1.Product Description

This specification describes single conductor THWN or THHN, a general purpose building wire insulated with polyvinyl chloride (PVC) and covered with a tough protective sheath of nylon intended for lighting and power circuits at 600 Volts or less, in residential, commercial and industrial buildings. The wire may be operated at 90°C maximum continuous temperature in dry locations and 75°C in wet locations and is listed by Underwriters Laboratories for use in accordance with Article 310 of the National Electrical Code. The wire shall also be C(UL) listed as Types T90 Nylon or TWN75, FT1 indicating suitability for use in accordance with the Canadian Code.

4.Characteristics

 

1. Easy to wear.The diameter of wire is short, and the friction coefficient is obviously reduced.

2. Increase the threading capacity of wire conduit.The diameter of the wire is short, and the tube with the same size can be penetrated with more flow.

3. Excellent wear resistance reduces the damage to insulation when wiring and laying.This point is very important, can effectively reduce latent short circuit accident hidden trouble.

4, Excellent hydrocarbon resistance, good chemical stability, which has excellent resistance to oil, liquefied petroleum gas and gas corrosion performance, effectively improved the reliability and service life of the wire cloth .

5. High safety performance.The THWN wire has good thermal stability and thermal resistance.This will help to avoid the possibility of a short circuit failure due to a copper wire insulated by the insulation of the wires.

6. Have the ability to withstand considerable short-circuit current, and the temperature is higher than ordinary PVC type in 5 seconds.This is because there are the nylon sheath, and nylon melting point is 215 ℃.

7. It has the same flame retardant properties as PVC insulation.According to the expert test, the toxicity of its combustion is much less than that of PE.
