Product Information

Insulated conductors – or insulated wires – are your cable conduit fill. Make sure you use the right wires for your application. For instance, don’t use THHN in wet conditions; it’s rated only for dry and damp locations. Here are the most common types used. Conductor Typically houses and protects electrical power and telecommunications cables, e.g. an outdoor utility cabinet or an outdoor telecom equipment cabinet They are also the perfect solution for cables in applications that require a high degree of corrosion protection, but where protection from ingress of water is not required. With their temperature range sitting at -100°C to +600°C, you can be assured that this material is perfect for the job. The flexible stainless steel conduit range on offer from Flex-It is more than durable enough to cope in the most challenging of environments.

These stainless steel conduit products are known for their versatility, as they are found in many applications that span a number of industrial fields. The most popular of these uses are in the steel, foundry, marine and shipbuilding industries. A flexible stainless steel conduit is also the ideal choice for outer casting for temperature measuring devices and sensitive fibre optics.This chart for conduit size for cable is based on the 2017 NEC and uses common conduit types and wires. If you don’t have access to the NEC book, you may find it helpful in determining how many wires you can safely place in conduit. Manufactured from polypropylene, this type of conduit is very lightweight and easy to use. It also has a tendency to sustain harsh environments and offers excellent chemical resistance. The polypropylene flexible conduit is non-corrosive which means it can withstand impacts and toxic materials that may pass through cables. Returning to the example in Step 2, you’re using a total of 6 wires. This means that your maximum fill percentage is 40%. You already have your total wire area, so you can now calculate the minimum conduit area:

The split conduits we supply, here at Flex-It, are made from polypropylene. Thanks to the material’s high melting point, and resistance to detergents, water and acids, it’s ideal for a variety of applications. These include: Using the wire cross-sectional areas you’ve already calculated, you can now determine the minimum conduit size that you need. If you’re using electrical metal tubing (EMT) conduit, you’ll see that the closest size that you need is a 1 in conduit, which gives you a 39% fill. Conduit cable fill chartAvailable in a variety of sizes, you can easily find the perfect size to fit your bundle of cables in. You need to choose your fill table. This will depend on the type of conduit and wire that you’re using. You know the number of wires you need and the insulation type. The NEC book will tell you the gauge. Now you just need to determine each wire’s cross-sectional area and total these up.
