The armored cable gland is a special type of gland used for introducing cables with a metal layer (armored) into panels and equipment. Unlike simple models, this gland has two clamping parts: one grips the armor wires of the cable, and the other secures the cable itself. This feature ensures that in heavy industries such as petrochemical, mining, and marine facilities, the cable is both firmly held and the wires are bonded to the body. This type of gland and the explosion-proof cable gland are among the best-selling cable glands for sensitive and high-risk industries.

The armored cable gland is one of the vital components in various industries, especially in industrial and high-risk environments. Due to its specific features, such as resistance to impact, water, and dust, this product is considered an ideal choice for infrastructure and industrial projects. In this section, we will examine more details of this product and its applications in various industries.
One of the most important factors in the efficiency of the armored cable gland is the type of materials used in its manufacture. Typically, these glands are manufactured from resistant metals such as brass or stainless steel, giving them the ability to withstand harsh conditions and corrosive environments. This resistance becomes particularly more important in the oil and gas industries, chemical industries, and marine environments, where equipment is heavily exposed to environmental damage.
Using armored cable glands not only contributes to greater safety but can also significantly reduce maintenance costs. Due to their high durability and resistance to environmental factors, this type of gland reduces the need for frequent replacement and repairs. In addition, the correct installation of these glands can prevent damage to cables and, as a result, also increase the service life of the cables.
One of the main applications of armored cable glands is their use in underground projects such as tunnels and subways. In these environments, cables are heavily exposed to impact and pressure, and the use of armored glands can significantly increase the safety of the cables. This feature is especially important in large urban projects that require long-distance cabling deep underground.
Armored cable glands play an important role in improving the performance of electrical systems. By preventing moisture and dust from entering the cables, these glands can prevent the occurrence of short circuits and possible failures. This matter is especially important in sensitive electrical systems such as industrial automation and electrical controls.
For better efficiency of armored cable glands, their correct installation and maintenance are of particular importance. First, it must be ensured that the gland is correctly selected and suitable for the type of cable. Also, its correct installation must be such that excessive pressure is not applied to the cable. After installation, periodic inspections and necessary tests to ensure proper function and the absence of failure are among the measures that should not be overlooked.
For the armored cable gland to be able to connect electrical cables to other equipment and devices at the highest level of safety, it is necessary for it to have a series of standard internal parts and components to support the electrical cables and create a safe connection. Each of these small parts follows a specific function and must definitely be used in its correct area. To become fully familiar with the components of the armored cable gland, please refer to the following list.
Sealing Nut
The sealing nut of the armored brass cable gland is a small, hexagonal component. This hex nut is primarily responsible for connecting the cable to the gland. It is through the use of this nut that cables remain in place with high strength, resistance, and long-term stability. In terms of structural material, it is usually made from rustproof and fully corrosion-resistant stainless steel. It can also be made from metals such as high-density aluminum and nickel- and chrome-plated brass.
Seal
The sealing component is a type of lock nut that has an elastic polymer structure. This part can precisely prevent the possible rotation of the metal nut. The main diameter of this lock nut is smaller than the metal nut, so it easily fits inside it and, by creating structural friction, prevents the main nut from twisting. Therefore, in the long term, with the presence of this plastic component, the main nut will not become loose.
Armored Cable Gland Body
The body of the armored cable gland has larger dimensions compared to other parts and components of the gland, and other smaller parts such as washers are placed at its end section. With the full support of the main body for the electrical cables, we will no longer witness the accidental detachment of the cable from the electronic equipment.
The lock nut is a small cylinder with relatively delicate dimensions, used to engage the cable with the main components of the gland. The lock nut can provide a completely sealed mechanical system to support the electrical cable. Structurally, it has a high similarity to an O-ring and can, in some ways, prevent the cable from being pulled out.
Armored Clamping Cone
This component, by applying slight pressure on the cable body, can prevent the cables from slipping and being pulled out of the gland. As you can see, this part has two circular cross-sections with different dimensions, through which the cable enters from one side and exits from the other.
Compression Nut
This relatively long cylindrical component also provides all-around support for the cables, in such a way that by applying controlled forces on the cable and creating slight friction, it can secure the cable inside the gland.
Armored cable glands have very wide applications in various industries. For this reason, their use cannot be limited to small panels and equipment. Therefore, some of the industries and organizations that abundantly use these parts include the following:
Cable glands are generally designed and manufactured from several different materials. This intelligent measure can result in budget management as well as a reduction in the product price. In environments where there is no physical stress, you do not need to use glands with high hardness levels. For this reason, you can use types with a weaker structure. However, in general, cable glands are made from materials such as plastic or compressed polymers, brass, galvanized stainless steel, and also stainless steel. These gland materials are classified in order from low to high hardness levels. Therefore, in work environments where, in addition to high humidity, there are physical stresses such as the application of force and pressure, it is better to use glands with a stronger structure.
