They provide safety while minimizing risk in hazardous environments.
Cable glands serve multiple purposes in industrial cable installations. One function is to safeguard cables from external hazards.
Secure cable entry
Cable glands ensure that cables securely enter equipment or enclosures. They prevent the cable from moving, bending, or breaking. This ensures reliable performance in electrical systems.
Environmental protection
Many cable glands have an ingress protection rating. Thus, they shield against elements like moisture, dust, and chemicals. This protects the internal components of machinery or electrical systems from damage caused by these environmental factors. It also increases the lifespan of the equipment.
Pressure and explosion resistance
Some cable glands have special designs or certifications, like Ex e or Ex d. These glands are used in places where explosive atmospheres might occur. They help keep the pressure equalize and prevent explosions in dangerous settings. This function is vital for people working in the oil and gas, mining, or chemical industries.
Electrical grounding and separation
Cable glands help maintain electrical grounding when necessary. They also help separate different voltage cables. Proper grounding prevents electrical faults that can be dangerous. Meanwhile, cable separation minimizes interference between cables, thus ensuring each cable functions optimally.
Cable strain relief
Glands provide strain relief by transferring any mechanical stress from the cable to the equipment or enclosure. This prevents damage to the cable insulation. Thus, there is no risk of electrical shocks or system failures.
Vibration and fluctuation dampening
In industries with heavy machinery, cable vibrations can damage electrical systems. Some cable glands are designed to absorb or dampen these vibrations. They protect the internal wiring from damage in high-vibration environments. This is especially important in manufacturing and heavy machinery industries.
Some factors influence buyers' decision when choosing M20 cable glands for their clients. Here are some of them.
Material
Manufacturers make cable glands in different materials to suit various environments. These materials include brass, stainless steel, and plastic. Brass is strong, corrosion-resistant, and very affordable. Therefore, it is mostly used in the marine industry. On the other hand, stainless steel is very durable. It works best in industries where hygiene is a must, such as food and pharmaceuticals. Finally, nylon cable glands are lightweight. They are suitable for applications in telecommunication, automotive, and electronics.
Ingress Protection Rating
The IP rating of the gland determines the level of protection against solids and liquids. The ratings often used are IP66 and IP67. They are suitable for outdoor and industrial applications where moisture and dust are common. Therefore, choose a rating based on the client's industrial needs.
Type
There are two main categories of cable glands: non-armored and armored. Non-armored cable glands are used in applications where cables do not require additional mechanical protection. These applications include mild industrial environments. Conversely, manufacturers use armored cable glands in industries with high mechanical stress. These industries include construction and manufacturing. Therefore, select the type based on the client's environment.
Certification
Some clients will need cable glands to suit specific regulatory requirements. The most common certification is Ex d or Ex e. This certification makes the cable glands ideal for installations in hazardous areas.
Size
Buyers should get cable glands in various sizes. The sizes should correlate with the cable diameter. The size ensures the gland obtains a proper seal without being too tight or too loose. A proper sealing prevents moisture and contaminants from entering.
It is important for buyers to understand how their clients will use cable glands. Having this knowledge will help them when placing orders for cable glands.
Secure cables
Users should first strip the cable sheath to expose the wires. Then, secure the gland body onto the cable. After that, insert the cable into the equipment where it will be used. Next, tighten the gland nut onto the cable. This will create a tight seal around the cable.
Environmental sealing
The sealing keeps moisture and dust from entering the cable or equipment. Clients should use O-rings and grommets to help with this sealing. First, they should place an O-ring into the gland's groove after assembling it. This will make a barrier between water and dust. They should then install grommets between cables. Grommets are rubber plugs that fill empty spaces. They add extra protection where cables pass through openings or holes.
Adding protection
Aspirators or ventilators are devices that keep air moving through closed spaces. When users add ventilators to cable glands, they help prevent heat buildup. Too much heat can damage the cables and equipment. Buyers should look for cable glands with built-in air Ventilators. They help keep machines cool by circulating fresh air in and hot air out.
Strain relief
Some grommets have extra grooves. These are called strain relief ribs. Clients should use grommets with strain relief ribs for important applications. Users do not want cables to pull out or get damaged. Strain relief ribs help keep tension off cables. Thus, cables will stay safe even if moved around a lot.
Chemical protection
Often, cables are used near tanks or pipes. Sometimes, nasty chemicals leak from these. This can corrode or damage cables if not careful. Buyers should look for cable glands with chemical resistance. Plastic cable glands are resistant to corrosion. They are suitable for protecting cables from harmful chemicals.
There are several benefits M20 cable glands will give the clients who use them.
Better protection from the elements
Most cable glands have high IP ratings. Therefore, they offer superior sealing against water and dust. This rating keeps contaminants away from cables and electrical enclosures. Thus, internal components will be safer from damage and have a longer lifespan.
Comfortable installation
Many modern cable glands have designs that make them easier to install. For instance, they may have tools that are not needed to tighten or adjust them. Some even have features that allow for quick locking without instruments. These features will save the technicians time and effort during setup. Therefore, they will be more efficient when carrying out their work.
Versatility
Cable glands, such as metal ones, are adaptable. They suit various industries, such as manufacturing, marine, and chemical. Each of these industries has unique challenges. Metal cable glands are ideal for heavy-duty environments, while non-metallic ones suit lighter workspaces. Therefore, diverse industrial applications can widely use these glands.
