Kaapeliläpiviennin

Kaapeliläpivienti is a Finnish term referring to a cable gland or cable entry. It is a mechanical fitting used to secure and protect a cable where it passes through a bulkhead, enclosure, or housing. The primary function of a kaapeliläpivienti is to provide a seal against dust, water, and other environmental contaminants, as well as to prevent strain on the cable itself.

Kaapeliläpiviennit are crucial in many industrial, electrical, and electronic applications. They ensure the integrity of enclosures and prevent the ingress of harmful substances that could damage equipment or create safety hazards. By creating a tight seal, they also help maintain the environmental rating (e.g., IP rating) of the enclosure.

These devices typically consist of a body, a sealing gasket or O-ring, and a clamping mechanism. The cable is passed through the body, and the clamping mechanism, often a nut, compresses the gasket around the cable, creating the seal. Strain relief features are often incorporated to prevent the cable from being pulled or bent at an acute angle where it enters the enclosure.

Kaapeliläpiviennit are manufactured from various materials, including plastics like nylon and metal such as brass or stainless steel, depending on the specific application requirements regarding chemical resistance, temperature, and mechanical strength. They come in different sizes and thread types to accommodate various cable diameters and enclosure mounting holes. The correct selection and installation of a kaapeliläpivienti are essential for maintaining the safety and reliability of electrical and electronic systems.
