What are Cable glands?
A cable gland is the mechanical cable entry device that is attached to the end of electrical cables to provide security to any piece of equipment. They are commonly known as cable connectors, cable fittings, cable strain reliefs, or cable cord grips.
Cable glands are used for dismissing cables in harsh or hazardous areas where sealing and ingress protection is required. Cable glands are very important for electrical equipment and switch gears as they impose strain relief properties and can also be connected with the aluminum sheets or armor of cable.
As being a mechanical cable entry device, cable glands can be constructed by using metallic or non-metallic materials. They are considered as a necessary device across many industries where they are used in conjunction with cable and wiring that are further used in electrical instrumentation and automation systems. Cable glands are available in different sizes. Their primary role is to pass a tube, wire, or cable through an enclosure safely.
As we know that there are various types of cable glands present in the market but in today's discussion, we are going to focus our attention on Plastic cable gland types. We will first start with the definition of Plastic cable glands and then slowly dig down to the protection offered by plastic cable glands and then finally ending with the types and features of Plastic cable glands.
Plastic cable gland
Plastic cable glands are often used as a substitute for metal cable glands, this type of electrical cable glands offers corrosion-resistant entry of cable into electrical equipment. They help in securing the wires and cables by offering relief by keeping enclosure sealing requirements.
Types of protection offered by Plastic cable glands
The plastic cable gland provides Earthing, grounding, bonding, insulation, and stain relief.
These glands help in sealing cables that pass-through bulkheads or gland plates.
Plastic cable glands help in preventing external contaminations like dirt, dust, or fluid.
They stop cables from becoming pulled or twisted.
Types of Plastic cable glands
There are notably three types of Plastic cable glands as follows:
1. PG Thread Standard (PG)
Standard series – Ranging from 3mm to 44mm (depending on thread size)
Protection series - Ranging from 3mm to 18mm (depending on thread size)

2. Metric Thread Standard (M)
Standard series – Ranging from 3mm to 44mm (depending on thread size)
Protection series - Ranging from 3mm to 18mm (depending on thread size)
Colours – Light grey and black body colors
Includes Hex nut and washer
3. National Pipe Thread Standard (NPT)
Standard series – Ranging from 5mm to 25mm (depending on thread size)
Protection series - Ranging from 5mm to 18mm (depending on thread size)
Colours – Light grey and black body colors
Includes Hex nut and washer
These are the most common types of plastic cable glands available in the market. Plastic cable glands are taking on the market with their various useful applications.
This object's cable fittings, connectors, or glands might appear like a small thing to think about however, to get a suitable solution you sometimes need to ponder your thought into small but important things like plastic cable glands.
