General
Colour	Black

The Helavia DA 40/80/20 black from Ses-Sterling are cable glands made of polychloroprene rubber, specifically developed for use in electrical and installation technology. These gum tubes provide secure and tight guidance of cables and lines through drill holes in components such as wall or ceiling panels. The glands are available in the colour black and offer reliable mechanical and electrical insulation. They are part of the HELAVIA product group, which specialises in shaped parts made from high-quality elastomer.

Applications
These cable glands are used in electrical installations to guide cables through drill holes in components, preventing mechanical damage or unintended electrical contacts. They are particularly suitable for indoor use, where tight and flexible cable guidance is required. The glands support the proper installation of lines in wall or ceiling structures and contribute to compliance with safety and installation standards.

Functions and Equipment in Detail
The Helavia DA 40/80/20 black are designed as crimping nipples, adapting to cable diameters through their shape and material properties. The glands feature an internal diameter adjustment, enabling secure and tight encasement of the cable. The material choice of polychloroprene rubber ensures high flexibility, weather resistance, and mechanical strength. The glands are suitable for a wide range of cable diameters, with the exact fit achieved through the elastic deformation of the material.

Technology Explained Simply
The glands operate on the principle of the crimping nipple, where the material elastically compresses around the cable as it is pulled through the opening. This creates a secure, tight fit that absorbs mechanical stress and tensile forces. Polychloroprene rubber is known for its high resistance to UV radiation, ozone, and chemical influences, extending the service life of the glands in various environments. The black colour is standard and blends visually into most installation scenarios.

Compatibility and Accessories
The Helavia DA 40/80/20 black are universally applicable and can be combined with various cable types, as long as their diameter falls within the adjustment range of the glands. They are part of the HELAVIA product line and can be combined with other shaped parts from this series to create complex installation systems. The glands are not specifically designed for particular brands or systems, but serve as universal components in electrical installations.

Installation and Mounting
Installation is performed by simply inserting the gland into the drill hole and then pulling the cable through. The elastic shape of the material ensures the cable is securely held without requiring additional fastening elements. The glands are designed for easy handling and do not require special tools. The packaging unit contains 100 pieces, sufficient for larger installations.

Operational Advantages
The Helavia DA 40/80/20 black provide reliable and tight cable guidance, minimising mechanical stress and electrical interference. The polychloroprene rubber material ensures long service life and high resistance to environmental influences. The glands are easy to install and do not require additional fastening elements, reducing installation time. The black colour is discreet and blends into most installation scenarios without causing visual disturbances.
