Information of the 139th Canton Fair 2026
The China Import and Export Fair (Canton Fair), founded on April 25, 1957, is held in Guangzhou every spring and autumn. Jointly hosted by the Ministry of Commerce and the People’s Government of Guangdong Province, and organized by the China Foreign Trade Centre, it is a comprehensive international trade event with the longest history, highest level, largest scale, most complete product categories, largest number of global buyers, widest country distribution, and best transaction results in China, known as “China’s No.1 Exhibition”.

In the electrical world, cable glands are essential for storing cables securely and managing their installation properly. Many manufacturers and users of cable glands frequently ask the same question; 

When working with electrical connections, it is essential to have appropriate protection, sealing, and strain relief. The cable glands are vital to performing these functions. 

Double compression cable glands are a critical part of many electrical systems; these components are made to anchor and seal cables entering into electrical equipment or enclosures securely. 

A waterproof cable gland is an electrical connection sealing device that connects and protects electrical cables that pass through, or connect with, enclosure, equipment or panel openings.

In this article, we’ll explain what cable gland size means, discuss its importance, and explore the different types of cable glanding. 

A cable gland, also known as a cable connector or strain relief, is a device used to securely attach and seal cables to electrical equipment. These components protect cables against wear, environmental damage, and provide grounding for electrical continuity in industrial or residential setups.

A cable gland, essential for cable-equipment interfaces, offers fixation, sealing (IP54-IP68), mechanical protection, grounding/shielding and explosion protection. Classified by material (metal for high-end, plastic for general use), it’s selected by protection level, cable specs and environment, crucial for equipment safety and advancing toward miniaturization/integration.

In cable connection systems, glands serve as core linking components, and their performance directly determines the stability, safety, and service life of the entire circuit. Nickel-plated brass cable glands, leveraging the dual advantages of a brass base material and a nickel plating layer, have become a preferred choice in multiple fields such as industry, communications, and automotive. They not only address the limitations of pure metal materials in complex environments but also establish a reliable connection barrier with their excellent comprehensive performance.
