Every day in the production of power lines, power lines over a day to 100,000 m, plugs 50,000, such a large data, and its production process must be very stable mature. Through continuous exploration and research and European VDE certification bodies, national standard CCC certification, UL Organisation, BS certification bodies, certification bodies ........ Australia SAA approved, the power cord has matured to the following profile follows:
1. Power cord copper, aluminum single strands System
Power cord commonly used in copper, aluminum timber, at room temperature, applied through a drawing machine or the number of road stretching the die hole, to reduce the cross-section, add the length and strength progress. Drawing is the first of the wire and cable company procedure, drawing with the primary process parameters are model craft.
2. Single-wire power cord annealing
Copper, aluminum filament heated to temperatures necessary to approach to the progress of recrystallization the toughness of a single wire, reducing the strength of a single wire to fit on the conductive core wire and cable requirements. Annealing process is crucial to eradicate the oxidation of copper....
