THHN THWN-2 Copper Building Wire
[pdf] [/pdf] [short] THHN THWN-2 Copper Building Wire Applications: THHN stands for thermoplastic high heat-resistant nylon. Known for versatility and durability, it is the most co mmon type of building cable. The double marking THHN /THWN-2 indicates that the electrical wire is suitable for wet and dry conditions equally (The letter "W" means that it is water-safe). Additionally, the cable is resistant to corrosion, excessive dryness, and the impact of chemicals. It also performs well in cold bending. The building wire is rated 90 degrees Celsius in both wet and dry locations. Nassau National Cable sells THHN THWN-2 copper building wire sized between 4/0 and 1000 MCM. The electrical wire is rated at 600 V. THHN/THWN-2 is used in a variety of applications in conduit and raceways. Common uses include service cable trays, electrical feeders, and branch circuits. Generally, the purpose of the cable is to ensure power transmission in control systems and in lighting circuits. THHN THWN-2 can also serve as control wires in smaller setups, and small-sized cables used to detect changes. The cable is extensively used in various control systems like automotive plants, wind energy, forestry equipment, oil and petroleum equipment, processing equipment, packaging facilities, etc. Due to moisture resistance, it is a popular choice for tropical regions and near-sea territories. Additionally, the cable can be used in home theater wiring, interior wiring, video checking networks, gaming networks, TV, and radio. THHN THWN-2 is often used in harsh conditions; therefore, it has to be strong, consistent, and flexible. THHN cables contribute to the safety and stability of commercial, industrial, and residential buildings because they are responsible for external uses of power. Flame retardancy and excellent resistance to sunlight, water, corrosion, and chemicals are key features of a high-quality THHN THWN-2 wire that ensure its effective performance. The cable heavily relies on the protection of its insulation. Therefore, it is important to buy the cable from a reliable seller. Also Known As: Copper wire, building cable, hook up wire, conduit wire, nylon wire, construction cable, thermoplastic-insulated copper wire, THHN-PVC tray cable. Construction: Conductors: THHN THWN-2 conductors are constructed of annealed soft copper that follows ASTM B3 and ASTM B8 standards. When it comes to building wire, copper conductors are superior to aluminum because they remain stable for a longer time. The copper conductor is strong and flexible. As a rule, the cable has 3 or 4 conductors. Insulation/Jacket: The cable is insulated with a thermoset plastic jacket (PVC) that is flame-retardant, sunlight-resistant, lead-free, strong, and stable. Without being too bulky, it ensures that the cable can be used in harsh conditions. The jacket is color-coded in accordance with ICEA Method 4. Stranding: Copper conductors are compressed stranded, which makes them easier to pull. Stranding ranges from 7 to 19 strands. Standards: ICEA S-73-532 UL 1277 (Resistant to flame, moisture, and sunlight) UL 1581, UL 83, UL 1063 , UL 758 A-A59544 ASTM B3 and B8 conductor ANSI/NFPA 70 for Safe Electrical Design and Installation RoHS compliant Safe For Commercial and Industrial Use Color-coded #1-E2 per ICEA S-73-532 May be used in NEC Class I and II systems May be used in Division 2 hazardous locations Allowed for Exposed Run (ER) and be used in accordance with NEC [/short] THWN and THHN Wire for Sale THHN and THWN cables are tray and conduit feeder wires used in branch circuits of commercial or industrial applications. They can also serve as control wires in smaller set-ups; small sized cables used to detect changes and control systems. They are designed to a gauge size of 250 to 1000 MCM and specifically used for transmission and distribution of 600V power. The cable is extensively used various control systems like automotive plants, wind energy, forestry equipment, oil and petroleum equipment, among many more. Since it has a wide range of applications, the cable is designed such as to ensure efficient current transmission, secure insulation and stable functionality. It is therefore constructed to outstanding specifications which befits the systems of applications. You can buy thhn wire online or from a reliable wire store. However, it is important to know a few attributes of the thhn wire for sale in order to make an informed decision and consequently get quality products for your money. With money-hungry cable and wire products suppliers all over, you can never be too careful these days. Here are some ideal attributes of a good thhn wire. THHN wire Conductor THHN like THWN wires are constructed using copper conductors. Copper is widely used for these control cables because it has excellent electrical properties. Copper is an excellent conductor, strong, hard enough to prevent nicks and also flexible; it entails everything you’d want in a flexible portable control wire. However, it has some drawbacks and the conductor used in this cable is modified to make it more stable and fit. The modification includes annealing to make it soft and stranding to improve its flexibility and electrical conductivity. The Copper conductor is fully annealed, stranded and bare according to ASTM B3 and ASTM B8. The number of stranding range from 7 to 19 strands while conductors range from 3 to 4. THHN Wire Insulation When you buy a THHN wire online, ensure that it has a Polyvinyl Chloride (PVC) insulation which is flame retardant and has clear Polyamide (nylon). Since the cable is to be used in harsh conditions such as in direct burial, it requires a strong, stable and reliable insulation. PVC insulation serves best, it keeps off destructive agents and maintains the conductor structure. The insulation color coding is as per ICEA Method 4. THHN Wire Jacket Cable jackets are additional security features which also contain the components of the cable. They complement the insulations to ensure the conductor security is tighter. The Tray Control cable has its jacket made of Polyvinyl Chloride (PVC) with a thickness of about 60 mils. The thicker the jacket the more secure though it causes bulkiness but this jacket doesn’t exceed 60 mils hence less bulky. This jacket system is lead-free, sunlight and flame resistant and environmental friendly. Features Tray Control cable has distinctive features: • It has a Ripcord• A 600V rating• Has THHN or THWN Insulation.• PVC Jacket• Copper conductors.• Excellent resistance to oil, chemical and sunlight.• Resistance to cold bends and cold impacts• Tray Control cable has the smallest cable Outer Diameter required for suitable applications• The crush and impact requirements that this cable has are of Type MC Cable.• It has a color code according to ICEA Method 4 Applications Tray control cable is used in various industrial plants. Generally, the purpose for the cable is power transmission in control systems and in lighting circuits. It is used broadly in the commercial and industrial applications. Some of the industrial plants where it is applied include: oil and petroleum equipment, processing equipment, packaging facilities, automotive plants and wind energy. The cable is also used in tray wiring, cold temperature storage systems and machine tool wiring. This cable can be used above ground, on raceways or direct burial method. Since it has the capacity to withstand both extreme climates of wet and dry locations, this cable serves well in either of the installation methods. Install it indoors or outdoors, in aerial systems or conduits, in cable ducts, cable trays or directly buried provided the circuit voltage exceeds not 600 volts. The cable has passed the flame tests by IEEE and is also resistant to oil and other chemicals. These make it sturdy, strong and reliable when used in control systems for oil industries where chances for fire outbreaks are high. Its high flexibility befits it for wind energy and automotive plants where movements are frequent. With high electrical conductivity and stability to temperature variance, the cable makes a good control system. Operation One thing you have to be keen on before you buy a THHN Wire is its temperature approvals, lest you buy a cable that will succumb to adverse effects of the environment. A good THHN cableshould be approved for effective operation at 900C in dry locations and 750C in wet places. It can sustain a temperature of up to 1300C during emergency overload and 2500C for short circuit conditions. The cable is rated at 600 V. Approvals and Certifications • UL approved for use continuously in the above mentioned conditions• Approved for direct burial• May be used in NEC Class I and II systems• May be used in Division 2 hazardous locations• Allowed for Exposed Run (ER) and be used accordance with NECWe hope that you’ll find this information valuable when you buy THHN wire online.
