testing transformer classification: 

 There are four kinds of high voltage testing transformer according to the medium points:

1. Oil-immersed high voltage transformer test: large capacity, cheap, convenient maintenance, mainstream products.

2. Inflatable high voltage test transformer : interrupter resistance, and light weight.

3. Dry typehigh voltage testing transformer: light weight, light volume, can run backward, price expensive.

4.Series type high voltage testing transformer: small volume, low voltage, light weight, easy to transport and install.

ac and dc hipot

AC DC high voltage tester set inflatable testing transformer feature:

1 , The inflatable testing transformer , small in size, light in weight ( compared with the same level of oil-immersed transformer tested 40% -65 % lighter )

2 , Clean, greaseless, no need to maintenance

3 , Weather-proof, on site testing without standstill YDQ series high voltage SF6 inflatable experimental transformer 

4 , The dielectric strength is higher than the oil-immersed testing transformer dielectric strength 

test transformer oil significantly, and the corona is minimal

AC DC high voltage tester set inflatable testing transformer parameter:  

1. Voltage class: 10kV~600kV

2. Capacity range: 1~500KVA

3. No-load current: < 7%

4. Impedance voltage: < 8%

5. Product type: AC, DC&AC, AC cascade, AD & DC cascade.

1. Q: What is the language? After sale service,the Warranty? 

    A:English version or as your requirement.Warranty : 1 year. 

2. Q: Does it output AC or DC or AC&DC? 

    A: We have AC and AC&DC, for your choice. 

3. Q: Whether does it have battery or liquid ? Convinent to delivery? 

    A: Some models have insulation oil, no battey, which does not influence the delivery. 

4. Q: Where is it used? 

    A: Testing dielectric strength ofHigh-voltage electrical equipment, electrical components, insulation material.          For example,cable, high-tension switch etc. 

5. Q: What types of testing equipment?What’s the difference? 

   A: There are dry, oil-immersed and inflatable,three types. Differences as follow:

        Dry: light weight, volume light, can rewind.

        Inflatable: interrupter resistance, and light weight.

        Oil-immersed: capacity, cheap, easy maintenance, mainstream products.

We have attended Power-gen Exhibition in South Africa on July 19-21, 2016.

and  the MEE Exhibition in Dubai on 1st to 3rd March 2016. And they are very successful. The follow is the photos that we attended the Power-gen Exhibition and the MEE Exhibition.
