What is a Cable Gland?

Cable glands, also known as cable connectors or fittings, are essential components used to secure and terminate cables in electrical installations. These devices provide strain relief and ensure a secure connection, preventing cables from being pulled out or twisted. One of the most critical features of cable glands is their ability to maintain the integrity of the cable entry point. A waterproof cable gland offers enhanced protection against water ingress, making it ideal for use in harsh environments and outdoor applications. By sealing the cable entry, it ensures that electrical systems remain safe and operational, even under challenging conditions.
