Application

 

 

THWN conductors are highly versatile and suitable for general-purpose wiring in compliance with NFPA 70 standards, making them an ideal choice for residential, commercial, and industrial electrical installations. These conductors are rated for a maximum voltage of 600 volts, ensuring reliable performance in a variety of circuits. With a maximum temperature rating of 90°C in wet or dry locations, they are well-suited for humid or high-temperature environments. Additionally, their durability is enhanced by their ability to withstand temperatures up to 75°C when exposed to gasoline and oil, making them suitable for areas with exposure to chemical substances. THWN conductors also carry an AWM rating, providing extra flexibility for use at 105°C in dry conditions and 80°C in oil, further extending their application to specialized industrial settings. Their robust design and compliance with critical safety standards make THWN conductors a reliable choice for diverse electrical wiring needs.

Feature

 

THWN Cable

 

THWN copper wire is designed for easy installation without requiring mandatory lubrication for raceways or cable trays, streamlining the wiring process. Its PVC insulation provides exceptional electrical, physical, and flame-retardant properties, ensuring durability and safety in demanding environments. This wire is available in a wide range of sizes and colors, all of which are certified by UL and BPS, guaranteeing compliance with international and local standards for quality and performance. Additionally, it boasts a GRII rating for resistance to gasoline and oil, making it suitable for use in environments exposed to such substances.

 

Certification

 

THWN copper wire is certified by UL (Underwriters Laboratories) and BPS (Bureau of Philippine Standards), and it complies with international and local electrical safety and quality standards. UL certification ensures the safety and reliability of the cable worldwide, while BPS certification further verifies that it complies with the specific electricity specifications and regulatory requirements of the Philippines, and is widely accepted in local electrical engineering and construction projects. While complying with national certifications, the use of THWN cables also helps projects pass acceptance quickly, reduces compliance risks, and provides efficient and reliable solutions for electrical engineering in the Philippines.

FAQ

 

 

 

 

Q: What does thwn wire mean?

A: THWN wires are typically rated for temperatures up to 75°C in wet conditions and 90°C in dry conditions.

Q: What is the heat rating of THWN?

A: The heat rating of THWN wire depends on the specific version being used and the installation environment.
Dry Locations of THWN: Rated for a maximum temperature of 75°C (167°F).
Wet Locations of THWN: Also rated for a maximum temperature of 75°C (167°F).
Dry Locations of THWN-2: Rated for a maximum temperature of 90°C (194°F).
Wet Locations of THWN-2: Rated for a maximum temperature of 90°C (194°F).

Q: What is the difference between THWN and XHHW?

A: The primary difference between THWN and XHHW cables lies in their insulation material, temperature ratings, and specific applications.
    1. Insulation Material: THWN is Thermoplastic (PVC with nylon jacket for THWN-2); XHHW is Thermoset (Cross-Linked Polyethylene - XLPE)
    2. Temperature Rating: THWN is Dry/Wet: 75°C (THWN), 90°C (THWN-2). XHHW is Dry/Wet: 90°C
    3. Moisture Resistance: THWN has Good moisture resistance due to the nylon jacket.XHHW has excellent moisture resistance and is superior to THWN.
   4. Flame Resistance: THWN is Moderate flame resistance. XHHW has Higher flame resistance compared to THWN.
