SF6 gas-insulated transformers are characterized by their outstanding nonflammability, insulation effects, and safety. Fully gas-insulated substations, adopting a combination of these transformers and switchgears, offer extra ease for safety assurance, accident prevention, and inspection/maintenance.
Gas insulated
transformers, using incombustible SF6 gas as insulation and cooling medium,
enable to remove a fire fighting equipment from transformer room.
˙ Non tank-explosion
Pressure tank enables
to withstand the pressure rise in case of internal fault.
˙ Compactness
By directly
coupling with gas-insulated switchgear, substation space can be minimized as
the result of compact facilities.
˙ Easy installation
Oil or liquid
purifying process is not necessary in case of gas insulated transformer.
˙ Easy inspection and maintenance work
Only SF6 gas
pressure shall be basically monitored during periodically inspection.
