Thus, an earth tag is employed between the enclosure and the gland.

The usage of armoring alone as the sole earthing isn’t suggested for cases where there’s a necessity for positive earthing because of great possible currents.

A series of integral earth glands are accessible.

Cable gland earthing

Cable gland earthing

On the other hand, insulated adaptors are accessible for installations where it’s needed to prevent connection among the earth and cable armor at one end of the route.

An example of this is the break within the earth loop which can produce false signals.

Direct to Ground Earthing

Whenever earthing an armored cable, a series of direct-to-ground external earth link cables are employed.

They are linked to the cable gland via an earth tag.

You see:

The cable will be earthed roughly one of its one ends as a minimum requirement.

That means in the event of a short-circuit or fault, the most direct way to ground will be accomplished.

‘Daisy Chain’ Earthing

When multiple cable entries are needed in a non-metallic device enclosure, this earthing method could be applied,

An external earth cable is linked to an earth tag in every cable gland.

It should be at least one earth tag utilized to link the earthing cable straight to the ground.

Chapter 3: Cable Classification: How Many Types of Cable Gland?

According to Compression Type

Single compression cable glands

Single compression cable glands are utilized for lightly armored cables.

In case you didn’t know yet, normal cable gland is also termed as Single Compression.

As you can tell, while you stiffen the gland, the compression or grip is influenced only in one area.

For example, at the cable armor exclusively.

There’s a scope for corrosive and moisture vapor to reach the gland and therefore to the cable.

Double compression cable glands

This offer added support to the bulky armored cables exiting or entering the panel.

However, in a double compression cable gland, the compression occurs both at the inner sheath and cable armor.

This is 2 sealing.

Therefore, the likelihood of vapor or moisture entry is lessened.

Such glands are also referred to as the Flame-Proof Cable Glands or Weather-Proof Cable Glands.

The only fundamental difference between the two is that there are no cone ring and cone, as mentioned earlier.

Chapter 4: Cable Gland Size Calculation: How to Select Cable Gland Size?

When we talk about installing cable gland types, it is crucial to prepare enough.

This is to avoid any accidents and the associated stress.

Cable Gland and Cable Size

If you undertake an electrical task, one of the major consideration is what size and type of cable to employ.

Choosing one which is too small for the project might lead to the danger:

  • damaging the equipment because of the voltage drop or;
  • melting the cable insulation

You need to remember that cables come in two major types:

  1. stranded conductors and;
  2. solid conductors

Solid conductor cables are reserve typically for the cables installed in industrial and domestic establishments.

It’s not flexible as standard and thus never be utilized where movement or vibration could obstruct the cable.

What’s more:

Copper work hardens with flexing becoming brittle.

Later on, it will crack, making a higher resistance at the fracture point.

It could result in overheating.

On the contrary, standard conductor cable is also termed as “cord” in the USA and “flex” in the UK.

It’s made of dozens of thinner threads of solid copper conductors.

Such thin diameter threads enable the cable to stretch effortlessly and slide over one another inside the PVC insulation.

Thus, the stress and bending forces are lessened.

Nevertheless, frequent bending will ruin the cable in the long run.

It might cause the single strands to break in the cable.

It will decrease the overall cross-sectional area and the capability to bring its rated current, making a hotspot.

If you want to know the proper size of cable for your cable gland, there are two things you need to remember.

The first is the load which the cable needs to supply.

The second is the length of your cable.

These two have an impact on your cable size.

Moreover, the selection of cable size will be based upon these factors:

  • short circuit rating
  • voltage regulation
  • current-carrying capacity

Such factors must be assessed before you choose a cable size.

In most cases, short circuit rating and voltage regulation are ignored.

This oversight could lead in danger to personnel and property.

Short Circuit Rating

The cable size chosen must be assessed for short circuit withstand capability.

It must be based on the circuit opening period for the short circuit condition.

In short, the cable must hold with no thermal damages.

Voltage Regulation

In properly built electrical power systems, the voltage regulation is typically not an issue.

Voltages drop for extremely long runs at very low voltage.

Currency Carrying Capacity

This is based upon the thermal heating.

It’s also based upon particular spacing to allow thermal dissipation.

When this spacing is a bit smaller where the cable will be installed, then the derating of the cable is needed.

Chapter 5: Cable Gland Installation Guide: How to Install Cable Gland?

The gland size or entry thread connects to the threaded part of the cable gland.

It feeds via the sidewall of your pane or equipment.

Even though there are other kinds, the most sought after are the metric thread and PG cable glands.

The cable gland could be threaded into a tapped and drilled hole.

They can also be fed with a clearance hole, and a lock nut used to the threaded part which ranges into the panel.

A lock nut isn’t needed when using a threaded hole.

However, a lot of customers will utilize them for an added degree of security.

Extended thread versions are accessible for:

  • where it’s needed to guarantee sufficient room for a lock nut or;
  • enclosures which have special needs because of thickness

Cable Gland Installation Procedure

When we talk about cable gland installation, it should be carried while following the necessary:

  • local regulations
  • codes of practice and;
  • by brass cable gland manufacturer guidelines

Installation must be carried out only by an experienced and qualified individual.

He or she must possess the necessary skills and knowledge in the installation of cable glands.

By the above, this cable gland installation instruction will help you.

It will guarantee that the installation of your cable glands will have a reliable and safe connection.

  • Care must be taken to prevent any damage to the entry threads every time to install and handling the cable glands.
  • Don’t install the cable glands while the circuits are live. After you energize the electrical circuits, your cable glands shouldn’t be opened or dismantled until the circuit has been de-energized safely.
  • The components of cable glands aren’t interchangeable along with those of other cable gland companies. Components from one plastic cable gland manufacturers can’t be utilized in that of another. Doing so will impact the safety of your installation. It will also invalidate any blast protection certification.
  • Care must be taken to prevent exposure of the gland sealing rings to chemical substances, dirt, and other foreign bodies.
  • Cable gland sealing rings are covered in the cable gland if transmitted from the factory. There must be no cases where the sealing rings should be eliminated from the gland.
  • A cable gland isn’t a user-serviceable item. That means spare parts aren’t allowed to be supplied for items that have been put into service.

Cable Gland Installation Instructions

Here is the installation instruction of your cable gland.

  • Push the cable through the diaphragm seal
  • Pre-fitted cable guide could now be rejected
  • The diaphragm seal could be rolled back to ease assembly when needed.
  • Spread the braid or armor over the diaphragm seal until the end of the braid or armor is against the shoulder of the armor cone.
  • Place the armor clamping ring.
  • Position the entry and position over the diaphragm seal.
  • Adjust the sub-assembly to reach the entry.
  • Hold the entry in position along with a wrench or spanner to avoid rotation.
  • Hand tighten the middle nut to the entry and turn extra ½ to ¾ of a turn with a wrench or spanner.

(It’s very crucial that you support the cable to stop it from twisting.)

(If you want to ease wiring within the enclosure, it might be advantageous to strip the inner sheath of your cable.)

  • Unscrew the middle nut and check that the braid or armor has been clamped successfully between the armor clamping and diaphragm seal.
  • When braid or armor isn’t clamped, you need to do the assembly again.
  • Reassemble the middle nut into the entry component.
  • Make sure that you tighten up the middle nut ‘till handing tight.
  • With the use of a spanner or wrench, turn the nut via ¼ turn.
  • Tighten the back nut to create a seal within the cable, then tighten it further full turn.
  • Make sure that the middle but doesn’t rotate when you tighten the back nut.

(Take note that the deluge seal on this cable glands locates on the assembly.)

(It needs no further action.)

(You can locate the shroud over the cable gland, if necessary.)

How to Fix Cable Gland?

For Standard Connectivity

  • Stripped cable sheath & shield
  • Outside of the circle with the discretion of retaining layer cut at least 15 millimeters
  • Out of cable waterproof cable gland
  • Eliminate the outer sheath
  • Pull the cable, so there will be contact with cable shield reed

For Thin Metal Wire Without a Layer within the Nursing
