What Is Long Thread Cable Gland

Strain relief cable glands with long thread length also known as spiral brass cable glands or flex-protect cable glands offer added protection to the cable at its point of entry. The spiral head distributes strain over a larger area, it avoiding damage that can result through repeated bending of the cord. These glands are made of brass and have an internal compression claw ring, which assures a liquid-tight and tug-proof grip on the cable. Cable gland means the gland designed in metric thread longer than normal size for special applications, the hole dimension size in 22mm. Long thread cable gland normally required for the enclosure much thicker than normal, the length of normal size cable gland is not enough to fix with the lock nut, in this case, the long thread cable gland will be customized to be designed to match it.

How Do Long Thread Cable Gland Work?

Cable glands are made by combining a central enclosure or body through which cabling can pass with several attachments. These are typically a lock (or check) nut, washers, seal, attachment claw or cone, and a sealing (or compression) nut. Some models also feature two-part enclosures, tags for electrical earthing, PVC shrouding (insulation) or neoprene (rubber) sealing.

The size, arrangement and design of these vary according to the type of cable gland. Cable glands have the following principal functions: Fixing cables in place and preventing them from being twisted or accidentally pulled out. Providing an airtight seal to keep out dust, dirt, water and moisture - a key function with electrical equipment.

Fortifying the cable against strain. Protecting the vulnerable end of the cable from damage. Some also help to earth electrical cables and cut the risk of shocks and electrocution. Cable glands are made from a range of materials, including: PVC (polyvinyl chloride) - a flexible and non-reactive plastic. PTFE (polytetrafluoroethylene) - this plastic is highly resistant to chemicals and similar substances. Nylon - a tough, multipurpose choice with strong resistance to pressure.

Installation and Usage of Long Thread Cable Gland

Before you can begin to install a cable gland you need to choose the right type. Consider the material, IP rating, thread type and temperature range. Always make sure that you choose the right equipment for your application and you follow the manufacturer’s instructions.
To provide a safe and dependable connection, installing cable glands includes many steps. Here is the process of installing cable glands:

Choose the right cable gland

Choose a cable gland that matches the cable diameter and is suitable for the specific application and environmental conditions. Then, remove any protective caps or inserts from the cable gland.

Prepare the cable

Strip the outer sheathing of the cable to expose the conductors. The length of the stripped portion should be sufficient to accommodate the cable gland and provide proper engagement.

Insert the cable into the cable gland

Insert the stripped end of the cable through the cable gland’s entry thread or opening. Then, ensure that the cable is fully inserted, allowing the conductors to extend beyond the sealing area.

Position the sealing elements

Arrange the sealing elements, such as rubber or plastic seals, around the cable in the cable gland. These seals provide the necessary moisture and dust protection.

Tighten the locknut

Thread the lock nut onto the cable gland’s body and tighten it securely by hand. Avoid over-tightening, as it can damage the cable or the gland.

Final tightening

Use appropriate tools, such as wrenches or spanners, to further tighten the locknut and ensure a proper seal. Follow the manufacturer’s instructions regarding torque specifications.

Check for proper installation

First, verify that the cable is securely held within the cable gland without any excessive strain or tension. Then, ensure that the sealing elements are compressed evenly around the cable, providing a tight seal. Lastly, inspect for any visible gaps or misalignment that may compromise the effectiveness of the seal.

Test the connection

Conduct appropriate tests to ensure that the cable gland and connection meet the desired electrical and safety standards. This may include insulation resistance testing or continuity checks.

Structure of Long Thread Cable Gland

Prior to the selection of cable glands, users shall have a notion of cable glands’ basic structure. Main components of cable glands include: The gland body is made from various materials such as plastic, brass, stainless steel. This component constitutes the outer sheath, ensuring the structural integrity and serving as a conduit for cables to pass through.

Cap nut is basically made of the same materials as the main body, threads onto the body, and secures the cables in place. The design of the nut consists of a series of ridges or teeth that grip the outer shell of the cable, preventing the cable from slipping out. The threaded connection between the nut and body provides a secure cover for the cables inside.

Moulded seal is made from elastic material such as rubber or silicon. The main function of this part is to create a tight sealing layer, preventing the penetration of moisture and dust. Depending on the level of protection required, the part can be made from materials that demonstrate enhanced characteristics in extreme temperatures and environments.

Clamping seal insert plays the role of securing cables, alleviating the strain and preventing cables from being pulled or twisted.
Entry thread: is the point where cables are inserted into the cable glands. The choice of thread size must be compatible with the diameter and types of cables used. In some cable gland configurations, there might be additional locknut (extremely useful for moving applications), O-ring (enhancing the tight sealing ability).

Quality Control in Long Thread Cable Gland Manufacturing

Quality control is a critical aspect of cable gland manufacturing. It ensures that the products meet the required specifications and are safe for use. It involves various checks and tests at different stages of the production process.

At the initial stage, the raw materials are inspected for quality and consistency. This includes checking the material composition, dimensions, and surface finish. Any defects or inconsistencies can affect the performance of the cable gland, so it’s crucial to detect and address them early.

During the machining process, the components are checked for accuracy and precision. This involves measuring the dimensions and tolerances using precision instruments such as micrometers and calipers. The components are also inspected for surface defects such as scratches or burrs.

After assembly, the cable gland is tested for electrical and mechanical performance. This includes testing the electrical resistance and insulation properties, and checking the strength and durability of the assembly. The cable gland is also tested for environmental resistance, such as corrosion resistance and water-tightness.

What Factors To Consider While Choosing A Right Long Thread Cable Gland Size

When selecting the right cable gland size, several factors should be taken into consideration to ensure optimal performance and safety.

Cable diameter

Measure the outer diameter of the cable accurately to determine the appropriate gland size that provides a snug fit without excessive compression or strain.

Cable material

Different cable materials have varying flexibility and thickness, affecting the required gland size. Consider the characteristics of cable materials to select a compatible size.

Installation method

Consider the installation process and available tools. Ensure that the chosen gland size aligns with the installation method, whether it’s thread or compression-based.

Sealing requirements

Determine the level of ingress protection needed. Ensure that the selected gland size offers adequate sealing to prevent the entry of dust, water, or other contaminants.

Cable retention

Check the weight and movement of the cable. Choose a cable gland size that provides sufficient grip and strain relief to keep the cable securely in place.
