Installation of Electrical Conduits for the Electrical Supply Industry

April 8, 2020

Electricity is extremely important for homes and commercial facilities. So, it is just fitting for the electrical supply industry to protect its components from any possible failures and mishaps. One component that can help the industry distribute stable power is electrical conduits. They are normally used to protect and route electrical wiring in a building or structure.

Features of Electrical Conduits

Normally, an electrical conduit is a type of tubing that can be used for protecting and routing electrical wiring. Some of them can be made from metal, plastic, fibre, of fired clay. Whenever a building or structure is constructed, electricians often install electrical conduits based on the specifications set by the authorities.

The whole system of electrical conduits is installed for numerous reasons. First, it serves as pull outlets for the conductors that are being and will be installed. This system also provides cavities for the creation of splices and taps in conductors. The conduit system is also meant to serve as mounting outlets for wiring devices and lighting fixtures. Some types of electrical conduits are also used as a bonding conductor for grounding or earthing.

Types of Electrical Conduits

Electrical conduits are typically classified by the wall thickness, mechanical stiffness, and material used for the tubing. The materials for electrical conduits determine the mechanical protection, corrosion resistance, and overall cost of the installation.

  • PVC Conduit: This type of conduit is often used in wet locations and underground applications. It is equipped with own PVC fittings, couplings, connectors, and elbows. Conduits out of PVC can be attached to one another by using PVC glue and a cleaner.
  • IMC Conduit: IMC conduits are thick and galvanised, making them a great option for outdoor installations. They can also be used in exposed walls in garages, basements, and areas where the conduit can be possibly hit or damaged.
  • EMT Conduit: EMT conduit systems are lightweight and easy to bend. They can be used within the walls. However, they are more prone to damage compared to rigid conduit or IMC.
  • Metal Conduit: There are two types of metal conduit. One type of metal conduit is flexible, which is recommended for areas with close quarters and tight bends. This can be installed in attic vents, water heaters, and other similar locations. Alternatively, another type of metal conduit is rigid, which is known to be the thickest and heaviest of all the conduits. Rigid metal conduits are suitable in extreme condition areas, under driveways, and service feeder installations.

Electrical Conduits Application

The key benefit of electrical conduits is that they can significantly protect enclosed conductors from impact, moisture, and chemical vapours. The varying numbers, sizes, and types of conductors that can be pulled into a conduit also simplify design and construction, which is better than having multiple runs of cables or a customised composite cable.

Another great thing about electrical conduits is their convenience. They can make frequent wiring changes simpler and safer. With proper sealing fittings, a conduit can effectively prevent the flow of flammable gases and vapours on the electrical system, protecting areas that handle volatile substances from fire and explosion hazards.

Metal conduit is great for shielding sensitive circuits against electromagnetic interference. On the other hand, non-metallic conduits can effectively resist corrosion. Both metal and plastic conduit can be bent to allow neat installation without needing excessive numbers of fittings.

The installation of electrical conduits for the electrical supply industry is extremely helpful in effectively distributing power to buildings, structures, and facilities. If you want to know more about electrical conduits, you can always contact us at Metro Pits.
