Product Details
APPLICATION:
Stranded Tinned Copper Wire is an uninsulated electrical conductor made up of multiple fine strands of copper twisted together. A soft drawn conductor is either hot dipped or electroplated with tin. This process significantly improves corrosion resistance. It contains no insulating jacket or protective coating, with its key characteristics coming from its flexibility, high conductivity, and resistance to corrosion.

CONDUCTOR:
Stranded tin coated copper conductors available in soft temper only.

NUMBER OF STRANDS:
7

RATED STRENGTH

DC RESISTANCE AT 20ºC
0.12520 Ohms/1000 ft.

AMP RATING:
265 Amps



All values are nominal and subject to correction. *Ampacity based on 75°C conductor temperature; 25°C ambient temperature; 2ft./sec. wind in sun.

AWG, or American Wire Gauge, is the standard system used primarily in North America to measure the diameter of electrical conductors. This system is critical because a wire's size directly impacts its electrical resistance and how much current (ampacity) it can safely carry. A key principle is that the smaller the AWG number, the larger the wire's diameter; for instance, 12 AWG is thicker and can carry more current than 14 AWG. Sizes beyond 0 AWG are referred to as "aught" (e.g., 1/0, 2/0). Selecting the correct AWG is essential for safe electrical installations, preventing overheating, and minimizing voltage drop.
Voltage drop is the natural reduction in electrical potential that occurs as current travels through a circuit, from the power source to a device. This happens because all wires inherently have resistance, which converts some electrical energy into heat, leading to a loss of voltage. While minor voltage drop is normal, excessive amounts can cause problems like dimming lights, slow or overheating motors, and erratic electronic behavior. It can also lead to higher energy consumption and, in severe cases, create safety hazards due to overheating wires. Key factors influencing voltage drop include the wire's length and thickness (gauge), the amount of current flowing through it, and the quality of electrical connections.
In electrical wiring, amps (amperes) measure the rate of electrical current flow. Think of it as the volume of electricity moving through the wire at any given time. Crucially, every electrical wire has an ampacity rating, which is the maximum current it can safely carry continuously without overheating. Exceeding a wire's ampacity can lead to insulation damage and fire hazards, highlighting why proper wire sizing based on expected amperage is vital for safe electrical systems.
A wire's ampacity, or its safe current-carrying capacity, changes with temperature primarily because of two factors. First, the electrical resistance of copper and aluminum wires increases as they get hotter, causing them to generate more heat when current flows. Second, every wire's insulation has a maximum temperature limit; exceeding this can cause degradation and safety hazards. Therefore, in hotter environments, a wire must carry less current to avoid exceeding its insulation's temperature rating. This ensures the wire remains safe and functional, preventing overheating and potential failures.
We aim to provide authentic, precise images of each wire; however, with various product variations, it can be challenging. In such instances, we focus on showcasing the fundamental design. Always refer to the product specifications rather than relying solely on images.
