THE TEST OF 363KV AND 550KV TRANSFORMER/GIS OUTLET BUSHING

---

RECENT ACHIEVEMENTS   DC superconducting bushing

---

Low temperature test：

（1）range：-196 ℃—+20 ℃;
（2）24 hour is a circle： -196 ℃ maintain15 hours，rise to +20℃ in 1 hour，maintain 8 in room temperature;
（3）12 circles (test after every circle);

TEMPERATURE RISE TEST/WET TEST

SPECIAL TEST

---

252kV transformer bushing has passed the sine resonance beat wave seismic test of 0.76g horizontal acceleration (190% of magnitude 9) and 0.62g vertical acceleration (238% of magnitude 9)（ Far more than the 0.4g requirement of the M9 earthquake)
