Home Product Medium And High-Voltage Transformers JSZY19-20R

THREE-PHASE VOLTAGE TRANSFORMER

Applicable working conditions

◆ Altitude: ≤1500m (Please indicate height above sea level if it is used in highland area)

◆ambient temperature：5℃ ~40℃.(If there any requirement,please indicate in the order)

◆relative humidity：≤85％

◆The installation site is free from gases,vapors,chemical deposits,dust,dirt and other explosive and corrosive media that seriously affect the insulation of the transformer,and there is no severe vibration or jolting.

Precautions

◆While the primary current goes through current transformer,the open circuit of secondary winding is not allowed,other wise high voltage will produce and affect the performance of product.

◆The short circuit of secondary winding of voltage transformer is not allowed,otherwise the transformer will be burned.

◆The repeated power frequency withstand voltage test of primary winding shall be conducted under 80％ of stipulated test voltage valu
