Four Types Of Electrical Conduits

15 Jul

Electrical conduits protect the electrical wiring and offer a route for the wiring. Conduits are manufactured using a wide variety of materials such as plastic, fibre and metal. The electrical conduits are available in two models, rigid conduits and flexible conduits. Each model has its share of pros and cons. Electricians should make the choice of material and model depending on the national code for wiring of different buildings.

The ราคาท่อโลหะ depends upon the metal used to manufacture the conduit and its other features. Here are some types of commonly used electrical conduits.

  1. Galvanized rigid conduit – The rigid conduit is made using galvanized steel. These conduits are used in industrial and commercial buildings. Electrical Metallic Tubing is a variant of the rigid electrical conduit and is made of steel or aluminium. The ราคาท่อโลหะ is cheaper than the galvanized rigid conduit and it is extensively used in commercial, industrial and residential applications.
  2. Liquid tight flexible metal conduit – This conduit is produced with hot-dipped galvanized steel and does not rust. The flexible metal is designed into a hollow tube which covers the wiring and protects it from fire and dampness. Installing the flexible conduit is easy as it can be bent according to the requirements. This conduit is coated with a water resistant PVC material and offers protection from water, oil and chemicals. The ราคาท่อโลหะ changes from manufacturer to manufacturer depending upon the materials used to produce it. However, remember to buy the liquid tight flexible metal conduit from a trusted and reputed manufacturer.
  3. Aluminium conduit – This is a rigid conduit manufactured using aluminium. It is commonly used in industrial and commercial wiring applications. It is corrosion resistant and is used in concrete slabs and walls.
  4. PVC conduit – PVC conduits are the lightest and most used conduits. The price of these conduits is much less than the ราคาท่อโลหะ and hence it is very affordable. These conduits are available in different measurements to suit the requirements of different installations. These conduits are moisture and corrosion resistant but it is non-conductive. PVC conduits expand and contract depending on the temperature and are not suitable for underground settings.
