General
Colour	Black

The Ses-Sterling Helavia DC 190/250/65 black is a cable gland made of polychloroprene rubber, specifically designed for use in electrical and IT installations. It provides secure and tight cable guidance through installation shafts, wall penetrations, or other components, while simultaneously offering mechanical protection and sealing against dust and moisture. The designation DC 190/250/65 refers to the technical dimensions: an outer diameter of 190 mm, an inner diameter of 250 mm, and a length of 65 mm. The gland is black, making it suitable for use in technical installations and industrial environments.

Cable glands are standard components for cable penetration, frequently used in electrical installations to protect cables from mechanical stress, such as friction or pressure. The Helavia DC 190/250/65 is part of the HELAVIA product group, manufactured from high-quality polychloroprene rubber (PCP). This material is characterised by high mechanical strength, weather resistance, and good elasticity, making the gland suitable for use in various environments. The black colour is typical for industrial and technical applications, as it integrates well visually into technical installations.

Functions and equipment in detail

The gland enables secure and tight cable guidance through components, with the elastic structure of the polychloroprene rubber ensuring a tight fit against both the cable and the penetration opening. The dimensions of 190 mm (outer diameter), 250 mm (inner diameter), and 65 mm (length) are designed for larger cable bundles or multiple cables within a penetration system. The gland is supplied in a pack of 50 pieces, making it suitable for large-scale installations or series mounting. The weight specification of 7.51 g per piece results from the material and dimensions and is typical for rubber components of this size.

Technology explained simply

Polychloroprene rubber (PCP) is a synthetic elastomer known for its high resistance to weathering, UV radiation, and mechanical stress. The gland utilises these properties to ensure long-term, tight, and mechanically stable cable guidance. The elastic structure allows adaptation to different cable diameters within the specified range, achieving a secure seal. The gland is not intended for use in explosive atmospheres, as no specific approvals or protection types (such as Ex) are mentioned.

Compatibility and accessories

The Helavia DC 190/250/65 is designed as a single component for use in cable penetrations. However, it can be used in combination with other installation elements such as cable protection conduits, wall penetrations, or switchboards, provided the dimensions match. Installation requires no additional tools or mounting aids; the gland is simply inserted directly into the penetration opening and adapts via its elasticity.

Mounting and installation

Installation is carried out by simply inserting the gland into the designated penetration opening. The elastic structure of the material ensures that the gland conforms to the shape of the opening and provides a tight fit. Cables are routed through the central opening, with the gland providing mechanical protection.

Advantages in operation

The Helavia DC 190/250/65 offers reliable and tight cable guidance, protecting against mechanical damage and environmental influences. The use of polychloroprene rubber ensures long service life and weather resistance, making the gland suitable for indoor and outdoor use. The pack of 50 pieces enables efficient handling in larger installations. The gland requires no additional mounting aids or tools, which speeds up and simplifies installation.
