Can EMC Gland PG Thread be used with armored cables?

As a reliable supplier of EMC Gland PG Thread, I often encounter questions from customers regarding the compatibility of our products with armored cables. In this blog post, I'll delve into the details to provide a comprehensive answer to this frequently asked question.

First, let's understand what EMC Gland PG Thread and armored cables are. EMC (Electromagnetic Compatibility) Gland PG Thread is a type of cable gland that is designed to ensure a secure and reliable connection between the cable and the equipment. The PG (Panzergewinde) thread is a standard thread type commonly used in Europe for cable glands. It offers a high level of mechanical strength and sealing performance, which is crucial for protecting cables from environmental factors such as dust, moisture, and electromagnetic interference.

On the other hand, armored cables are cables that are protected by a layer of armor, typically made of steel wires or tapes. This armor provides additional mechanical protection to the cable, making it suitable for use in harsh environments where the cable may be exposed to physical damage, such as in industrial plants, construction sites, and outdoor installations.

Now, the question is whether EMC Gland PG Thread can be used with armored cables. The answer is yes, in most cases, EMC Gland PG Thread can be used effectively with armored cables. Here are several reasons and considerations to support this:

1. Mechanical Compatibility:
   • The PG thread of the EMC gland is designed to provide a tight and secure fit. Armored cables usually have a relatively rigid outer structure due to the armor layer. The mechanical strength of the PG thread allows it to grip the armored cable firmly, preventing the cable from pulling out or moving within the gland. This is essential for maintaining a stable connection, especially in applications where the cable may be subject to vibrations or mechanical stress.
2. Sealing Performance:
   • EMC glands are known for their excellent sealing capabilities. When used with armored cables, the gland can create a seal around the cable, protecting it from moisture, dust, and other contaminants. This is particularly important for armored cables, as the armor itself may not provide complete protection against these elements. A good seal helps to prevent corrosion of the cable conductors and insulation, thereby extending the lifespan of the cable.
3. EMC Protection:
   • One of the key functions of EMC glands is to provide electromagnetic shielding. Armored cables also have some level of electromagnetic shielding due to the conductive nature of the armor. When an EMC Gland PG Thread is used with an armored cable, the gland can enhance the overall electromagnetic shielding effectiveness. It helps to prevent electromagnetic interference (EMI) from entering or leaving the cable, which is crucial for maintaining the proper functioning of sensitive electronic equipment connected to the cable.

However, there are also some factors that need to be considered when using EMC Gland PG Thread with armored cables:

1. Cable Size:
   • It is essential to select the correct size of EMC gland for the armored cable. The PG thread size of the gland should match the outer diameter of the armored cable. If the gland is too small, it may not be able to accommodate the cable properly, leading to a poor fit and reduced sealing performance. On the other hand, if the gland is too large, it may not provide a secure grip on the cable, increasing the risk of the cable moving or being damaged.
2. Armor Type and Thickness:
   • Different types of armored cables have different armor designs and thicknesses. Some armored cables may have a thin and flexible armor, while others may have a thick and rigid one. The EMC gland should be able to handle the specific type and thickness of the armor. For example, glands with a wider clamping range may be more suitable for cables with thicker armor. It is important to choose a gland that can be adjusted to fit the particular armored cable being used.
3. Installation Method:
   • Proper installation of the EMC Gland PG Thread is crucial when using it with armored cables. The installation process should follow the manufacturer's instructions carefully. This may include steps such as stripping the outer sheath of the armored cable, preparing the armor for connection to the gland, and tightening the gland to the correct torque. Incorrect installation can lead to issues such as poor sealing, reduced mechanical grip, and compromised EMC performance.

In addition to the above considerations, our company offers a variety of EMC Gland PG Thread products that are specifically designed for use with armored cables. We also provide other related products such as Nickel Plated Brass Gland, which offers enhanced corrosion resistance, and Double Compression Cable Gland, which provides an extra level of mechanical protection. For applications where metric and PG threads need to be converted, we also have Brass Metric To PG Reducer available.
