Cable glands play many important roles in cable management. Designed to attach and fix the end of the cable and its connection to, the cable gland of the device provides grounding, grounding, insulation, bonding and strain relief. They can also be used to seal cables passing through the gland partition.
They are usually located in dangerous or harsh environments that require electric sparks containing flames or repel external contaminants such as dust, dirt and liquids. In addition, their job is to prevent the cable from twisting or pulling to ensure a strong connection and continuous performance.
So how do you know which cable gland is suitable for your application?
There are many options out there, but unfortunately, there is no one-size-fits-all choice. But this does mean that you can customize the cable gland according to your parameters. For this, you first need to consider a series of environmental and application factors.
The role of the environment
It doesn’t matter whether you work in aerospace, industry, marine, power and utilities, telecommunications or any other key industry. It is important to determine the core application environment of the cable connector. Ask yourself questions:
Do you use it indoors or outdoors?
Will it be located in a safe industrial area or in a hazardous or explosive environment?
What is the temperature, is it constant?
Is the surrounding moist or dusty?
Are there gases or corrosive substances nearby?
Your answers will help determine the specifications of cable glands and whether special protective plating or coatings are required.
Know your cable type
Different cables require different types of cable glands. For example, the requirements for armored cables are different from those for non-armored cables.
|Armored||An extra protective layer can prevent damage.
This can be single wire armor, braided armor, soft steel wire armor or double steel tape armor
|Areas threatened by mechanical damage|
|Unarmored||More basic than armor
There can be no seal, or a single external seal or a double external seal
|Fixed installation will not suffer the risk of mechanical damage|
