How do cable glands work?

What is cable gland?


Cable glands are "mechanical cable entries" that attach to the ends of cables to secure them to any equipment. They are also commonly referred to as cable connectors, cable splices, wire clips or cable strain reliefs.


Cable glands are essential for terminating cables in harsh or hazardous areas where sealing and ingress protection are required. These are important for electrical equipment and switchgear as they provide stress relief and can also be attached to the aluminium jacket or armour of the cable.


Purpose of using cable glands:


As a mechanical cable entry, cable glands can be made of metallic or non-metallic materials. Cable glands are required in many industries that use them in conjunction with cables and wiring used in electrical instrumentation and automation systems. They are used for all available sizes and types of cables. Its main function is to safely pass pipes, wires or cables through the enclosure. However, they also need to protect electrical components from flames that can occur in hazardous areas.


How do cable glands work?


Cable glands are mainly used as sealing devices to protect the enclosure of electrical equipment. In addition, they act as a seal at the intake point and stop any damage to electrical systems and cables caused by external impurities. Environmental contaminants such as dirt, liquids, or water can damage cable connectors or cause them to become detached from electrical components. Therefore, the cable gland prevents the cable from being pulled or twisted out of the machine.


The installation of cable glands should follow the necessary codes of practice and local regulations.

It should also meet the manufacturer's guidelines.

Installation of cable glands must be carried out by competent and experienced personnel.

He or she must have the necessary expertise and be proficient in the installation of cable glands.

Furthermore, training can be facilitated.
