Activitate

Our advantage:
1). High vacuum degree, most vacuum interrupters鈥?vacuum degree is N*10-5Pa;
2). Low leakage rate, the air leakage rate of the dispatched expert product is less than 1/100000;
3). Dayu Hanguang vacuum interrupters have been used in China high-speed railway station projects which have been running well.

Application:
Dayu Hanguang vacuum interrupters have been widely mounted in power distribution and transmission system of electric power, metallurgy, water conservancy project, wind power generation, petroleum, chemistry, mine, railway, broadcast, communication industries.
High-quality raw material:
Our core components are purchasing from famous companies. The main components of vacuum interrupters are purchase from very famous manufactures, contacts supplier is the world鈥檚 largest contact manufacture, the supplier of ceramics also experts to USA and with high-level quality.
High-level lightning impulse withstand voltage:
The lightning impulse voltage of our vacuum interrupters are very good, for example, 12kV VI can reach up to 95kV, 24kV VI can up to 145kV, 40.5kV VI can up to 215kV, there is a report of 24kV VI, the BIL can up to 188.22kV.
Inspection Equipment:
We own high-level inspection equipment to test the ceramic, bellow; and 100% check the brazed parts of the vacuum interrupters to seek leakage ones;100% inspect vacuum degree by 3 times before dispatching; high-voltage aging can well burn the metal burr on the vacuum interrupter parts so that can make sure good quality products. Press tanks can help us seek air leakage VI in very short time, equal to lay VI in the air for 60 days.
Qualification:
Our products have already passed the type tests by the laboratories such as KEMA,KERI,CESI,CPRI India, XIHARI.
Package:
1). The packaged vacuum interrupters can be transported by vehicles, trains, airplanes, steamship and other vehicles, during automobile transportation, the allowable degree of turbulence is equivalent to a car traveling at a speed of 20km/h on a third-level road.
2). Vacuum interrupters should be stored in the ventilated, dry, non-corrosive atmosphere room.
3). Each vacuum interrupter is accompanied by a product certificate, and each box is accompanied by an installation manual.
4). The storage warranty period is eighteen month.(From the dispatch date)

Annual meetings and employee activities:
People oriented:
Dayu Hanguang always takes improving the treatment of employees and increasing the salary of employees and seeking more benefits for employees as the purpose. The company organizes internal activities and outdoor expansion every year. Every Spring Festival annual meeting is a carnival for employees.
Contribute to the society:
When drinking the water, think of its source. Dayu Hanguang always remains true to its original aspiration, and regards “people oriented, returning to society” as the mission of the company. The company vigorously developed charitable cause, donating to disaster areas and supporting the reconstruction with a free investment of nearly 100,000 yuan.China Vacuum Interrupter for Wind Power
