential and commercial buildings where cables are routed through walls, ceilings, or other components. It is used in conjunction with other installation elements to ensure a safe and long-lasting cable connection.

Scope of delivery

The packaging contains a bag with the strain relief Helavia DV 7/12 (10) in black. The information refers exclusively to the strain reliefs contained in the bag.
