Want to protect and route electrical cables?

A conduit is a tube that’s designed to carry electrical wiring in domestic, commercial, and industrial buildings and structures. Its main purpose is to protect the encased wires against fire, mechanical damage, water, and corrosion.

There are two common types of conduits: metallic and non-metallic.

In today’s article, we’ll be looking closely at non-metallic conduits – including the different varieties, their uses, and benefits.

What are non-metallic conduits?

Non-metallic conduits are usually made from PVC (polyvinyl chloride), the third most widely used synthetic plastic polymer in the world.

When used for applications above ground, conduits must be flame-retardant, tough, and resistant to the elements (i.e. heat, sunlight, low temperatures, etc.).

Unlike its metal counterpart, which is typically reserved for protecting sensitive circuits, a non-metallic conduit can be used above and below ground, in multiple or parallel run configurations.

Types of non-metal conduit

Supplied in both rigid and flexible forms, there are several types of non-metal conduits to choose from – each one offering its own properties and benefits for different applications.

These include:

  • Rigid non-metallic conduit (RNC) – a non-metallic, unthreaded, smooth-walled type of tubing, often made from PVC and used in wet locations.
  • Electrical non-metallic tubing (ENT) – a thin-walled corrugated tubing that is moisture-resistant and flame retardant. ENT is also flexible and pliable, making it an excellent choice for encasing wires inside walls.
  • Liquid-tight flexible non-metallic conduit (LFNC) – a PVC conduit with a smooth inner and outer surface, widely used in heating, ventilation, and air conditioning (HVAC), power plants, and various other indoor and outdoor hazardous locations.

Here the team at Flex-It share the key advantages of using non-metallic conduits.

4 reasons to use non-metallic conduits

1.    Resistant to moisture

Non-metallic conduits provide excellent protection from moisture ingress – making them ideal for underground applications and wet areas in industrial and commercial environments. They essentially prevent water, oil, and dirt from getting in.

2.    Resistant to corrosion

When compared to metal conduits, non-metallic conduits offer more resistance to corrosive substances. Materials such as PVC and polypropylene don’t break down when they come into contact with saltwater or other chemicals.

This explains why they are becoming more popular in underground installations in domestic, commercial, and industrial settings.

3.    Easy to install

Non-metallic flexible conduits are super simple to install. Whilst they are all lightweight and designed to keep wires neat, tidy, and safe, some are split to make cable insertion even easier. Ideal if you ever need to replace a damaged or faulty cable and don’t have much time.

4.    Cost-effective

Whilst all conduits are priced competitively, non-metallic conduits tend to be the least expensive option. Great if you’re on a budget and looking to protect electrical cables either above or below the ground.

It’s worth noting that non-metallic conduits are sold in various coil lengths – ranging from 25m up to 100m. So, to help keep your costs low, work out the required length and purchase the most suitable product for your application.

Benefits Of Non Metallic Conduits FAQs

Non-metallic conduits are unbelievably versatile and provide a reliable cable management solution for several indoor and outdoor applications.

They’re suitable for use in wet, dry or oily locations and are best used in commercial or industrial projects – but this isn’t to say that you can’t use them to tidy up your cables at home, in your living room for instance.

Typical uses include ground burial, HVAC (heating, ventilation and air conditioning) units, pools and spas.
