Definition and technical parameters of power cord 2022/1/4
Definition of power cord: A power cord is a wire that transmits current. The way current is normally transmitted is point-to-point. Power cables can be divided into AC power cables and DC power cables according to their uses. Generally, AC power cables pass through AC cables with high voltage. Such cables can be formally produced by the safety certification party with unified standards due to high voltage. And DC line is basically through low voltage DC, so the …… [Check the details]

Five-step process for making power cables 2022/1/4
1. Copper wire drawing, is the first process of power cord production, at room temperature, the application of wire drawing machine through a or a number of tensile die hole, so that its section is reduced, length added, strength improvement. 2 Power line monofilament annealing, copper wire heating to a certain temperature, by recrystallization method to improve the toughness of monofilament, reduce the strength of monofilament, in order to meet the requirements …… [Check the details]
