Kabelgjennomføringer

Kabelgjennomføringer, also known as cable glands or cord grips, are mechanical devices designed to attach a cable, cord, or hose to an enclosure. Their primary function is to provide a seal against the ingress of dust, water, and other contaminants, and to relieve strain on the cable. This protection is crucial in industrial, electrical, and electronic applications where cables are exposed to harsh environments or subjected to movement.

The basic design of a cable gland typically involves a body, a sealing nut, and a clamping ring. When the cable is inserted through the gland, the clamping ring compresses the sealing element against the cable jacket, creating a watertight and dust-tight seal. The clamping ring also grips the cable, preventing it from being pulled out of the enclosure and reducing stress on the internal connections.

Cable glands are manufactured from various materials, including plastic (like nylon), brass, stainless steel, and aluminum, depending on the intended application and the environmental conditions. They come in a wide range of sizes to accommodate different cable diameters. Different types of cable glands exist to suit specific needs, such as explosion-proof glands for hazardous areas, high-temperature glands, and glands designed for specific cable types like armored cables. The proper selection and installation of cable glands are essential for ensuring the safety, reliability, and longevity of electrical and mechanical systems.
