Equipments

For more than ten years development, we have become a integrative corporation with research, design, trial, manufacture, test, sale and after sales-service. In recent years, our corporation has invested so much for equipment, and now we are in possession of constant temperature, constant humidity workshop with 100,000 degree cleanness, production lines imported from ITALY, GERMANY and KOREA, high voltage test equipments, all kinds of instruments, database system and "ERP" management system and so on. We are also in possession of a worksite which is safe, effective, high quality and harmonious by implemented successfully "5S"(worksite management) and TPM (total production management).
With advanced equipment, scientific management and the spirit of working hard and reality, we can guarantee the quality of product for clients.

New technique

Metallization safe membrane: In require to security very among the harsh environment for use , and honour electric material adopt new-type import metallization safe membrane in condenser product design, metallization safe membrane with even to distribute in whole metallization electrode thousands upon thousands miniature fuses in the area replacing the anti-blast organization of security of the condenser. Is it loss light, since reliable and high security advantage extremely to have.

Ability of experiment

We can implement all routine tests and type tests defined by IEC 61881:1999.

Type tests:

Routine tests:
a)mechanical tests a)external inspection discharge
b)voltage test between terminals b)voltage test between terminals and case
c)voltage test between terminals and case c)voltage test between terminals and case
d)surge discharge test d)capacitance and tanδ measurements
e)sell-healing test e)test of intermal device
f)environmental testing; mechanical testing f)sealing test
g)capacitor tangent of the loss angle (tan) measurement  
h)thermal stability test  
i)test of internal discharge device  
j)resonance frequency measurement  
k)endurance test between terminals  
l)disconection test on fuses  
m)destruction test  

 

Compare between film capacitor and Electrolytic capacitors

 

Film capacitors

Electrolytic capacitors
Will handle surge voltage up to 2 times rated voltage • 1.2 max
Will handle a reverse voltage • No reverse voltage
Able to withstand a fast discharge • No

Designed for high rms current up to ~1Arms /µF

• ~40 time less

Dry or vegetable oil filled => no pollution risk

• Acid filled

High reliability

• MTBF 10 times less

End of life -5% capacitance (maximum)
 Can be used after this theoritical end of life

• -30% capacitance

Can be stored without any problem

•  Need to reform it after a long storage
