Metric Cable Gland

A metric cable gland is a device designed to attach and secure the end of a cable to the equipment. It's typically used to ensure the protection of electrical equipment and maintain the integrity of the enclosure into which the cable is entering. The term "metric" refers to the standard unit of measurement used for the size of the gland, which is in millimeters (mm).

Why Use Metric Cable Glands?

Standardization: Metric cable glands conform to international standards, making them universally applicable across various regions and industries.
Precision: The use of metric measurements allows for precise sizing, ensuring a snug fit that reduces the risk of wear and tear on cables.
Versatility: Suitable for various cable types, including armored, unarmored, and braided cables.

Key Features of Metric Cable Glands

Material: Available in various materials such as brass, stainless steel, aluminum, and plastic, each offering different levels of durability, corrosion resistance, and application suitability.
Sealing: Designed with IP (Ingress Protection) ratings, ensuring they provide a watertight and dustproof seal. This is crucial in harsh environments where equipment needs to be protected from external elements.
Thread Size: The metric measurement system provides precise thread sizes, which are essential for compatibility with international equipment and standards.

Applications of Metric Cable Glands

Industrial Automation: Used in control panels, junction boxes, and motor connections where precise cable entry is critical.
Marine and Offshore: Metric cable glands are often used in marine environments due to their robust sealing capabilities, protecting equipment from water and salt corrosion.
Renewable Energy: In solar and wind energy systems, where cables need to withstand environmental exposure, metric cable glands offer reliable protection.
