warning
1. Test transformer should be applied into use with control unit as for how to use control unit please see Operation Manual of Control unit.
2. Screening wire should be applied into the direct current test to avoid straying leakage. After test discharge rod is applied to release the restored electricity.
3. The end of high frequency voltage filtering capacitance should be connected with the ground wire together with crust of control unit to connect with the earth wire.
4. The whole test should follow the regulation in high frequency voltage test site should pay more attention to the safety of equipment and body.

1. Operational Principle
PSA nitrogen generation adopts carbon molecular sieve as adsorbent whose capacity of adsorbing the oxygen in air shall be larger more than of adsorbing the nitrogen in air. By means of valve opened and closed with PLC, two columns a&b can be shifted in circulation for pressured adsorption,de-pressured dis-adsorption in turn so as to separate the oxygen and nitrogen in air, thus a nitrogen gas with purity demanded can be made.
2. Typical application
Nitrogen is used in short-circuit, large-scale integrated circuit, color and black & white picture tubes, parts of TV sets and recorders, semiconductors manufacturing, electrical equipments as well as laser drilling and other electrical components as protective atmosphere.
Power Transmission Poles used for power supplying and infrastructural projects in urban areas.
