What are the uses of cable glands?
Cable glands, also known as cable glands, cable grommets, cable bushings or cable glands, are electrical accessories that provide protection and sealing of cable entries. Glands allow for safe and solid routing of cables through the housings of electrical devices. The cable entry is precisely sealed, so the devices are effectively protected against moisture, dust and dirt, which extends their service life and allows for proper operation.
Additionally, the use of a bushing provides reliable protection against twisting the cable inside the equipment. The cable does not kink and becomes much more resistant to breakage or other mechanical damage, e.g. due to contact with sharp walls. A high-quality, correctly installed cable gland prevents the cable from being torn out of the electrical device. Thanks to cable glands, both cables and machines can be operated longer and more safely.
Cable glands are used to seal cable passages not only in the energy sector, but also in telecommunications, power engineering, control, chemical, food and agricultural industries. They are used in rail and sea transport and in many other industries.
What to remember when installing cable glands?
The cable gland, as a rule, is easy to install even for novice installers. The special design facilitates the passage of cables through the housings of various electrical devices, machines and switchboards. The most important thing is to select cable glands with parameters adequate to the technical requirements of the installation and specific working conditions. It is worth buying glands only from proven manufacturers and suppliers, providing assurance of product quality and ease of installation.
What types of cable glands are there?
Cable glands have many applications, which is why there are various types of bushings on the market. They differ in terms of dimensions, material composition, degree of protection, resistance to extreme temperatures, thread type, additional protection, and even color. Special attention should be paid to the gland's intended use for cables with specific diameters. For example, a model for cables with a diameter of 3 to 6.5 mm will work well in various types of electrical and telecommunications installations.
Cable glands are often divided according to the material they are made of. On this basis, we can distinguish:
Each cable gland, regardless of the material, as long as it has a solid construction, can offer excellent tightness and maximum resistance to shock, vibration and weather conditions.
