Introduction to Cable and Gland
Cable And Gland When it comes to electrical and communication systems, cables and cable glands play an indispensable role. These components ensure efficient transmission and provide safety in various environments.
What is a Cable?
A cable is a bundle of insulated wires designed to transmit electricity or data. Cables vary in size, material, and purpose, depending on their application.
What is a Cable Gland?
A cable gland is a mechanical device that connects and secures the cable to equipment. It provides strain relief, ensures sealing, and protects against external elements like dust and moisture.
Importance of Cable Glands in Electrical Systems
Ensuring Safety
Cable glands act as a barrier against environmental factors, reducing the risk of electrical faults and fire hazards.
Protecting Equipment
By sealing cables and preventing ingress of contaminants, cable glands extend the lifespan of connected devices.
Types of Cables
