The DH 250/310/330 cable glands from Ses-Sterling are black-coloured shaped parts made of polychloroprene rubber, specifically designed for use in electrical and installation technology. They serve as cable protection and cable entry components in switch cabinets, distribution boxes or other electrical enclosures, enabling cables to be safely and tightly passed through the enclosure wall. The glands belong to the HELAVIA product group and are made of an elastic, durable material that provides reliable sealing and mechanical protection.

Applications
These cable glands are intended for use in industrial and commercial installations as well as in electrical installations. They are particularly suitable for protecting cables against mechanical stresses such as friction, pressure or bending, and for achieving a tight connection between cable and enclosure. They are typically used in switchgear, distributors or other electrical cabinets where secure and durable cable entry is required. The glands are designed for indoor use, with the material offering a certain resistance to environmental influences such as moisture or temperature fluctuations.

Functions and Features in Detail
The glands are designed as rubber glands and allow for elastic adaptation to different cable diameters within the specified range. The shape ensures that the cable is securely held after insertion, achieving secure fixation and preventing movement. The surface is smooth and black, enabling good integration into technical installations. The glands are not equipped with additional fastening elements or threaded fittings; they function purely through elastic tension and form-fit.

Technology Explained Simply
The glands are made of polychloroprene rubber, a synthetic elastomer known for its high elasticity, chemical resistance and resistance to ageing. This material enables a tight and even enveloping of the cable, ensuring mechanical protection and sealing against dust and moisture. The elastic properties allow the glands to adapt to various cable diameters without damaging the cable. The black colour is part of the product design and serves visual harmonisation in technical installations.

Compatibility and Accessories
The DH 250/310/330 cable glands are designed for use with cables having diameters of 250 mm, 31牌 mm and 330 mm. They are intended for use as individual components and can be mounted in various switch cabinets or distributors, provided the hole or opening has the required size. The glands are not connected to additional components such as fittings, seals or fastening elements; they are inserted directly into the enclosure wall. Installation requires no additional tools or mounting aids – the elastic shape provides the necessary hold.

Installation and Mounting
Mounting is done by simply inserting the gland into the designated opening in the enclosure. The cable is already inserted into the gland before installation, so that after insertion, the gland holds the cable securely and simultaneously creates a tight connection to the enclosure. The elastic tension of the material ensures a secure fit without additional fastening. The glands are designed for single-use mounting; re-use is not intended, as the elastic properties may be impaired after the first use.

The glands are available in a package containing 25 pieces. The packaging serves storage and transport safety and is not part of the technical function.

Operational Advantages
The use of these cable glands ensures a secure and tight cable entry, protecting against mechanical damage and environmental influences. The elastic adaptation to various cable diameters increases installation flexibility. The material quality ensures long service life and resistance to ageing, enhancing reliability during operation. The simple installation without additional tools or fastening elements reduces installation effort and shortens mounting time.
