What is a Cable Gland and Why Is it Used?
A cable gland, more commonly known as a cable connector, is used to attach the end of an electrical cable to a device. Cable glands are mechanical devices that are used in a number of devices for various purposes. One of the most common types of cable glands is brass cable glands that are used extensively in electrical appliances such as the miniature circuit breakers. Why are cable glands used? Cable glands are used in all kinds of electrical circuits and wiring. Cable glands can provide relief from strain for the electrical wiring system. ●
Cable glands provide a certain degree of necessary protection against environmental factors such as dust and other impurities which has the potential to interfere with an electrical wiring system. Brass cable glands are especially useful in this regard as the zinc component in it makes it resistant to corrosion and therefore, can provide better protection.
●
Cable glands are very much necessary for earth continuity. For armored cables where the cable glands are made of metal, these glands can be checked to see if they can withstand a peak in short circuit current.
●
The cable glands can provide a degree of holding force that provides that cable wiring with an appropriate level of resistance to being pulled out from its position.
●
Cable glands also provide the necessary sealing required for cables in case there is a high degree of protection that is necessary to keep the cable in place.
●
Additionally, cable glands, along with certain other equipment, can help maintain a level of protection for the cable sheath and wiring in an electrical system.
