Why THHN copper Wire is used so Popular in Philippines?

In the Philippines, with the seasonal increase in residential construction and commercial construction projects, you may see a rise in the demand for construction wiring by many engineers. The most popular power distribution solution throughout the structure is THHN copper wire. THHN building wiring is commonly used to carry electrical current to all power circuits in a building or residence. THHN wire is used in nearly all electrical plans in industrial, residential, and commercial buildings.

THHN copper wire has a thermoplastic high heat resistant nylon jacket. THHN is available in stranded or solid conductor designs depending on the size supplied. It is made of pure copper or aluminum and has a combination of polyvinyl chloride (PVC) insulation and nylon jacket. THHN is UL83 certified, so thhn wires can be used in the US.

THHN wire usage environment
 

THHN wire is rated at 90 degrees Celsius in dry environments and 75 degrees Celsius in wet environments, with the same performance as THWN. THHN construction wires are almost always marked THHN/THWN, have double labels on them, and are also suitable for wet and dry temperature ratings. In industrial applications, THHN wires are often used in the wiring of machine tools, control circuits, and connecting wires for common household appliances and electronic products.

How THHN wire differs from other construction wires
 

Compared to other construction wire products, THHN copper wire has several major differences. THHN wire uses thinner PVC insulation as a jacket, which is a key factor in its wide range of electrical properties and uses. Due to its durable nylon coating, THHN wire lacks the flexibility of some other products. This rigidity is often a plus for contractors and end users, as its easy-to-lay feature saves installation time.

Okay, that's all for the introduction to "Why THHN wires are used in almost all industrial, residential and commercial building plans in the Philippines." Hope it helps! It is recommended to continue to pay attention to Jianzhenda Cable to learn more about wire and cable information.
