This product has absorbed foreign advanced technology, it is small in size, which is only 50% of the protection of ordinary switch cabinet; the circuit breaker has high reliability and good performance,”Five The “anti-” interlocking mechanism is reliable and simple. The switch cabinet is an indoor complete set of 3.6, 7.2, 12KV three-phase alternating current 50HZ single busbar segmentation, as To receive and distribute electrical energy. It also has the functions of controlling, protecting and monitoring circuits, and can be used in various types of power plants, substations, and industrial and mining enterprises.High-rise buildings and other places can also be combined with the ring network to be used in opening and closing stations.
