Plastic Cable Glands: Types And Usages

Plastic Cable Glands - Jigo India

The cable gland is an essential component of electric infrastructure and panel assemblies where wires must be attached and protected.

It is possible to find cable glands in almost any industry that uses electrical equipment of some kind.

In layman’s terms, cable glands are mechanical cable entry modules used to secure electrical cables to equipment. Cable glands are used mainly for the following purposes:

  • Connector protection: Cable glands seal the outer cable sheath, protecting the electrical enclosure and wiring from dust, dirt, moisture, and other factors that may compromise its performance.
  • Cable tension relief: The cable gland secures the cable to the installation and locks it into place. It provides resistance to twisting and pulling forces so that the cable does not break.

The main difference between cable gland designs is their material. They are commonly made of the following materials:

  • Metals: These include stainless steel, aluminium, and nickel-plated brass. Stability, durability, electrical and thermal conductivity are some of the critical benefits of this material. IT, medical and chemical industries are some examples of potential applications.
  • Plastics:  Plastic cable glands typically have a claw and seal design and are made of polyamide or nylon. They possess high adaptability and resistance to various corrosive elements, saltwater, weak acids, and grease, making them an excellent choice for multiple industries such as telecommunications, marine, and flex cable applications.

Today, our blog will feature a few of the most popular plastic cable glands available based on thread type.

Let’s begin right away.

  1. Metric Connection Thread: Installing and assembling these plastic cable glands is relatively straightforward. They are designed to be used in general applications such as electrical and mechanical equipment, control, automation, and manufacturing equipment. Besides having an integrated anchorage, they feature an extensive sealing and clamping range.
  2. PG Connection Thread: These plastic glands can withstand temperatures as low as -20 °C and as high as 100 °C. The trapezoidal thread ensures a tight and permanent fit of the dome nut, making it gas and watertight.
  3. NPT (National Pipe Thread) – A seal and clamp system of the conical NPT thread allows the cord connector to tighten in a circular pattern on the sealing ring to provide superior strain relief without twisting or damaging the cable. Almost every setup with moving or rotating parts needs this safety feature to operate correctly.

Final Words

It can be challenging to determine what type of cable gland to choose for a specific application and which features to look for since there are so many different cable connector features and designs to choose from.

Cable glands serve as an essential safety feature whether you work in the aviation, marine, power, telecommunication, or industrial sectors.

We hope this blog on the different types of plastic cable glands has given you valuable insight and provided you with a better understanding of their functionality.

Cable glands are an important part of your electrical installation. They are connectors used to seal the ends of cables and secure them to plugs, terminals, enclosures, or electrical equipment of various kinds. They are also commonly known as cable fittings, cord grips, etc. They can protect sensitive electrical wiring from external influences such as moisture, contamination, corrosion, and even flammable gas.

Cable glands are a must-have in harsh or hazardous environments where sealing and ingress protection must prevent electrical sparks of flames. They can also be used to seal cables that pass through bulkheads or gland plates.

As mechanical cable entry devices, cable glands can be constructed from metallic or non-metallic materials. Some of the materials include Plastic, Nylon, Stainless Steel, Aluminium, Nickel, Brass, Synthetic rubbers, etc.

Metal cable glands are highly favored in chemical, technology, and other industries that demand high chemical and mechanical stability.

Nonetheless, the objective of this blog is to educate you on plastic cable glands and why you should use them.

What is a plastic Cable Gland?

The body of the Plastic Cable gland is manufactured from polyamide, and the sealing is made of Neoprene.

A plastic cable gland is used as a sealing and termination device to ensure that the characteristics of the enclosure through which the cable enters are maintained. They effectively fix cables in place and prevent them from being twisted or accidentally pulled out to ensure a secure connection and continuous performance.

Plastic Cable Glands have universal purposes and can be used in all kinds of electrical power, control, data, instrumentation, and telecommunications cables. They are ideal in situations where no extreme conditions affect the cable gland and where no exceptional properties are required.

What are the benefits of using Plastic Cable Glands?

High Impact Resistance: Plastic Cable glands offer corrosion-resistant cable entry into electrical equipment since they are immune to salt water, grease, and other weak acids. Additionally, they can withstand distortion and vibration, making them ideal for use in petrochemical industries.

Cost-effective: Plastic is reasonably cheaper than Steel, Aluminum, and other metals used to make cable glands. Hence, plastic cable glands are an economical choice.

Offers flexibility of choice: Plastic cable glands come in a wide range of claw and seal designs, making them extremely adaptable to a wide range of applications.

Intrinsic Insulator: Plastic is a poor conductor of heat and electricity. A feature like this is especially important in marine environments and high-temperature settings, posing a risk of damage due to electrical shortages or explosions.

Bending Protection: Plastic cable glands are lightweight and eliminate cable bending, restricting movements around the device. The spiral shape helps prevent conductor breakage and reduces the likelihood of failure.

Plastic Cable Glands

Plastic Cable glands are designed to permit, the entry of cable wires into electrical equipment or components which provides earthing, grounding, bonding, insulation, sealing, retention, and strain relief. It also provides mechanical support for cables. They are often placed in hazardous or harsh surroundings where they need to contain electrical sparks of flames or resists outside contaminants such as dirt, fluids, and dust. Along with this, their job is to prevent cables from twisting to ensure secure connectivity with continual performance.
