Few stage lights are suitable for one line, and they are all in Yi Deng, which is convenient for controlling and arranging scenes. In this way, the maximum power of a single lamp will not exceed 5KW (that is to say, it will not exceed 23A), and they all work for a short time. In this way, a 3×2.5 copper-core rubber flexible cable can be used from the control cabinet (dimming cabinet) to each lamp! The control cabinet (dimming cabinet) is best supplied with three-phase power, with a total power of 250KW (the simultaneous utilization coefficient should be considered, and if the simultaneous utilization coefficient is 1, the single-phase current is 379A), so that at least 3× 185+2× 95 copper core cable should be used for incoming lines.
