THHN THWN Wire 8.0mm2 14mm2 22mm2 30mm2 38mm2 50mm2 60mm2 80mm2 100mm2 Philippines Application
THHN and THWN wire with various cross-sectional areas (8.0mm², 14mm², 22mm², 30mm², 38mm², 50mm², 60mm², 80mm², 100mm²) are widely used in the Philippines for diverse electrical applications. These wires are suitable for both indoor and outdoor installations due to their heat and moisture resistance.
THWN Wire Standards:
The copper conductors type THWN/THWN-2 meets the following specifications and standards:
• ASTM B-3:Copper Annealed or Soft Wires.
• ASTM B-8:Copper Stranded Conductors in Concentric Layers, Hard, Semi-hard or Soft.
• UL - 83:Wires and Cables Insulated with Thermoplastic Material.
• NEMA WC-5:Wires and Cables Insulated with Thermoplastic Material (ICEA S-61-402) for Transmission and Distribution of Electric Power.
CONSTRUCTION :
THWN Wire Construction
The conductors type THWN/THWN-2 can be solid or stranded and they are built with soft temper copper, they are also insulated with an uniform layer of Chloride of Polyvinyl (PVC) thermoplastic material resistant to the moisture and the heat, over which it is applied a protector coating of Nylon or Polyamide. They can be supplied in varied colors according to their size and with different packaging.
