General
Colour	Black

The Ses-Sterling Helavia DH 130/200/150 black 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 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 offering mechanical protection against damage. The designation DH 130/200/150 refers to the specific dimensions of the glands, designed for precise installation in drill holes with diameters of 130 mm, 200 mm, or 150 mm.

Applications
These cable glands are used in industrial and commercial electrical installations, particularly for routing power or low-voltage lines through components such as concrete, metal, or wood. They are suitable for indoor use and can be applied in various installation scenarios where tight and impact-resistant cable guidance is required. The glands support compliance with safety and fire protection regulations by forming a mechanical barrier against cable damage and ensuring proper cable routing.

Functions and Equipment in Detail
The rubber glands are made of polychloroprene rubber, an elastic and durable material offering high flexibility and resistance to mechanical stress. The glands are manufactured in black, making them visually unobtrusive in technical installations. The shape of the glands is designed for easy insertion into drill holes, ensuring a secure and tight fit. The glands are intended for single-use installation and serve as fixed cable guidance elements.

Technology Explained Simply
The cable glands function as mechanical guidance elements inserted into pre-drilled openings. The cable is routed through the gland, providing protection against mechanical influences such as friction, pressure, or bending stress. The polychloroprene rubber material offers high elasticity, allowing the glands to adapt to the shape of the drill hole and create a tight, non-slip connection.

Compatibility and Accessories
The glands are designed for drill holes with diameters of 130 mm, 200 mm, and 150 mm, with the type designation DH 130/200/150 specifically indicating the respective hole sizes. They are compatible with standard installation techniques and can be used in combination with other installation components such as cable protection conduits, switch boxes, or wall penetration fittings.

Installation and Mounting
Installation is performed by inserting the gland into the pre-drilled opening. The elastic structure of the polychloroprene rubber allows for easy yet secure fitting. The cable is routed through the gland, which ensures tight guidance. No additional tools or mounting aids are required. The glands are intended for single-use and are not designed for repeated mounting or dismounting.

Operational Advantages
The rubber glands provide reliable mechanical protection for cables and lines, thereby increasing the lifespan of the installation. The elastic structure ensures a tight fit, protecting against cable wear. The glands are black, enabling unobtrusive integration into technical installations. The use of polychloroprene rubber ensures high resistance to mechanical stress and long service life in operation.

The glands are supplied in a pack of 100 pieces, with each piece weighing 8.43 g. The packaging weight is 0.843 kg. The glands are intended exclusively as individual components for cable guidance.
