The Helavia DA 100/140/30 black from Ses-Sterling are cable glands made of polychloroprene rubber, specifically designed for use in electrical and installation technology. These
cable glands provide secure and tight guidance of cables or lines through drill holes in wall or ceiling structures. The glands are black in colour and enable a clean, professional cable installation, while simultaneously withstanding mechanical stress and environmental influences. The designation DA 100/140/30 refers to the technical dimensions: an inner diameter of 100 mm, an outer diameter of 140 mm, and a length of 30 mm. These dimensions are designed for use in standardised installation scenarios where a stable and tight fit is required.
Applications
These
cable glands are used in electrical installations, particularly for routing power and low-voltage lines through building components such as concrete, drywall, or metal plates. They are suitable for indoor use where a tight and mechanically stable cable guidance is necessary. The glands are frequently used in building electrics, for installing sockets, switches, or in IT infrastructure, where cables must be routed through walls or ceilings. Using cable glands ensures that cables are not damaged and a tight, dust- and moisture-proof connection is created.
Functions and Equipment in Detail
The Helavia DA 100/140/30 are made of
polychloroprene rubber, an elastic, durable material that offers high mechanical strength and good elasticity. The material allows for a secure, tight fit in drill holes and protects cables from mechanical damage such as friction or pressure. The glands are black, making them visually discreet and well-integrated in most installation scenarios. The shape is cylindrical with a conical entry edge, which facilitates cable insertion.
Technology Explained Simply
The
cable glands function as an elastic seal that is inserted into a drill hole and adapts to the shape of the opening. The elastic nature of the polychloroprene rubber ensures that the seal remains tight, even if the cables are slightly moved. The inner surface of the gland is smooth to avoid friction and damage to cable insulation. The glands are not self-cutting; they must be inserted into a pre-drilled hole. The dimensions of 100 mm inner diameter, 140 mm outer diameter, and 30 mm length are designed for standardised drill holes commonly used in electrical installations.
Compatibility and Accessories
The Helavia DA 100/140/30 are designed for use with cables and lines with a diameter up to 100 mm. They are not specifically designed for certain cable types but adapt to various cable diameters due to their elastic structure. The glands are not combined with additional components such as screw closures or sealing compounds.
Installation and Mounting
Installation is carried out by inserting the gland into a pre-drilled hole with a diameter of approximately 140 mm. The gland is positioned so that the conical entry edge facilitates cable routing. Cables are passed through the gland, and the elastic structure of the material ensures a tight fit. No additional fastening or tools are required. The glands are supplied in a pack of 100 pieces, suitable for larger installations.
Operational Advantages
The
cable glands provide reliable, tight, and mechanically stable cable guidance. The use of polychloroprene rubber ensures long service life and resistance to mechanical stress. The glands are easy to install and require no additional tools or materials. The black finish ensures discreet integration into the installation.
