Cable Gland Sizing

This post describes the types and factors to be considered while choosing cable glands.

CABLE GLANDS:

A device designed to permit the entry of cable into electrical equipment which provides sealing, retention and earthing, bonding, insulation, strain relief, or a combination of all these. The gland should maintain the overall integrity of the enclosure into which it is to be fitted.

Brass Indoor Type Gland
Brass Outdoor Type Gland
Brass Straitening Unarmoured Cable Gland
Brass Weather Proof Gland
PG Threaded Gland
Industrial Type Gland

There are numerous options available, but there is no one–size–fits–all solution. However, it does imply that you can select a cable gland based on your specifications. To accomplish so, you must first take into account a variety of
environmental and application factors.

THE ENVIRONMENT’S PART:

It makes no difference if you work in aerospace, industrial, maritime, power & utility, telecommunications, or any other critical business. What matters is that you figure out what your cable gland’s primary application environment is.
Questions to ponder:

Will you be utilizing it indoor or outdoor?
Will it be in a safe industrial zone or in a potentially dangerous or
explosive environment?

KNOWING THE TYPE OF CABLE:

Different cables necessitate different cable glands. Understanding how to install an armoured cable gland, for example, differs from installing unarmoured cable glands.
