How to properly install THHN cable in cold weather

The cold weather can wreak havoc on your skin tires, heating and air pressure in your own, but he also knew that destroy the wiring, when properly treated is not? A cable as it is prone to deterioration THHN cable cold.

What is THHN cable?

Cold Weather

While some of the terminology is confusing and difficult to understand cables, most of the cables with acronyms or abbreviations. The name "THHN"simply comes from "T hermoplastic, HH och eat-resistance, N-Coated Ylon. THHN cable is classified under the Hook-Up Wire and cable is a very popular, usually used as a thread of general construction. "General" simply means that different applications, all in the construction industry. Like all cables for general use, there is only one question "correct" cable THHN. However, it is very important to understand all the cables of the strengths and weaknesses, whatEnvironments can not be used.

THHN wire size

To find out where the name comes from THHN helps to identify the strengths of the cable. Why is a thermoplastic material can be heated and cooled a few times to make it more recent, but, like any other high and low temperature limits material that can withstand before unstable. These specific temperatures can vary between manufacturers.

With the "High Heat" rating in its name infers, thatcan be used at high temperatures. What practical applications will depend on the actual characteristics of the cable and the temperature must be known to determine this. "Nylon-coated" refers to a specific thermoplastic material is used. THHN, PVC thermoplastic material such as insulation, but the nylon is used as the sheath and is exposed to the elements. Nylon is a strong material and is so widespread that the cable THHN cheaper than otherBuilding cable, the most challenging environments, resist.

THHN cable weakness

The same materials that give THHN cable and give it strength and weakness in the right (or should I say wrong?) Environments. Because the nylon coating, THHN cable can become stiff at low temperatures. can temperatures below 14 ° F is subject to cracking. in the process of thermoplastic materials, work in a process called lamination constant lowTemperatures, but also for the cables are installed and then not move, it does not have to be. The proper way to allow the cable to withstand the cold temperatures of installation and then to the lowest point of the range of operating temperatures.

The term "thermoplastic" is used as a material that melts down into a liquid at high temperature and freezes at low temperatures. The cold weather becomes colder, the slightest movement causes it to rupture. Bend the wireto compress causes one side of the jacket and the other to expand, this is exactly the kind of agitation is necessary in order to cracks.

Proper installation of the cable THHN

To ensure that will not break your THHN cables during installation, is to follow a few simple steps:

Shop cable inside when the weather turns cold, stable temperature of 65 ° F is best. If this is not possible, the cables before you enter at this temperature for 24 hoursInstallation Never install THHN, when the outside temperature is below 14 ° F Even if exposed to temperatures not too cold, fall to the ground and protect the cable against impact from other objects, such as cracking stiff material.

After successful installation, THHN cable is securely placed in ambient temperatures of 14 ° F, remains at work.
