They are known as complete switchgear assemblies because they integrate inside them such electrical components as circuit breakers, disconnectors, control devices, protective relays, and monitoring units into one modular solution. The interior of the cabinet is divided into busbar compartment, circuit breaker compartment, cable compartment and low-voltage secondary instrument compartment, equipped with a comprehensive. Our high and low voltage complete electrical equipment solutions are designed based on a deep understanding of the current development trends in the power industry and accurate predictions of future power demand. In distribution systems, they can be used in ring network distribution systems as well as in dual power supply or radial terminal distribution systems. Senior Electrical Engineer, with 12 years of experience in high and low voltage switchgear installation, commissioning, and overseas project technical support. Currently, Thor is the Technical Department Manager at Weisho Electric Co. It is the core component of the power system, so it is responsible for the control, protection and isolation of circuits and equipment, and is also used to regulate power flow, quickly cut off.
