Cable glands are used to attach and secure cables to equipment or to pass them through bulkheads or enclosures. The characteristics of cable glands include:
Protection: Cable glands provide protection against environmental factors such as dust, moisture, and dirt. They also protect cables from damage caused by pulling or twisting.
Seal: Cable glands create a seal between the cable and the equipment, preventing the ingress of moisture, dust, or other contaminants.
Strain relief: Cable glands provide strain relief to the cables by absorbing the tension caused by cable weight or vibration, which helps to prevent damage to the cables.
Material: Cable glands can be made from a variety of materials such as plastic, brass, stainless steel, or aluminum. The material chosen will depend on the application and the environment.
Thread: Cable glands have a threaded design that enables them to be screwed into place, providing a secure connection and preventing the gland from coming loose.
Size: Cable glands come in various sizes to accommodate different cable diameters.
Certification: Some cable glands are certified to meet specific standards, such as ATEX or UL, which ensures they are safe to use in hazardous environments.
Cable glands are essential components in electrical and electronic installations, and their main functions include:
Cable retention: The primary function of cable glands is to secure and retain cables in place. They prevent cables from being pulled out of equipment or enclosures due to vibration, movement, or external forces.
Cable sealing: Cable glands provide a secure seal around the cable entry point, preventing the ingress of dust, water, or other contaminants. This helps to protect the cable and the equipment from damage.
Strain relief: Cable glands provide a strain relief mechanism that helps to distribute the weight of the cable evenly, reducing the risk of damage to the cable or the equipment.
Grounding: Cable glands can be used to provide an electrical ground connection between the cable and the equipment or enclosure.
Hazardous area protection: Cable glands can be designed to provide protection against explosion or fire in hazardous areas, ensuring that electrical installations remain safe and compliant with industry standards.
