This product complies with standards such as IEC 62271-1, VDE 0671-1, EN 62271-1, etc. Safe and reliable, unaffected by external environmental factors, able to resist harsh natural environments, unaffected by altitude, sealed for life, and maintenance free for 35 years. Adopting modular design and flexible configuration. Single pole closure completely eliminates phase to phase faults, with the worst-case scenario being only a single phase to ground fault, minimizing the risk. The busbar and circuit breaker chamber are single pole enclosed and located in different chambers. In the event of a fault at the circuit breaker chamber or cable connection, the busbar does not need to be powered off. The faulty component can be replaced while the busbar is running with power, and only the faulty switchgear needs to be powered off.
Currently widely used in: airports and ports, public transportation and railways, the paper industry, mining and metallurgy, steel and aluminum industries, cement industry, etc.
