our solutionIndustry Applications

application-1
10kV Urban Distribution Network Ring Power Supply System
It covers dense power consumption areas such as urban residential areas and commercial centers. It is required to realize flexible load distribution of ring network lines and rapid fault isolation, meet the "N-1" power supply reliability requirement. In addition, the equipment must be adaptable to outdoor installation environments like roadside and green belts, and have the capabilities of anti-pollution and rain resistance.

Industrial and Mining Enterprise Substation
Industrial and mining enterprises (such as iron and steel plants, chemical plants) have large electricity loads (the load of a single plant is ≥ 10,000 kVA) and numerous impact loads (such as motor startup, electric arc furnace operation). The equipment is required to have high short-circuit breaking capacity and long mechanical service life, meet the operation and maintenance requirements of the "Two Tickets and Three Systems" for substations, and support linkage with relay protection devices.

Internal Power Distribution System of Box-Type Substation
Box-type substations (with a capacity of 500-2500 kVA) are widely used in industrial parks and newly-built residential communities. They feature a compact size. The equipment used in them is required to be miniaturized and modular, and have maintenance-free characteristics, so as to reduce the internal space occupation of the box-type substation and the workload of operation and maintenance.

Photovoltaic Power Station
Wind power/photovoltaic power stations are mostly located in areas with high altitudes (≤ 3000m), strong sandstorms, and low temperatures (≤ -30℃). Therefore, the equipment must be capable of withstanding extreme environments. The power output of the stations fluctuates significantly (e.g., photovoltaic power generation occurs during the daytime, while wind power generation occurs at night). This requires switching equipment to be switched on and off frequently and support linkage with the station's SCADA system.

application-5
Data Center Power Distribution System
Data centers feature high load density and strict requirements for power supply reliability (annual power outage time ≤ 5 minutes). They adopt a dual backup power supply of "UPS + diesel generator". The switching equipment is required to have fast switching capability (switching time ≤ 0.1s) and low partial discharge (to avoid interfering with server signals), and be adaptable to the closed environment of the computer room (temperature: 20-25℃, humidity: 40-60%).
