The Helavia DA 230/300/30 black from Ses-Sterling are cable glands made of polychloroprene rubber, specifically designed for use in electrical and installation technology. These rubber glands provide secure and tight guidance of cables and lines through holes in metal or plastic components, for example in enclosures, distribution boxes or machine housings. The glands are black and offer reliable mechanical and electrical insulation, making them suitable for both indoor and outdoor use. The designation DA 230/300/30 refers to the technical dimensions and fit for specific hole sizes.

Cable glands are an essential component in professional cable installation, as they provide mechanical protection and ensure a tight seal over the hole. The glands prevent dust, moisture or other particles from entering electrical assemblies. The material base of polychloroprene rubber (PCP) is characterised by high elasticity, weather resistance and chemical resistance, making the glands suitable for various operating conditions. The black colour is standard and meets typical requirements in electrical installation.

Functions and equipment in detail include a precise fit for holes with a diameter range of 230 to 300 mm, with the glands featuring an internal hole of 30 mm. These dimensions allow multiple cables or lines to be guided simultaneously through a larger hole, with the glands adapting elastically to ensure a tight seal. The glands are designed for easy installation and can be inserted into the hole without tools. The material strength ensures that the glands retain their shape even under mechanical stress and do not crack or deform.

Technology explained simply shows that the glands are made of an elastic rubber material that can be easily stretched during installation to fit into the hole. Once seated in the hole, the glands contract due to their elasticity, forming a tight fit. This fit prevents the glands from slipping and ensures a permanent seal. The material composition of polychloroprene rubber offers high resistance to UV radiation, ozone and atmospheric influences, making the glands suitable for outdoor use as well. The glands are not intended for use in aggressive chemical environments unless specified in the technical data sheet.

Compatibility and accessories include use in combination with various cable types, particularly electrical wiring, data cables or control lines. The glands are suitable for holes in metal and plastic enclosures, with the hole diameter ranging from 230 to 300 mm. The internal hole of 30 mm allows multiple cables to be guided simultaneously, with the glands ensuring secure and tight guidance. There are no specific accessory items mentioned in the manufacturer's catalogue, so the glands are used as standalone components.

Installation and mounting are done without tools. The glands are simply inserted into the designated hole, with the elastic shape ensuring they adapt to the hole and form a tight seal. Installation is quick and requires no additional tools. The glands are designed for single use and should not be reused, as this could impair the sealing effect. The packaging contains 50 pieces, which is sufficient for larger installations.

Operational advantages include reliable sealing, easy installation and high material durability. The glands provide long-term mechanical protection and prevent moisture or dust from entering electrical assemblies. The use of polychloroprene rubber ensures a long service life and high reliability under various environmental conditions. The glands are thus an important component in the professional installation of electrical and electronic systems.
