Description

 

The LZZBJ71-12W current instrument transformers are fully enclosed and cast in epoxy resin. The transformers are special for electric systems of rated voltage of 12kV and rated frequency of 50Hz / 60Hz. They are used for outdoor mounting. The performances of the products meet the standards IEC60044-1 and GB1208-2006.

 

Ambient condition:

  1. Ambient temperature: -25 ~ 40 .
  2. Note: For customization, the ambient temperature can be as low as -40 .
  3. Relative humidity: lower than 85% at 20 .
  4. Indoor conditions of mounting, dry and free from dust, smoke, corrosive gases, vapors or salt.
  5. The products withstand the direct vibration test on intensity with 0.4g three sine waves, which is correspondently 9.0 Richter scale.
  6. Pollution level: IV
