Application

 

 

UL 83 Copper THW Building Wire is a copper conductor designed for power and distribution circuits. It is widely used in service, feeder and branch circuits in residential, industrial and commercial buildings. This wire complies with UL 83 standards and is suitable for cable ducts or other recognized electrical conduit systems. Its main application areas include general purpose grounding and power transmission and distribution circuits, and can withstand a certain degree of mechanical stress and environmental factors. Due to its excellent conductivity and heat resistance, UL 83 Copper THW Building Cable is widely used in a variety of building electrical installations.

Feature

 

THW wire

 

UL 83 copper THW building wire is a single-strand copper conductor cable with a stranded design and insulated with moisture-resistant, flame-retardant and UV-resistant PVC material. The cable is available in a variety of colors to meet different installation needs. It meets a range of international standards, including ASTM B-3 (soft or annealed copper), B-8 (concentric stranded copper), B-787 (combined stranded copper), as well as UL 83, ICEA S-95-658/NEMA WC-70 and Federal Specification A-A-59544. It has a VW-1 flame retardant rating, can withstand temperatures up to 90°C in wet or dry environments, is resistant to sunlight, oil and gasoline, and complies with the RoHS directive to ensure it meets environmental requirements.

 

Certification

 

THW Building Wire is UL certified, which means that the cable meets strict electrical safety, performance and quality requirements. THW cables that have obtained UL certification comply with national and regional regulatory requirements, thus avoiding legal risks and compliance issues. This facilitates the product's entry into the global market, especially in the North American market, where the UL mark is regarded as an important indicator of product compliance with safety standards.

FAQ

 

 

 

 

Q: Can THW cables be used outdoors?

A: Yes, THW cables can be used outdoors, but they are not suitable for long-term use. They are UV-resistant and can withstand sunlight without being easily degraded or damaged by UV rays. Although they are somewhat weather-resistant, long-term exposure to extreme weather conditions or physical damage may require additional protection or the selection of cables designed for outdoor environments (such as THWN or USE-2).

Q: Is THW cable resistant to oil and gasoline?

A: Yes, THW cables are resistant to oil and gasoline. The outer sheath is made of PVC (polyvinyl chloride) material, which can withstand the effects of oil and gasoline and is not easily aged or damaged by contact with these substances. However, it cannot be exposed to these chemicals for a long time.
