Why Do You Need Brass Cable Glands For Switch Gears And Electricals Equipment?

A brass cable gland is the 'mechanical cable entry device' which connects to the terminal of electrical cables and secures them to any piece of apparatus. They are also known as cable connectors, cable fittings, cord grips, or cable strain reliefs.

Cable glands are vital for ending cables in harsh or venturesome areas where protection and ingress protection is required. These units are necessary for electrical instrumentality and switch gears as they offer strain relief and can even attach to the aluminum sheath or armor of the cable.

As mechanical cable entry devices, metallic or non-metallic materials make up cable glands. Brass cable glands are necessary across many industries that use these in conjunction with cable and wiring used in electrical instrumentation and automation systems. They find use on the cable of all on the market sizes and sorts. Its primary role is to pass a tube wire or cable through an enclosure. However, they also find uses in protecting electrical parts from flames which may occur in hazardous areas.

Purpose of cable glands:

As mechanical fittings, they are components of the electrical installation. They strengthen the attachments of cables with the electrical instrumentality to which the cable is connected. They protect:

·       The entrance out of the instrumentality from mud

·       From being twisted at the connecting edge to the instrument

Brass cable glands are for all sorts of power, control, instrumentation, data, and telecommunications cables. As a protection and termination device, they ensure that the characteristics of the enclosure that the cable enters are adequately maintained.

What is the need for Cable Glands?

For cable management, the cable gland plays multiple roles in the protection of the cable's attachments. 

What proper protection do they offer?

Cable glands provide fastening, grounding, bonding, insulation, and strain relief.

They seal cables that face up to bulkheads or gland plates. They can forestall external contaminants like dirt, dust, or fluid and embed an electrical spark or a flame.

 Stop the cable from becoming forced or twisted among the cable gland's remit.

Working of cable glands

Brass cable glands primarily work as a protection device that protects the enclosures on electrical instrumentality. The gland is a seal to the entry edge, stopping impurities from outside to cause any damage to the electrical system and the cable.

Environmental contaminants like dirt, fluid, or water cause damage to the cable joints and may cause disconnection from the electrical parts. Therefore, cable glands stop cables from being stretched and twisted out of the machine.

Cable glands usage:

● Earth continuity in an armored cable. If the cable organ encompasses a metallic construction that needs testing to check its ability to sustain any sturdy short-circuits or fault currents. 

● On a cable, it acts as a holding force guaranteeing only an adequate resistance level is allowed.

● Provides environmental protection by securing the outer cable sheath by consoling that mud or water can reach the enclosed area.

● It offers additional levels of protection to parts of installations where there is a necessity for excellent ingress protection.

 ● Provides additional environmental protection at the cable entry edge that maintains the ingress protection rating of the enclosure.

There are multiple decisions to decide on cable glands as they are factory-made and support the environments where they reside.

Points to keep in mind while choosing Cable Glands:

While choosing cable glands, you should consider following factors:

● Is it on the brink of being used within or outdoors?

● Is it going to be used in an explosive or venturesome atmosphere or a secure industrial zone?

● Will it be placed in an area where the surroundings are soiled or damp?

● Is there any presence of corrosive materials or gases nearby?

● Is it applicable for the dimensions and kind of cable used?

Types of Cable Glands: 

There are various types of cable glands. Few of them include:

●   Single compression - For the within buildings and smaller installations.

●   Double compression - this is for power plants and factories that require durable seals. These cable glands have double waterproofing and double-compression application at the cable core and outer covering or armor.

● A flexible hose is for places with higher temperatures.

●   PVC – For management cables connected to instruments.

The single and double-compression cable glands have three different varieties to be used as per requirement:

Light-duty

Weatherproof

Flameproof

●   Armoured Cable Glands:

Armored cable glands for armored cables accompany by steel-wire armored (SWA) cables. These are the standard cable for underground and wall cabling installations. The steel mesh protects the cable from injury.

● Waterproof Cable Glands:

They offer IP68 waterproofing, i.e., they resist immersion in water of one meter or a great deal of depth, use the International Protection (IP), the standard marker for resistance to water, dust, and various contaminants.

● Metal Cable Glands

These cable glands are factory-made from stainless steel, aluminum which supplies a range of benefits:

● Stainless steel offers wise corrosion and pressure resistance.

● Aluminum is flexible and rust-resistant and collectively conducts heat and electricity.

The brass cable gland is the early sort that provides strength and resistance to magnetism and deformation at low and high temperatures. It collectively provides a wise electrical, natural phenomenon. We specialize in brass cable glands that are universally in use, and it is the hardiest variety for the event and power business and various industrial areas. The six sorts of brass cables have entirely totally different uses like:

●   Indoor ─ these are better for cables, in conjunction with armored, plastic, and rubber-sheathed.

●   Outdoor - these are useful with plastic or rubber-sheathed and unsheathed cables.

● Straightening is beneficial with rubber-sheathed and unsheathed cables and employs in indoor and outdoor applications.

 ●   Weatherproof ─ these are used with plastic or rubber-clad cables. They are hard-built and provide a

strong seal having a variation designed for optimum water resistance.

●   Threaded glands are made-to-order to be employed in fixed industrial applications.

●   Industrial ─ primarily combine with plastic or rubber-clad and with armored cabling.

Rubber Cable Glands:

Some sorts of these glands have watertight seals. These seals are mass-produced from Indian rubber. Hydrocarbon is the fabric in making O-rings, a circular seal that forms a sturdy seal.

Conclusion

Thus, in the above article, we have shared the needs and applications of brass cable glands. These are also helpful in applications involving shielded cable for electromagnetic security—this helps maintain the cable's integrity by simply tightening the gland. Cable glands comply with the highest demands as regards sealing, retention, quality, and safety.
