A conduit gland, also known as a bushing, is a mechanical fitting designed to provide a secure, sealed entry point for electrical cables into conduit systems. It prevents the ingress of dust, moisture, and other contaminants while offering strain relief and grounding continuity in industrial wire harness installations. These components ensure electrical safety and system integrity in harsh environments.

定义
A conduit gland, also known as a bushing, is a mechanical fitting designed to provide a secure, sealed entry point for electrical cables into conduit systems. It prevents the ingress of dust, moisture, and other contaminants while offering strain relief and grounding continuity in industrial wire harness installations. These components ensure electrical safety and system integrity in harsh environments.
工作原理
The conduit gland works by compressing a sealing element (such as a rubber gasket or neoprene seal) around the cable when the gland nut is tightened. This creates a watertight and dustproof seal while mechanically securing the cable to prevent pull-out. The metallic body provides grounding continuity between the cable armor (if present) and the conduit system.

常见问题

What is the difference between a conduit gland and a bushing?

While often used interchangeably, a gland typically provides sealing and strain relief, while a bushing primarily prevents cable abrasion at conduit entry points. Many modern products combine both functions.

How do I select the right conduit gland for my application?

Consider cable diameter, environmental conditions (IP rating), material compatibility, thread type, and any required certifications (like ATEX for hazardous areas). Always follow manufacturer specifications.
