The Helavia DA 30/70/20 black is a cable gland made of polychloroprene rubber, manufactured by Ses-Sterling. It serves as a protective and guiding element for cables and wires when passing through components such as enclosures, wall penetrations, or machines. The gland is black in colour and is supplied in a pack of 100 pieces. Its design allows for secure and tight guidance of cables with a diameter of up to 20 mm through a hole of 30 mm, with the total length of the gland being 70 mm. The material choice of polychloroprene rubber ensures high mechanical strength as well as resistance to ageing, oils, and chemical influences, making it suitable for use in industrial and technical installations.
Cable glands are specifically designed for the secure and tight guidance of cables. The Helavia DA 30/70/20 black is used in components where mechanical protection and sealing against dust or moisture are required. It is commonly used in electrical installations, machine and plant engineering, as well as in automation technology, where cables must be routed through enclosures or wall penetrations. The gland ensures that cables are not damaged and simultaneously creates a tight connection between the cable and the penetration element.
Polychloroprene rubber is an elastic material known for its high resistance to mechanical stress, temperature fluctuations, and chemical influences. It offers good elasticity, allowing the gland to adapt to the shape of the cable being routed and ensuring a tight seal. The black colour is typical for industrial applications and supports visual differentiation from other components.
The
cable gland is supplied in a pack of 100 individual pieces. The packaging has a total weight of 0.055 kg, with each individual piece weighing 0.55 g. These specifications refer to the manufacturer’s standard packaging and are relevant for storage and handling.
The gland is designed for cables with a maximum diameter of 20 mm and fits into holes with a diameter of 30 mm. It can be used in combination with other protective and guiding elements such as cable conduit systems or protective sleeves to ensure comprehensive protection. Installation requires no additional tools – the gland is simply inserted into the designated hole and adapts to the cable due to its elastic structure.
Installation is carried out by simply inserting the gland into the hole of the component. The elastic structure of the material ensures that the gland adapts to the shape of the hole and provides a tight seal around the cable. No special installation aids or tools are required. The gland is designed for use in static applications where no high dynamic loads occur. Use in moving or vibrating systems is not recommended, as this could reduce the gland’s service life.
In operation, the Helavia DA 30/70/20 black provides reliable protection for cables and wires. The tight seal prevents the ingress of dust, moisture, or small particles, thereby increasing the service life of the cables and the reliability of the electrical connection. The high mechanical strength of the material protects cables from mechanical damage, especially when routed through components. Use in outdoor environments is not explicitly recommended unless the environmental conditions meet the material’s requirements.
