With the progresses of our country in the basic scientific research, the new medium SF6 gas has been pushed to the application filed of the power equipment by new material and new process application. SF6 is widely applied as a new insulating medium due to its excellent insulating property and arc quenching performance and noninflammability.
Our company has successfully researched the inflatable light-weight testing transformer after years of efforts. Compared to the traditional oil-immersed light-weight testing transformers, this series of products is 20%-60% lighter (depending on the voltage and capacity levels), and has no oil contamination. The voltage level of single testing transformer can reach to 300kV. Because of using of the new production process, the product technical performance is much improved, and the product is especially applicable to the use under the site working and frequent moving.
No-load current to transformers of different voltage level: 4-9%
Impedance voltage: 4-10%
1. Small size, light weight.
2. Clean, no oil, maintenance-free.
3. Free from harsh climate impacts, site handling still can do the test.
4. Dielectric strength significantly higher than oil type, minimal.
