What is a cable gland?

A cable gland is described as a mechanical cable entry module. They are used to secure the electrical cables that are used in the long-lasting connections, unlike household plugins that are disconnected quickly.

Most of the Industries that use electrical equipment to some extent make use of cable glands. Cable glands are varied in different types and sizes, and are used in different types of conditions and applications.

Where are cable glands used?

Answering the most common questions, why and where are cable glands used?

Types of cable glands.

There are various types of cable glands that are used in different equipment and environmental conditions. Most of the cable glands are categorised under different sectors like metals, plastic, armored, unarmoured, marine or fire protection glands, and other types. These cable glands are used depending on their sector's necessity. Some of the most common types of cable glands include-

A1/A2 Industrial cable gland.

This type of cable gland is designed to be used for unarmored cables. It is a Brass indoor and outdoor cable gland that is applicable for all types of unarmored wires. Generally, A1/A2 are plastic glands used to secure the outer jacket of the cable.

BW Industrial cable gland.

The BW Industrial type of cable gland is designed to be used for armored cables, plastic or rubber sheathed cables, additional grip is provided with the help of a lockring to the armor. The BW glands are also provided with integral earthing facilities.

CW Industrial cable gland.

Type CW cables are made of brass or stainless steel and used on plastic or rubber sheathed cables with armor. The CW type of cable gland is designed to serve the same purpose as the BW Industrial cable gland.

E1 W/F Industrial cable gland.

Cables with armor and plastic or rubber outer sheathed use E1 W/F cable gland. The E1 W/F type of cable gland is mostly suitable for climatic conditions, they are weatherproof and waterproof. They can be used in indoor as well as outdoor conditions.

Single compression and Double compression cable glands.

The single compression cable glands are mostly used in corrosive conditions as they are weatherproof. The single compression cable glands come with the B. S. C. thread. A single compression type of cable gland is used for indoor conditions for all types of unarmored wires.

The Double compression cable gland is a brass outdoor cable gland that is suitable for armored cables and unarmored cables. They are also used in corrosive conditions and are weatherproof and flameproof. The Double compression glands are also supplied with the B. S. C. thread.

These are some of the types of electrical cable glands that are used in protection of the cables and electrical equipment. The perfect type of gland is needed to be used for suitable cable wires, according to its type and conditions. For eg, a type of armored cable gland should be used for the described cables.

There are four principal types of cable gland:

• Single compression - typically used within buildings and for smaller installations
• Double compression - mainly used in power plants and factories where stronger seals are required. These glands feature double sealing and the application of double compression at the cable core and on the outer sheathing or armour
• Flexible hose - used in higher temperature locations
• PVC - typically used for control cables attached to instrumentation

Both single and double-compression cable glands are further divided into three additional types:

• Light duty
• Weatherproof
• Flameproof

Threading (the mechanical grooves applied to the nuts or attachments) also varies from gland to gland. Look for the following standards, each with different uses:

• ISO metric thread - a widely used international standard for screw threading
• National pipe thread - a US standard used for threaded pipes and pipe fittings

When choosing the correct cable gland, look for the following criteria:

• The minimum and maximum operating temperature
• The pressure rating - i.e. the maximum pressure the cable will tolerate before leaking or breaking
• The size and type of cabling it is compatible with, something principally determined by the diameter of the gland. Most cable glands are available in a range of diameters to match
• The size and type of mounting featured - i.e. the head which seals the cable into place. These are normally threaded

Armoured Cable Glands

Armoured cable glands are designed for use with steel-wired armoured (SWA) cables, also known simply as armoured cable. This is the standard for underground and wall cabling installations. The steel mesh protects the cable from damage.

Waterproof Cable Glands

Waterproof cable glands typically offer IP68 waterproofing, meaning that they can resist immersion in water one metre or more in depth. The International Protection (IP) standard is a widely used marker of resistance to water, dust and other contaminants.

Metal Cable Glands

Metal cable glands made from stainless steel, aluminium, and brass offer a range of benefits:

• Stainless steel is a good choice for corrosion and pressure resistance
• Aluminium is flexible, resistant to rust and also conducts heat and electricity well
• Brass is a time-honoured choice offering strength and resistance to magnetism and deformation at both high and low temperatures. It also offers good electrical conductivity. It is widely used in the construction industry and industrial settings

Six types of brass cable glands are available:

1. Indoor - a versatile design good for different types of cable, including armoured, plastic and rubber-sheathed
2. Outdoor - these can be used with both plastic or rubber sheathed and unsheathed cables
3. Straightening - these are used with both rubber sheathed and unsheathed cables and can be used in both indoor and outdoor settings
4. Weatherproof - these cable glands are used with both plastic or rubber sheathed cables and are built to be robust and provide a strong seal. A variation of this gland is specifically designed for maximum resistance to water
5. Threaded - these are custom-made glands used for certain industrial applications
6. Industrial - this gland is principally used with plastic or rubber sheathed and armoured cabling

Rubber Cable Glands

The watertight seals in some types of cable glands are made from synthetic rubber. Chloroprene is used to make o-rings, a circular gasket that forms an efficient seal. Neoprene, meanwhile, is more typically used for washers - i.e. flat sealant rings.
