Features of a Cable Gland
Cable Glands are specifically designed to withstand your connections with the harsh environment.
cable gland prevents from sudden connections accidents and lowers risk in the area. The following are the key features in using cable glands.
A Cable Gland provides several features:
Cable Glands are specifically designed to prohibit the ignition of flammable mixture in the connection. The glands protect the connection from sudden sparks and minimize danger.
- Impact resistance
Each cable gland should pass the resistance test on external impact. It should be the ideal tool that passed the ingress protection rate and must provide resistance from various friction and vibrations even under extreme temperature.
- Explosion proof
Cable gland provides protection against possible explosion from your connections. It does not only protect your cables from external contaminations that could cause possible explosions but also insulates your connection to limit the possibility of explosions and accidents with the connections.
- EMI (Electromagnetic) shielding
The EMI or electromagnetic interference is common transmission problems from cables and electrical appliances. In using the right cable gland, it provides EMI shielding of your connection.
It prevents interferences from emitting on neighboring cables that could cost connection failure.
One of the main features of a cable gland is to have a weather-proof capability. This ensures its purpose to use for cable connections that requires protection from weather that promotes corrosion.
It protects from exposure in harsh weather environment that might cause corrosion.
- Environmental sealant
A cable gland should effectively be resistant to various chemical damage, oil exposure, and various dust or gases. A cable gland should have the proper sealant that won’t allow these environmental from entering the connection and possibly deteriorating the cables.
- Strain relief
A cable gland’s main function is to seal and protect your cable connection. It shouldn’t cost strain on the cable and should freely hold the cables without causing any damage to your cables.
It should protect your wirings from the mechanical force being applied to the exterior of the cable for it might cause a connection failure.
What are the Common Applications of a Cable Gland?
Cable Gland is a connector that can be used in various applications. Here are the following fields where cable glands can be used:

How Does a Cable Gland Work?
A cable gland is a connector of a cable to an electric source. It is divided into different applications depending on where it will be used or what type of cable it is going to connect.
A Cable gland can be used for two purposes:
1.) General Industrial applications
2.) Hazardous applications
The former are your common applications for electrical connections like ethernet cable, household wiring and others. The latter is used for protection against high temperatures and/or risk of explosions. cable gland are connections used to extreme environment and explosive atmosphere.
According to the regulation of DSEAR 2002 (Dangerous Substances and Explosive Atmospheres Regulations), these extreme environment and explosive atmosphere are work places with dangerous substance with the air.
It could be gases, vapors, mist, gases, dust that can cause possible ignition. These are work places that handle fine organic dusts from grain flour or wood.
This also include factories of paints and other chemicals where a single spark from an electrical current and the like may cause an explosion or flame.
It allows electricity to pass through the cable and the power source and ensures the safety of your connection and anyone nearby.
It seals your cable to prevent it from slipping off from your connections, grounding the wire and insulating your cables, preventing electrical seepage.
Guide for Choosing the Right Cable Gland
In choosing the right cable gland, it’s not enough just to know neither the name nor the color of the gland. There are several things to consider before buying one. This guide will help you know how to choose the right cable gland for your desired installation:
In installation of cable glands, it doesn’t matter what application it is for but rather the environment where it is going to be installed. You can use these questions as a guide:
- Are you using it indoors or outdoors?
- Will it be installed in an industrial zone or a hazardous workplace?
- What is the working temperature, is it constant or high temperature?
- Is the environment damp or dusty?
- Are there any corrosive materials nearby?
- Is it exposed to different gases or weathering?
- Is the pressure rating high enough for your application needs?
- Do you have a sufficient cable diameter?
- Does it comply with national or international codes of practice?
Answering these questions will help in limiting the list of cable glands to what you really need. It ensures the safety of your installation.
It is vital that you check on the supplier you will buy it from because the rating system is a top factor – the Ingress Protection or IP marking should be highly considered. The rates marking usually go up to IP68 and IP69K.
- CABLE TYPE
Cable glands have its own specificity in terms of the type of cable you are going to use. Cables have two types: 1.) Armored cable & 2.) Unarmored cable.
An Armored cable has an extra layer of protection that prevents damage to the wirings. It may be a single wire armor, pliable wire armor or braided armor. They each serve a purpose depending on where it is going to be installed. For Unarmored cable, there is no seal but just your basic cable.
The reason why you should consider this is because armored cable has a different diameter in terms of inner bedding lead covering. This will help you identify what cable gland is suitable for each cable.
Other than that, it is also important to consider the following for both types of cables:
- Cable diameter
- Construction Size
- Cable material
ARMORED CABLE GLAND
The Armored Cable Gland is the type of gland compatible for armored cable installation. It is commonly used for underground systems and power installation.
DIFVAN cable glands are compatible with indoor and outdoor applications. It is also compatible for hazardous environment applications and has an ingress protection of IP65 and IP68. It can also accommodate various types of armored cables and available in various sizes.
pg cable gland and m cable gland maintains earth continuity and ensures sealing grip against external contaminant and internal explosion through its flameproof feature. It also ensures strain relief for the cables.
TYPES OF CABLE GLANDS BASED ON THE ARMORED CABLE USED:
- Steel Wire Armored Cable Glands (SWA)
The SWA Cable glands is a type of cable gland that accommodates the SWA cables.
It is a cable gland that is suitable for all SWA cable suitable for indoor and outdoor applications. It provides an IP66 environmental seal that both protects the cable’s inner and other sheaths.
- Aluminum Wire Armored Cable Glands (AWA)
The AWA wire armored cable glands are those that accommodate AWA wires. It is compatible for indoor and outdoor installation that insulates the cables from weather corrosion and various environmental contaminant that might cause a connection. It is available with an ingress protection of IP66 and can be used for heavy-duty connections.
ARMORED CABLE GLAND INSTALLATION PROCEDURE
A Cable Gland can accommodate two types of armored cable- AWA and SWA cable. They are the standard cables for underground installation that provides dual protection wiring connection than a typical cable.
The difference between a regular cable and an armored cable is its conductor cores that range from 2 to 4 cores. Some manufacturers even provide more than that. It is the ideal cable for industrial applications and heavy-duty wiring installation.
Here is an installation procedure of a SWA cable:
(*Note: Before installation makes sure that the power source is switched off and cannot be accidentally turned back on. This installation information is for home installation, if unsure of what to do, it is more suitable to call an electrician to avoid unnecessary accidents and termination failure.)
Step 1. Prepare your materials
In installing your armored cable gland, make sure that your cutting tools, splicing tool, wrenches, and cable gland are already prepared.
Avoid using tools unfit for cable cutting and splicing. This will avoid any potential accidents and installation errors.
If necessary, wear safety goggles if the workplace is exposed to dust or any harmful components. You can use gloves to avoid skin irritation from possible components from the gland.
Step 2. Cut the cables
Cut the cable with a wire cutter or a hacksaw depending on the size of the cable being installed.
Step 3. Prepare your Gland
Each type of cable gland has different parts. For example, an external gland has the following parts: 1.) Nut, 2.) earth tag, 3.) nozzle, 4.) collar, 5.) collar nut, 6.) nut with a rubber seal, and 7.) cover.
In preparing your cable, make sure to place it on a safe and clean place. Do not leave it on the floor or on dirt that could possibly contaminate the gland.
Make sure that it is clean did not come in any contaminants and moisture. This is to avoid connection failure. Other than that, do not lose the other parts because the sealing grip won’t work.
Step 4. Insert the needed parts.
Drill a hole that will allow the nozzle of the cable gland to fit through. In this installation, it will be fastened on a waterproof adaptable box. After drilling a hole, insert the earth tag followed by the nozzle through the hole and screw the nut inside the box to hold the nozzle in place. Use two spanners or wrench each holding the nut and the nozzle and turn them tightly. (Do not overtighten the gland)
Afterwards, cut the cover of the gland and insert the cable followed by the rubber sealing ring, nozzle nut, and the collar onto the cable.
Step 5. Cut the outer protective sheath and galvanized wire
Cut the other protective sheath of the cable to expose the galvanized steel wires. Gently spread the wires and cut it on a length enough to insert in the gland.
The exposed wire should look like this. Be extra careful in cutting the galvanized wires. You have to use appropriate cutting tools in doing so especially on thicker SWA cables.
Step 6. Insert the parts
Simply push up the wires of the inner core through the nozzle, making the galvanized wires to flare outside. Push the collar over the wire to the nozzle and use two spanners to tightly connect the parts.
Finally, slide up the cover over the gland for extra sealant.
Step 7. Inner insulation
After connecting your glands, you can now strip your inner insulation. You can just simply use a cutting tool to cut through the cover but be careful not to damage the inner cores. Afterwards, you can now splice your inner wires to connect on various connectors.
- MATERIAL TYPE
Cable glands have three main types:
1.) Metal (Brass, Aluminum, Stainless Steel) – This type of cable gland is used for applications in technology, chemical industry and other areas that has a high demand in tools that have high durability from wet and rigid environment.
2.) Plastic – The Plastic Cable gland is an adaptable gland that can be used in a wide range of application. It is also specifically resistant to salt water, weak acids, grease and others.
3.) Nylon– Nylon Cable Glands however are designed to have a UV resistance and a higher rate of resistance relief.
- RATINGS AND STANDARDS
Cable glands are designed to ensure the safety of the user and the connection. That is why it has an Ingress Protection Marking or IP rates in every type of cable glands.
These ratings are based on its compatibility to the environment to where it is going to be installed. The higher rates, the more compatible it is on hazardous environment.
Most cable glands are also produced based on the European Standard or EN50262 that tells which cable gland is suitable for a certain connection and its compatibility.
When you finally have the answers to those questions and about to buy your cable gland, make sure to check the products specification. Every manufacturer has different specifications of their cable gland.
For example, the Cable Gland Lapp of the Lapp Group Company has its own specifications. This will ensure the safety of your connection and will help you correctly choose the cable glands based on your needs.
