Bushing

  • Since October 2007, TBEA developed the first piece of 252kV bushing and served in the project of SGCC at the same year. The mainly produces OIP AC bushings, Oil –SF6 type DC bushings,RIP bushings and insulating barrier system etc.
  • In January 2008, TBEA started to trial-produce 550kV bushing and brought into service in September.
  • In January 2010, the bushing of BRDLW-550/1600-4 and other four different types passed the national technique verification of China. In the early 2010, designed and developed the 800kV bushing and brought into service.
  • TBEA successfully finished the research of±500kVOIP DC bushing and trial-produced the±400kV Oil-SF6 DC bushing, which filled the space of national DC bushing field.
  • Bushing testing hall equips with one high-voltage test hall equipped with one 1000kV series resonance reactor and 3000kV impulse voltage generator, one 252kV test hall equipped with 600kV testing transformer and four bushing test stations.
