Overview of Cable Glands

Cable Glands are an essential part of your electrical installation: they guarantee a strong and reliable feed-thru for your cables and protect your installation from outside influences. The most important performance of Cable Glands is summarized as follows:

Protect your electrical equipment from outside influences such as dust and moisture.

Where the cable enters your device is where your device is most vulnerable: it creates an opening through which moisture and dust can enter. A cable gland seals the opening.

Provision of contingency relief

When the cable is subjected to some form of strain (" mechanical "strain or tension -- for example, due to cable being pulled), the cable may come loose from the installation, which may cause the installation device to no longer work properly. Cable crips provide strain relief and ensure no strain/tension is applied to the cable.

Different types of materials of Cable Glands

Cable Glands have a variety of types and materials to choose from. But when do you choose a material type? The following five types of Cable Glands will be highlighted in this blog:

Plastic insulated cable gland

Plastic Cable glands

Copper cable gland

Brass EMCCable glands

Stainless Steel Cable Glands

Plastic insulated cable gland

Plastic Cable Glands are the most basic Cable Glands in our products. Plastic Cable Glands are used for general occasions, there are no extreme conditions that affect Cable Glands, and special properties are not required. Plastic Cable Glands offer sufficient sealing capacity for most general purpose applications.

Plastic Cable glands

Plastic Cable Glands are available in three colours (light grey, silver grey and black) with thread lengths ranging from 8mm to 18mm. As the Cable Glands comply with different EC and IECEx certifications, this type of Cable Glands are certified for use in environments with explosion hazards.

Copper cable gland

Brass Cable Glands are made from galvanized brass. Therefore, they are stronger than plastic Cable Glands and have higher corrosion resistance and different types of strain and mechanical loads. However, they are not as sturdy as stainless steel Cable Glands. For applications where cable seals are exposed to different types of environmental effects, plastic cable seals are not enough, they are perfect.

Brass EMCCable glands

These brass Cable Glands are also made from zinc-plated nickel brass but, in addition, meet EMC standards. EMC stands for Electromagnetic compatibility. This means that the cable gland limits the level of interaction between electrical components within the electrical installation. Different electronic devices interact (which can lead to failures). EMC guidelines limit electromagnetic radiation to prevent this from happening.

Stainless Steel Cable Glands

Stainless steel Cable Glands, as expected, are made of stainless steel to ensure a long service life. They are even more resistant to corrosion than Cable Glands made of plastic or brass. This makes them particularly suitable for the heaviest applications, except in environments where there is a risk of explosion; Then always use Ex certified Cable Glands.
