Cables when used do not come in an open environment. They are always enclosed in a cabinet-like structure, to protect it from damage. Many types of closed cabinets and structures are available in the market for protecting the cables. But one of the most used ones is a conduit system.
Electrical conduit systems are used generally in many applications for covering the cables inside them from external exposure and damage. Every electrical engineer is generally required to know this system for proper installation and design.
In this post, we will see the concept of an electrical conduit system.
An electrical conduit is a cable enclosure cabinet system, in which cables are closed and fixed under a metallic pipe. As pipes are fixed and non-removable, the cables are protected permanently inside them. Due to its protective nature, they are used in locations like crawl surfaces, basements, wall surfaces, and outdoors.
The most common types of materials used in conduit systems are plastic and metal. As the cover is not removable and fixed, the installation and commissioning must be done strongly and efficiently so that frequent troubleshooting is not required. Refer to the below image for understanding.
Conduits provide cavities for splices and taps in conductors. This means suppose there are various conductor ends in the cable trays. These conductors must be connected properly by cables with minimum damage and maximum performance.
For this, conduit systems will provide proper routing and protection by joining conductors at various ends with cables. Also, conduits can run in various bends and mountings to provide flexibility in connection.
Some of the main types of conduits are mentioned below.
Because you are enclosing cables in proper cabinets, it is necessary to decide how to choose the best conduit system for your cabling. There are many factors which need to be considered for selecting the system according to your requirements.
Have a look at them below:
