THHN cable
THHN cable Useage
THHN cable is utilized in the construction of almost every industrial, residential and commercial building. It is is generally used to carry electrical current to all external uses of power in a building or dwelling. THHN cable may also be used for wiring of machine tools, control circuits or on certain appliances.
Due to its nylon coating, THHN cable is not a very flexible product. This can often be a factor for many contractors or end users since there is usually a preference to use a product that saves energy and time during installation.
THHN cable Properties
The different letters in THHN cable denote particular properties of the cable: T for Thermoplastic, HH for High Heat-Resistent, and N for Nylon Coated . It is these properties that set THHN cable apart from hundreds of other cable wires on the market, and what makes it an extremely valuable component for any construction initiative.
It is manufactured in copper or aluminum and covered in a PVC (polyvinyl chloride) insulation with a nylon jacket.
When it comes to integrating THHN cable into your project, it is important to understand that THHN is UL listed with a rated 90 degrees Celsius in dry locations or 75 degrees Celsius in wet applications with a THWN rating. The majority of THHN cable carries a dual rating on the cable marked THHN / THWN for both the wet and dry temperature rating.
These characteristics make THHN cable an excellent choice for controlling outdoor factors that would otherwise alter the performance of wire cable. For end users, this means greater flexibility for applications like push-button stations, fire alarm controls, and temperature control systems.
THHN cable uses a thinner PVC insulation which is a key factor in terms of its electrical properties. This thinner insulation can often lead to a current leakage and even a breakdown during chemical or environmental exposure. The PVC insulation in THHN also creates a toxic smoke when burned therefore making it undesireable in certain applications.
Cost Effectiveness
THHN cable has grown in popularity since it is a cost effective alternative compared to other types of building wire.
For indoor and outdoor applications where longevity is valued, THHN cable provides the peace of mind that contractors and homeowners demand. Because THHN cable is UL-approved for permanent installation, it is commonly used in new construction and a variety of other projects where the wire will not need to be removed. This saves money at all levels of the construction process, from initial purchase through service invoice.
