What are characteristics and of THHN building wires in the Philippines

Published by Author: Joey Wan May 22,2022

THHN stranded wire is an acronym for thermoplastic, high heat resistant, nylon sheathed insulated construction wire. Nylon material is one of the more commonly used insulating materials on wires.

Building wiring is typically used to carry electrical current to all external power usage in a building or residence. This product is used in the construction of almost all industrial, residential and commercial buildings. The THHN line is the more popular building type in the Philippines. Let's talk about the characteristics and scope of use of THHN building wires in the Philippines!
 

Features of THHN Construction Wires

THHN wire is rated at 600V, 90C and has a coated nylon insulation for easy pulling of the wire through the conduit. THHN wire is available in a variety of gauge sizes, colors and lengths. THHN wire can also be used as MTW wire or THWN wire. Wires can be purchased in small or large quantities. Solid THHN is only available in 14 and 12 gauge wire sizes.

 

The composition structure of THHN building wire

THHN stands for Thermoplastic High Heat Resistant Nylon Coating. Depending on size, THHN can be stranded or solid conductors. The conductors are made of copper or aluminum and are covered with PVC (polyvinyl chloride) insulation and a nylon jacket. Jianzhenda THHN wire has UL83 certification and is rated at 90 degrees Celsius in dry environments and 75 degrees Celsius in wet environments, with a THWN rating. In the Philippines, the vast majority of THHN construction wires are marked THHN/THWN, and the thhn cables come with multiple ratings for wet and dry temperature ratings. THHN building wire can also be used for wiring machine tools, control circuits or certain electrical appliances.

Compared to other construction wire products, THHN wire has several key differences. THHN wire uses thinner PVC insulation, which is a key factor in its electrical performance. This thinner insulating layer often leads to current leakage and even failure during chemical or environmental exposure. The PVC insulation in THHN also produces toxic fumes when burned, making it undesirable in some environments.
