2.Advanced Technology:

1).One time brazing technology: All the components will be assembled in the one-time brazing furnaces, reduced the air leakage rate greatly;

2).No air leakage vacuum interrupters: Press tanks can check air leakage vacuum interrupters right away, no need to wait for long time. After your switches are sold, maybe one day your customer will call you that there is air leakage problem. But with the help of the press tanks, if you buy our vacuum interrupters, you no need to worry about the air leakage problem, we already find out the air leakage ones, even there is only one;

3).High vacuum degree: Most of our vacuum interrupters are with high vacuum degree *5pa;

4).Advanced voltage and current aging technology: Can burn the burr totally, improve lightning impulse withstand voltage and short-time power frequency withstand voltage;  

5). Free painting technology: Free painting instead of electroplate technique, very environmental;

6).Wastewater purification system: Can treat the waste water and reuse it, save the water, protect the earth;

7).Strict inspection: From parts inspection to package, we have technological process instructions, and executing them strictly, detecting the technical data, ensure every vacuum interrupter are reassuring.
