5 Miniute to Know Three Questions about THHN Stranded Wire Use

Recently, our customer introduced us some technical problems about THHN multi-strand copper wire. I solved the problem for the customer in 3 minutes, and now you only need to spend 2 minutes to fully understand them. Hope that helps you.

1. Does the THHN wire need to be in the conduit?

According to local electrical installation regulations, the THHN multi-core wires of Jianzhenda Cable are usually placed in conduits for protection laying. The reason is that the THHN wire produced by Jianzhenda Cable has become the standard for many foreign households, and it is cheap and quite easy to operate. When it comes to your big problems, if you're going to wire your building in a hot environment, and you've got neutrals and grounds installed, then you have to THHN wire to make it happen. Because the THHN wire can run for a long time in a dry environment with an air temperature of 90 degrees Celsius and a humid environment at 75 degrees Celsius, just in case, the THHN wire needs to be placed in a conduit for protection.

2. What is the use of THHN multi-strand copper wire?

THHN wires are single or multiple wires coated with plastic that are easier to pass between conduits or walls. It is used for mains energizing use in general buildings, such as residential and commercial wiring. It can be used in temperature environments up to 194°F or 90°C.

3. Can you use THHN multi-strand copper wire for automobiles?

Some people may be curious, the conductor of the thhn wire is twisted by multiple strands of relatively thin copper core wire, is this possible for use in automobiles? I then sent the question to our electrical specialist. We know that THHN stranded copper wire will work as long as it is kept away from heat sources; it is rated up to 90°C. It is UV, gasoline and oil resistant so it can be used in automotive applications. But we need to take care that the voltage value matches the rated voltage of the car.

THHN stranded wire multi-stranded copper core is usually composed of multiple THHN wires twisted together and sheathed with polyvinyl chloride (PVC).
