kábelbejáró

A kábelbejáró, sometimes referred to as a cable entry or cable gland, is a component used to securely introduce electrical cables into a piece of equipment or enclosure. Its primary function is to provide a sealed and protected passage for cables, preventing the ingress of dust, moisture, and other contaminants. This is crucial for maintaining the integrity and safety of electrical systems, especially in harsh environments.

These devices typically consist of a body, a sealing mechanism (often a rubber or plastic grommet), and a locking nut or clamping mechanism. The cable is passed through the body, and the sealing mechanism compresses around the cable to create a tight seal. The locking nut then secures the kábelbejáró to the enclosure wall.

Kábelbejárók are available in various materials, including plastic and metal, depending on the application and environmental considerations. They come in different sizes to accommodate cables of varying diameters. Beyond basic sealing, some advanced kábelbejárók offer features such as strain relief to prevent damage to the cable from pulling or bending, and electromagnetic interference (EMI) shielding.

The use of kábelbejárók is widespread across numerous industries, including manufacturing, telecommunications, renewable energy, and automotive. They are essential components in control cabinets, junction boxes, outdoor equipment, and any application where a protected and sealed cable entry is required. Proper selection and installation of a kábelbejáró are vital for ensuring the longevity and reliable operation of electrical installations.
