The off circuit tap changer transformer was designed together by the related factories organized by the Transformer Research Institute. The switch adopts a new structure, new material, and new technology, having the advantages of a reasonable structure, hand-feeling good, turning flexible, and reaching the designed place accurately, etc.

The off circuit tap changer is the updated product of the non-excitation transformer octc tap changer in our country at present, applying to the three-phase oil-immersed electrical power transformer with the frequency of 50Hz, 60Hz, the rated voltage of 10KV,35KV, the rated current of 63A,125A,250A, 400A. The off-circuit tap changer transformer can be directly fixed on the box cover of the transformer, under the condition of non-excitation tapping, regulating, and changing.

Pressure relief valves play an important role in the protection of oil immersed electrical equipment, such as transformers, high voltage switch gears, capacitors and on load tap changers etc. This device can prevent the oil- immersed electrical equipment from deformation or rupture. Should a fault occur in such electrical equipment, from deformation or rupture. Should a fault occur in in such electrical equipment, they are Instant aeneous vaporizes the oil causing extremely rapid build - up of gaseous pressure. If moaning this type of pressure relief device on the oil tank, when the pressure reaches to its opening pressure, it opens automatically within 2ms and relieves the pressure.
