Kabelindføring

Kabelindføring, often translated as cable gland or cable entry, refers to a device used to create a secure and environmentally sealed connection between a cable and an enclosure. Its primary function is to protect the enclosure's interior from external contaminants such as dust, water, oil, and chemicals, while also preventing the cable from being damaged or pulled out.

These devices are crucial in industrial, commercial, and sometimes residential applications where electrical or electronic equipment needs to be protected from harsh environments. They come in various materials, including metal (like brass or stainless steel) and plastic, chosen based on the specific application's requirements for strength, corrosion resistance, and chemical compatibility.

The design of a kabelindføring typically involves a threaded body that is mounted into a pre-drilled hole in the enclosure. A sealing ring or gasket provides the initial barrier, and a clamping mechanism, often a nut and a cone-shaped seal, compresses around the cable's outer sheath. This compression ensures a tight seal and provides strain relief, preventing excessive bending or pulling forces from damaging the cable's internal conductors.

Different types of kabelindføring exist to accommodate various cable diameters, thread sizes, and environmental protection ratings (IP ratings). Explosion-proof cable glands are specifically designed for hazardous areas where flammable gases or dust may be present, requiring robust construction and specialized sealing properties to prevent ignition. Proper installation is vital to achieving the intended seal and protection.
