Power Cord Manufacturing Process

Power cords are wires that carry electrical current. Usually, the way of current transmission is the point-to-point transmission. Power cords can be divided into AC power cords and DC power cords according to their uses. Usually, AC power cords are wires that pass through high-voltage alternating current. Due to the high voltage, such wires need a unified standard to obtain safety certification before they can be officially produced. The DC line basically passes direct current with lower voltage, so the safety requirements are not as strict as the AC line, but for safety reasons, countries still require unified safety certification.

Power cord manufacturing process

1. Power cord copper, aluminum monofilament drawing

The copper and aluminum rods commonly used in power cords are used to pass through one or several die holes of a drawing die at room temperature to reduce the cross-section, increase the length and improve the strength. Drawing is the first process of each wire and cable company, and the main process parameter of drawing is mold matching technology.

2. Power cord monofilament annealing

When the copper and aluminum monofilaments are heated to a certain temperature, the toughness of the monofilament is improved and the strength of the monofilament is reduced by the method of recrystallization, so as to meet the requirements of the wire and cable for the conductive core. The key to the annealing process is to eliminate the oxidation of the copper wire.
