Conductor Copper Soft - Drawn 19 Strands PVC Insulated Single Overhead #2/0 #2 #4/0 Type THW Product Summary​ I. Product Composition and Structure​ This overhead conductor features a 19 - strand soft - drawn copper construction. Soft - drawn copper conductors are known for their enhanced flexibility. The soft - drawing process reduces the internal stress within the copper, making it easier to bend and install, especially in complex overhead wiring scenarios. This property is crucial as it minimizes the risk of wire breakage during installation and maintenance.​ The conductor is insulated with PVC (Polyvinyl Chloride). PVC insulation offers excellent protection. It is highly resistant to abrasion, which is important in overhead applications where the wires may be exposed to various environmental factors such as wind - driven debris. Additionally, PVC is flame - retardant, providing an extra layer of safety in case of electrical malfunctions that could potentially lead to fires. It is also moisture - resistant, preventing the intrusion of water which could cause corrosion of the copper conductor over time. Moreover, PVC has good oil - resistance, making it suitable for areas where there might be exposure to oil or other chemicals.​ II. Type THW Characteristics​ Type THW indicates specific temperature and voltage ratings. It is rated for 600 volts, making it suitable for a wide range of general - purpose electrical applications. In terms of temperature, it can be used in dry locations up to 90 °C. However, according to NFPA 79, the ampacity is limited to the 75 °C conductor temperature to ensure safe and efficient operation. In wet locations or areas where it may be exposed to oil or coolant, it can operate at temperatures up to 60 °C. This versatility in temperature and voltage ratings makes Type THW conductors highly adaptable to different environmental and electrical load conditions.​ III. Sizes and Applications​ Available in sizes #2/0, #2, and #4/0, these conductors are designed to handle different levels of electrical current. Larger sizes like #2/0 and #4/0 are suitable for applications that require higher current - carrying capacities, such as in major power distribution lines in industrial settings or large - scale commercial buildings. Smaller sizes like #2 can be used in less demanding electrical circuits, perhaps in smaller industrial machinery or some residential overhead wiring in areas with specific electrical requirements.​ Common applications of this type of conductor include general - purpose wiring circuits. In industrial settings, it is frequently used for machine - tool wiring, where the flexibility of the soft - drawn copper and the durability of the PVC insulation are essential. It is also used in the internal wiring of appliances, ensuring reliable electrical connections. Other applications include control panels, where accurate and stable electrical connections are crucial for the proper functioning of control systems. Wiring for refrigeration and air - conditioning equipment also makes use of these conductors, as they can withstand the temperature and environmental conditions present in such systems. Additionally, in the control wiring of machine tools and automatic washers, these conductors prove to be reliable choices due to their performance characteristics.
