The Advantages of THHN Wire

If your building project you are purchasing for needs wires that are strong and can handle heat easily, THHN wire is the right choice for you. However, there are many other advantages to using this type of thhn wire:  

1. Handle High Voltage 

THHN cables can withstand voltages up to 750 VOLTS.  Its copper conductors allow it to handle such high voltages with no problem.  

2. Used in Both Wet And Dry Environment

Most THHN wires can now be used in wet and dry conditions thanks to the existence of the double rating, which allows you to be independent of their installation environment.  

3. Durability 

Robustness and stability make it resistant to the possibility of damage and wear.  

4. Affordability 

THHN is a very economical and efficient choice for building wire. You usually just need to search the Internet to find more reliable thhn wire manufacturer or supplier. What's more the manufacturer and suppliers in China has been improving the ability to supply thhn wire or thwn wire with more excellent quality, the buyers and purchasers can find the appropriate and more reliable manufacturer supplier easily

Common problems with THHN Wire  

1. Does THHN have to be used in the pipe?  

Yes, the cable THHN must be placed in some speical pipe. It cannot be installed in any building without plumbing, otherwise the nylon jacket easy to be hurt, what's more the inside of pipe must be smooth without any parts maybe cause the scratch.  

2. Can THHN wire be used outdoors?  

THHN wire is suitable for both outdoor and indoor use, usually used in outdoor is more common compared to the indoor.  

3. Can the cable THHN be buried?  

If used in pipes, it can be placed underground. However, it cannot be used for direct burial alone, of course now there also are the thhn wires could be buried directly, but the price is highly.  

4. How deeply should the PVC pipe be buried?  

This is only regulated in the United States and if it is in the United States, according to the National Electrical Code, nylon coated thhn wire must be buried 18 inches in a rigid nonmetallic conduit. At this depth, any wires in the conduit, including PVC nylon sheathe thhn wires, will not be disconnected or disturbed by normal digging.  

Conclusion:  Nylon sheathed THHN wire has high strength heat resistance and various wear resistance and advantages convenient for application, but it still has a relatively small number of common problems, for this case, I believe that we already knew how to use the nylon sheathed thhn wire better. Of course only like this we can avoid the situation we referred above again.  

Above we summarized for purchasers and buyers so much about nylon coated THHN wire including the advantages and the common problems of nylon sheathed thhn wire.
