Thhn Thwn Copper Electric 600volts, 90º C Dry Wet Wire

       THHN/THWN Copper Conductor 600Volts,90ºC Dry or Wet 

1.Standard
  U183, UL1581
2.Applications

THHN/THWN Conductors are primarily used in conduit for services,feeder and branch circuits in commercial or industrial applications as specified in the National Electrical Code. For the type THHN, conductor is suitable for use in dry locations at temperatures not to exceed 90ºC. As for the type THWN,conductor is suitable in wet or dry locations at temperatures not to exceed 90ºC in dry locations or 75ºC in wet locations or not to wxceed 75ºC when exposed to oil or coolant. Conductor temperatures are not to exceed 105ºC in dry locations when rated AWM, which is used as appliance wiring material. Voltage rating for all applications in 600 volts.

3.Construction

Conductor:copper,aliminum,aluminum alloy, CCA
Insulation:flame retardant PVC(polyvinyl chloride).
Jacket:tough polyamide nylon,It is also resistant to oil ,gasoline and heat-resistant thermoplastic insulation with a jacket of extruded nylon or equivalent material. The wire is rated 90ºC dry only.
1:THHN:It indicates a single or stranded conductor having flame-retardant and heat-resistant thermoplastic insulation with a jacket of extruded nylon or equivalent material. The wire is rated 90ºC dry only.
2:It indicates a single or stranded conductor having flame-retardant,moisture and heat-resistant thermoplastic insulation with a jacket of extruded nylon or equivalent. The Wire is rated 75ºC wet or 90 ºC dry.
